An aluminum expedition catamaran.

By Dieter Loibner , Apr 5, 2022

With 110′ LOA, a 35′ beam, and 45′ (33.5m, 10.6m, and 13.7m) of bridge clearance, the H-2 catamaran seeks to make a case for U.S. custom boatbuilding.

Hauling toys beyond the horizon is the raison d’être for a rugged go-anywhere catamaran designed and built in the U.S., a notable exception in the world of big yacht projects.

Gunboat might have left town, but there’s another big catamaran under construction in its old facility in Wanchese, North Carolina. It’s called H-2 , short for Hippocampus 2 , a stout 110-footer (33.5m) that liberally and intentionally quotes from the expedition/workboat vernacular. It’s built from aluminum and was conceived to go to the back of the beyond, where adventure beckons and Vessel Assist doesn’t operate. Aside from commodious and cushy accommodations, the boat offers grid autonomy, ocean-crossing range, and cargo capacity to match the mission of hauling a 26 ‘ (7.92m) tender, a 17 ‘ (5.8m) skiff, a two-person submarine, a four-seat ATV on the main deck, and a small helicopter on the flight deck aft.

The boat was commissioned by Brian Schmitt, 67, a real  estate executive in the Florida Keys, who pilots his own plane to commute to the Bahamas, where he keeps Hippocampus , his current 57 ‘ (17.37m) cold-molded wood/epoxy catamaran. I asked him about the jump from 57 ‘ to 110 ‘ . “I never thought I’d have the ability to do that in my own boat until probably the last few years,” he replied, adding that “it would be 120 ‘ [36.58m] if I had to do it today.”

Its predecessor, Hippocampus, built in wood/epoxy, was launched in 2003. At 57′ (17.37m), it is about half as long as H-2, but with 22,500 miles under its keels, it was a useful starting point for designing the new vessel.

Wearing shorts and a shirt with the new boat’s name and logo to our meeting, Schmitt talked openly about his project, which he manages as attentively as his real estate brokerage with 130 agents. Communication is his thing, responding to e-mail questions in near real time (in ALL CAPS) and talking to contractors directly. No project manager.

A passionate diver who habitually explores remote and exotic locales, Schmitt said he was happy with the first Hippocampus , which has three staterooms and cruises at 15 knots on twin 370-hp Yanmars. “It was the vehicle that got our 17 ‘ tender wherever we needed it.” But running the little boat 60 or 70 miles a day lost its charm. “One of the things I wanted was a twin-engine tender that would have more room for dive gear. That ended up being a 26 ‘ Calcutta, so I needed a bigger mother ship.”

With accelerating climate change, the carbon footprint of ships and large yachts is under scrutiny, but hydrocarbons still win when speed, range, and payloads are priorities. While H-2 doesn’t break the mold there, Schmitt pointed to the project’s virtues as a U.S. domestic build. “You can’t complain about global warming when you’re flying around in your G500 jet that’s contributing more CO2 emissions than anybody else in the world,” he said. “You can’t complain about all the boats being built in Germany, The Netherlands, and Italy, and then go buy a boat [there].” Schmidt wanted to build locally, keeping jobs and money in the U.S. Besides, he noted, this approach simplified communications and enabled him to personally check on progress during COVID. Perhaps most importantly, he could pick a team of trusted and compatible mates to turn his dream into a boat.

The vast build hall left vacant when Gunboat left Wanchese, North Carolina.

He selected John Marples, a fellow pilot, inventor, and multihull specialist for the design and Felix Herrin to build H-2 . Both men had worked for him on Hippocampus , and their familiarity helped when meeting today’s challenges, such as damaging trade tariffs that drove up aluminum prices, and a pandemic that killed millions, wreaked havoc on global supply chains, and caused labor shortages in industrial sectors. These factors have conspired to delay H-2 ’s launching by roughly two years and counting.

Advantage Aluminum

A key decision early on was to build in aluminum, which promised a robust structure but required extra steps to deal with corrosion and noise mitigation. “Construction was reduced to something simple—a V-bottom deadrise model, stretched out,” Marples explained. “There wasn’t any benefit to round bilges on an aluminum boat. You’d have to add internal structure to support the flat panels, and it drives the cost and difficulty of construction way up. We’re talking about a speed-to-length ratio of 2 or less, which is not a big deal. His current boat would do a speed/length of about 3, so the extra length means that you’re never really pushing the boat that hard, so shape was not a huge consideration.”

Marples and Herrin go back at least three decades to their mutual acquaintance with naval architect and boatbuilder Dave Dana, who assisted Marples with the hull design for Admiral Pete , a catamaran passenger ferry still serving Puget Sound. Herrin works with different construction materials, but having built crew boats for Petróleos de Venezuela (PDVSA) at Sea Force in Palmetto, Florida, he has spent considerable time with aluminum.

Taking a break during IBEX 2021 are builder Felix Herrin (left) and owner Brian Schmitt. H-2 is their second joint project with designer John Marples.

The structural components on H-2 are 5083-H32 alloy aluminum plate and extrusions of 6061-T6 alloy. Scantlings, materials, and weldment comply with the American Bureau of Shipping’s (ABS) 2016 design guidelines for pleasure motoryachts. Hulls and wing structures have transverse frames and bulkheads spaced on 36 “ (0.91m) centers. Those frames are supported by substantial centerline vertical keels (CVKs) welded atop twin 3 “ x 8 “ (76mm x 203mm) solid extruded-aluminum-bar keels. Intermediate subframes in the forward and aftermost hull compartments strengthen the hulls for operating in ice. Schmitt indicated he wants to traverse the Northwest Passage. For the same reason, there’s 3⁄8 “ (10mm) plate running the length of the boat above and below the waterline.

The topside and underwing plating is primarily ¼ “ (6mm), with areas of 5⁄16 “ (8mm) to strengthen slamming zones in the bow. The main deck plating is also 1/4 “ while the foredeck plate is specified at 5⁄16 “ . The bottom plating is 5⁄16 “ in the aft two-thirds of the hull and 3⁄8 “ forward. “We built all the frames and bulkheads first, then scarfed together the keel sections [and] lined those up on the bunks that we built on,” Herrin explained. “We welded the CVK on top of the keel, then started installing frames.”

Hulls and wing structure have transverse frames and bulkheads on 36″ (0.91m) centers. The hulls are supported by centerline vertical keels.

Herrin said he changed aluminum suppliers midway through the project, sourcing from Bayou Metal Supply , an ISO 9001:2015–certified distributor in Slidell, Louisiana. “We sourced the material from Greece and from domestic suppliers,” said Taylor Smith, who handles Bayou’s sales. Tariffs, he said, did not slow down business much, but the aluminum cost more. “Felix sent cut files. We had the material in inventory, we cut it, processed it on a router, and shipped it on time. Everything flowed well.”

Naval and structural engineering and detailing was contracted out to Van Gorkom Yacht Design in Portsmouth, Rhode Island. “My first responsibility was looking at structures,” Geoff Van Gorkom said. “Given that this is an aluminum yacht, we can do literally all the structures in 3D and have all the metalwork precut before it came into the yard. All the frames and longitudinals and all the primary structure were precut, which saved huge amounts of time.” Van Gorkom said he uses Rhino 3D and some of the numerous modules such as Orca 3D for hydrostatics and hydrodynamics, and 2D AutoCAD to produce construction details.

Helping save time and money, 3D-modeling allowed frames, longitudinals, and the primary structure to be cut before being sent to the building site.

Van Gorkom observed that H-2 is not a fussy high-performance vessel that needs minimum weight to achieve maximum speed. Besides ABS guidelines that address torsional loads in catamaran structures, he also consulted A.L. Dinsenbacher’s paper “A Method for Estimating Loads on Catamaran Cross-Structure” ( Marine Technology , Vol. 7, No. 4, October 1970) to estimate load conditions in beam and quartering seas. “This is going to be a very stiff boat. It’s going to be a very strong boat simply because it has to be, and that was one of the criteria that Brian put out there right from the very start of the project. The boat is sturdy and stout, a strong expedition yacht.”

Van Gorkom also engineered the setup for a folding deck crane housed under a flush hatch in the helideck on the port side to launch and retrieve the two-man submarine or the ATV. “It’s basically an enclosure that opens up, so the crane extends out,” he explained. “It comes up on a telescoping pipe to swing out and pick up something from the side of the boat.” It required support from beams on each side of the crane and cutting a slot in the helideck for the lifting bridle so the loads can move inboard or outboard. On the starboard side, the 5,500-lb (2,492-kg) Calcutta tender is an even heavier load moved by twin overhead beam cranes. The 17 ‘ Twin Vee is launched and retrieved from the foredeck with a 2,500-lb-capacity (1,153-kg) crane.

Catamarans are known to be weight-sensitive, so how will H-2 handle the weight of all the toys and high superstructure? The arch over the flybridge is 33 ‘ (10.05m) above waterline, Van Gorkom confirmed. “Add another 10 ‘ [3.05m] for the radar, mast, etc., so a comfortable bridge clearance would be around 45 ‘ [13.7m].” Marples conferred with Van Gorkom about the effect of the added weight on the center of gravity, which was deemed “almost imperceptible,” Marples remembered. A quick calculation suggests that a 5,500-lb deck load is equal to only 1.57% of a full-load displacement given as 350,000 lbs (158,550 kg).

High Power, Low Noise

Van Gorkom hired engineers at HydroComp to evaluate the design’s hydrodynamics and propulsion systems, including the influence of hull-shape parameters and demi-hull spacing on resistance. HydroComp also offered a speed-power prediction to aid with engine selection and recommended optimum shaft rpm and propeller parameters. Technical director Donald MacPherson, who prepared the report, outlined the process and findings: “Particularly interesting for this project was the use of its novel analytical distributed volume method [ADVM] for the vessel’s resistance modeling. This 2D technique (between parametric methods and CFD) uniquely allows for assessment of the influence of local sectional area curve regions (such as ‘shoulders’ or inflections) in wave-making drag. It also directly evaluates the effects of catamaran hull spacing.” HydroComp helped optimize the hulls by identifying the regions that contribute most to wave-making drag, and securing a 3% reduction in total drag at the design speed by making what MacPherson called “very minor changes to the immersed volume distribution.”

Rob Ayers works on the installation of the starboard engine’s Evolution Marine Shaft System that will be fitted with a 36″ (0.91m) five-blade propeller.

That simulation was mapped to benchmark performances of four similar catamarans, and the process was run for two design variants, followed by a propulsion simulation for partial-load conditions. The hull-spacing study concluded that the originally designed 35 ‘ (10.7m) beam remained suitable despite the boat being 20 ‘ (6.1m) longer than originally drawn. The chosen propulsion system comprises two MTU 10V 2000 M96, 1505-mhp diesels with ZF 3000 flange-mounted marine gears, providing an estimated top-speed range of 20–22 knots, cruising speeds of 12–15 knots, and 10–13 knots for long-range voyaging. Actual performance will be established during sea trials.

The recommended propeller specifications developed by HydroComp were for five-blade models with 36 “ dia­meters. HydroComp applied Prop­Elements, a wake-adapted propeller-analysis tool, to determine the advisability of installing a nozzle or shroud to restrict transmission of pressure pulses to the hull and to create a more uniform inflow. This would reduce interior noise but would increase appendage drag and power demand. Schmitt said he will wait to see if cavitation or prop noise is an issue before making a final decision.

He invested heavily in noise and vibration mitigation, knowing that an aluminum boat won’t provide the natural sound-dampening of a wood/epoxy structure like that of his first Hippocampus . Consulting with Soundown of Salem, Massachusetts, Schmitt wanted to replicate what worked well on his old boat, starting with the Evolution Marine Shaft System, in which the prop shaft runs in an oil-filled tube and uses roller and needle bearings instead of standard water-lubricated bearings. “You have a lot less shaft noise, but one of the primary benefits of an integral thrust bearing is that it transmits all the thrust directly into the hull, as opposed to pushing on the gearbox or the engine and gearbox combination,” said Sam Smullin, Soundown’s marketing and quality assurance manager. “It allows for a much softer engine mounting, so you reduce the noise from the shaft itself and get a much quieter engine installation, which reduces structure-borne noise.” Because of the relative weight sensitivity of catamarans, Smullin said, “it’s particularly important to do a really good job on the driveline.” His father, Joseph Smullin, president of Soundown and J&A Enterprises Inc., an engineering firm for noise and vibration control, estimated that this could reduce driveline noise levels by 5 dBA to 10 dBA compared to a conventional system.

Clemente Perez, one of Herrin’s build crew, works on the interior. The extensive sound and thermal insulation includes foam sprayed into the cavities.

Soundown also looked at the two 38-kW Northern Lights gensets, which have double-isolation mounts to reduce structure-borne noise. The firm also recommended structural changes to ensure that the mount foundations were as stiff as possible.

Energy from propulsion or generator engines invariably transmits to the boat structure and then resonates through big, flat panels like bulkheads, decks, ceilings, and liners, causing the familiar vibrating rattle. To dampen those vibrations, Herrin said he used Roxul, a lightweight, semi-rigid stone-wool insulation for fire resistance and sound control. His crew also sprayed cavities with Dow Froth-Pak, a quick-cure polyurethane foam for thermal insulation, and installed Sylomer (a microcellular PUR-elastomer) between the structural components and the floors, walls, and panels. “We glued the Sylomer, which is kind of a spongy foam, to the structure of the boat, and then the plywood of the subfloors and walls are glued to that,” Herrin explained, adding that this created a floating interior without any fasteners.

The plywood, called QuietCore, is a composite sandwich panel comprising marine plywood skins and an acoustic damping layer that converts acoustic energy into small amounts of heat that are dissipated. Soundown claims that an 18mm (0.7 “ ) QuietCore bulkhead can reduce noise transmission by up to 10 dBA, an audible reduction 50% greater than with regular marine plywood of equal thickness.

Electricity for a Small Town

Going off grid on H-2 does not mean anyone will suffer, as long as the electrical system keeps powering the boat’s myriad house loads—hydraulic Maxwell windlasses and thrusters; a Webasto air-conditioning system; two full-size stand-up freezers, two refrigerator freezers, and two under-counter refrigerators in the galley, all by Vitfrigo; Krüshr compactors for recyclables and garbage; Headhunter sewage-treatment system; Alfa Laval fuel-polishing system; two FCI watermakers; a complete set of Garmin navigation electronics with full redundancy; and a Böning vessel control and monitoring system.

Two Northern Lights 38-kW gensets are the heart of H-2’s AC system, which also includes a 37-kW Atlas inverter to connect to shore power in foreign ports.

Much of the AC side was designed and specified by Ward’s Marine Electric in Fort Lauderdale, Florida, in cooperation with OceanPlanet Energy of Woolwich, Maine, and principal Bruce Schwab, who helped design and integrate the DC components. “Today there’s a big trend in the industry to use shore-power converters as inverters and superlarge lithium-ion battery banks to provide power, at least temporary power, for major loads like air-conditioning, chiller plants, and things like that,” said Ward Eshleman, chairman of Ward’s Marine Electric. “So, rather than using only smaller inverters and synchronizing them and stacking to get additional kW, the trend for the larger vessels is to use shore-power converters as inverters. There is an inverter bus in the main switchboard.”

True to its go-anywhere mission, H-2 was fitted with an Atlas 37-kW inverter to connect to shore power in places that do not serve 60 Hz, 240V single-phase power. “We can take anything from 90V to 400V and pretty much anything from below 50 Hz to the 60 Hz and single- or three-phase,” Herrin explained.

Eight GTX24V315A-F24 lithium-ion batteries from Lithionics are split between a house bank that can run all DC loads for at least 24 hours, and an emergency bank to operate critical DC loads—display screens, radios, nav lights—for 24 hours. The boat is equipped with 10 Solara Ultra-S 160W panels paralleled in two groups of five each, connected to two Victron SmartSolar MPPT 100/50 solar controllers to charge the house bank. Given enough sunshine, solar and battery power should be “capable of running lights and refrigeration but not air-conditioning or heating,” Schmitt said. “Since we will likely spend most of our time in the tropics, we did not believe that solar power alone could do the job we needed.”

OceanPlanet Energy specified four Victron Buck-Boost DC-DC converters, two for each engine, to help charge the house bank from the starter batteries without having to modify the engines’ stock alternators, which would have voided the warranty. “The converters activate based on the input voltage from the starting batteries,” Schwab explained. “With lower rpm, the alternators would not produce enough current to feed both converters without the starting-battery voltage dropping, turning the converters off. Then the voltage will rise, the converters turn on again, drop the voltage, turn off…over and over. Staggering the input voltage cut-in, hopefully starting the converters one at a time, will more smoothly supply power to the house bank across the engine/alternator rpm range.”

OceanPlanet Energy specified the DC system including DC/DC converters and hefty battery banks to power house loads and critical electronics.

There are two 4,500-watt 240V split-phase engineroom-ventilation fans connected to two Victron Quattro 5-kW 24V inverter-chargers configured for 240V/120V split-phase AC loads. They can accept AC inputs from two sources (shore power or generators) and automatically connect to the available source. “In the event of a grid failure or power disconnect, they take over the supply to the connected AC loads by inverting from the Lithionics house-battery bank,” Schwab said.

“It’s more complicated than that,” according to Herrin. “Typically, we’re going to be operating with the A-bus and the B-bus tied together, so we can power everything with one generator. The B-bus actually passes current through the Victron inverter-chargers on its way to the load. We have the ability to split the A-bus and the B-bus and run the A-bus on one generator and the B-bus on the other in the few instances we’re exceeding the capacity of one of the generators. If we lose both generators, then the essential loads are still going to be carried,” meaning engine vents or water pumps.

Redundancy and emergency backups also figured largely in the deliberations of John McKay, manager of the Switchgear Systems Division at Ward’s Marine Electric and point man for this project.

One of his challenges was limiting the voltage drop in the estimated 53 ‘ (16.2m) cable run between engines, which in an emergency allows the starboard engine to be started from the port battery and vice versa. “For a starter group, you can allow a 20% voltage drop,” McKay said and noted that starting the engines requires 720 amps, while the gensets needed only 200 amps. “I was keeping the 720-amp current between 7% and 11% voltage drop, getting up to some pretty good-sized copper. Some sections of the run were 240mm2 [500MCM] cable.” Knowing that the boat is capable of going to high latitudes, McKay recalled his youth and the frigid winter mornings in Massachusetts, “where you can crank a diesel all day long at a low rpm, and it’ll never start. You just need to turn it over one or two times at a higher rpm, and it’ll be running. So, I was making certain that the starter was going to crank at the highest rpm possible and not lose it all to voltage drop.”

Protecting Assets and Finishing the Job

No matter how fast or how far H-2 will travel, corrosion caused by galvanic current between dissimilar metals, by stray currents or by electric fault, is an enemy that needs to be kept in check. That’s the calling of Ted Schwartz, who runs Electro-Guard (Mount Shasta, California). He’s one of the country’s foremost experts on cathodic protection, and also served on ABYC’s E2 Cathodic Protection Project Technical Committee.

“We designed the system and supplied all the equipment and steered them through the installation,” Schwartz said. It’s a 15-amp impressed-current-cathodic-protection (ICCP) system, model 715 A-2, with three anodes and two reference cells. Regarding the boat’s Evolution shaft system with driveshafts running inside an oil-filled tube, Schwartz said: “It was a real challenge because you can’t actually make contact with the propeller shaft on the inside of the boat.” He consulted with Soundown and found a solution. “At the coupling on the inboard end of the tube, a bit of the shaft stuck out through the seal,” Swartz said. “There’s this coupling that Soundown built that fastens to the shaft, and we asked them to provide a surface on that coupling where we could put our silver slip rings on [to provide an electrical connection] to protect props and shafts.”

Every anode can deliver up to 5 amps of current using its own current controller that receives a signal from the main controller, which determines exactly how much current each anode will put out. The entire system consists of three anodes, three current controllers, the main controller, and a separate monitoring station connected to the controller by signal cable. Later, Schmitt also ordered a backup system employing aluminum sacrificial anodes.

On catamarans, the company installs a reference cell aft near the prop of each hull, and an anode on the aft section of each hull, and one anode amidships on the inboard side on one hull.

Chromate, two layers of epoxy, copious amounts of fairing compound, and various primers rendered the surface fair and ready for a yacht-quality paint job.

At the time of this writing, the vessel had been shot with chromate and two layers of epoxy before approximately 500 gal (1,893 l) of fairing compound and 325 gal (1,230 l) of various primers rendered the surface fair and ready for a yacht-quality Alexseal paint job with 35 gal (132.5 l) light ivory, 24 gal (91 gal) stark white, and 2 gal (7.6 l) cordovan gold. Parallel to the exterior, construction was on the home stretch with installation of the crew quarters and the saloon overhead. On the systems side, pressure checks were performed for hydraulics and plumbing.

Since H-2 is a much larger and more complex vessel than the original Hippocampus , with a multitude of systems that need to be managed, monitored, and maintained, I was curious how many crew Schmitt was planning to hire to help run his new boat. He said he consulted with captains and headhunters, and “the consensus is three or possibly four at most. I just completed my 100-Ton Masters and will build time on the new boat as well. We won’t charter and are not accustomed to being cooked for or served or having our beds made and all that. So mostly I’m looking for a qualified captain and engineer to maintain the systems.”

Little surprise that a hands-on operator like Schmitt does not want to cede too much of the game he loves to play. But as big, bold, and broad-shouldered as H-2 will be when she finally emerges from the old Gunboat shed in Wanchese, the proud owner is quick to remind anyone that it’s still “a vehicle to get the toys wherever.”

H-2 : The Designer’s View

H-2 ’s owner, the adventurous Brian Schmitt, has dived into deep caves to see submerged caverns, hand-fed large sharks that would normally view him as food, and spent years in his off-time exploring Caribbean archipelagos in Hippocampus, his current 19-year-old 57 ‘ (17.4m) power catamaran. Nearing retirement age, he gave the order for his “ultimate” yacht.

The foldable hydraulic deck crane to launch and retrieve a two-man electric submarine or an all-terrain vehicle required cutting a slot in the helicopter deck for the lifting bridle.

The first talk about the new design was between the owner, the builder, and me. As we discussed the mission of the boat, it became clear that it would fall into the category of expedition vessel with more guest staterooms, more range, and more room for equipment than his old boat. Brian defined the function of the vessel as a carrier for a 26 ‘ (7.92m) twin-outboard catamaran, an outboard skiff, a small car, and a small helicopter, which needed a flight deck. This vessel was to be used with family and guests while also serving as an operations base for outbound travel by air, land, or sea.

Aside from commodious accommodations, a key requirement was comfortable motion on rough seas. This was to be a catamaran, like his current boat, which offers extensive real estate afloat in a seagoing vessel. The only restriction for the new design was a beam no greater than 35 ‘ (10.6m) to fit the largest Travelift.

The trade-off for overall beam width involves room versus roll motion. A wider catamaran responds more quickly to roll in seaways but with less amplitude, whereas a narrower beam rolls more slowly with slightly more amplitude. The slower roll is preferable as long as overall roll stability is maintained. Roll in catamarans is unlike roll in single-hulled vessels. Because the vessel is supported by two buoyancy chambers (hulls) with distance between them, motion has little to do with roll inertia, but rather with response of the hulls to the seaway. Each hull responds to a passing wave independently by heaving (up/down) and rolling, which is a circular motion around the center of gravity (CG) that translates to lateral motion when standing above the CG, especially high up on the bridge. Power catamarans, unlike sailing catamarans, do not require wide hull spacing to generate righting moment (to support a sail plan), so they can have closer hull spacing, which still preserves sufficient stability, slows wave-response roll characteristics, and takes up less space in port.

One of the expected routes for this vessel is the Northwest Passage over the top of North America. Boats venturing there can expect floating ice, so we added thicker hull plating at the waterline and an ice-separation chamber on the cooling water intakes. We also designed the hull to give the propeller protection by positioning it behind a deep canoe-stern afterbody with no exposed shaft. A rudder horn, below the propeller extending aft from the hull, adds support for the rudder and protection for the prop. This configuration is useful as a hedge against the possibility of grounding. In fact, this boat can be careened on the beach between tides if necessary for repairs. The hull includes a strong, deep, vertical keel structure that allows for blocking anywhere along its length.

Speed and range became the largest determinates of the design. A maximum range of 4,000 miles at 15 knots (enough to cross the Atlantic Ocean) was proposed. Catamarans are easily driven at modest speeds due to lack of significant wave resistance by narrow hulls. A preliminary speed prediction analysis showed that we would be in the ballpark with about 1,400 hp (1,050 kW) and 5,000 gal (18,925 l) of diesel per hull. The final installed fuel capacity is 12,500 gal (47,313 l).

The general arrangement plan shows crew quarters in the hulls, three guest cabins, office, saloon, and galley on the main deck and owner’s suite on the bridge deck level.

A totally new design normally goes through a lengthy proposal and critique cycle between designer and client, especially if the client is knowledgeable and involved. The vessel’s first iteration started at 90 ‘ (27.43m) LOA, but it became evident that it needed more length to relieve a number of ills. After adding 10 ‘ (3.05m) we saw improvements, but it wasn’t until the 110 ‘ (33.5m) length proposal that we felt all the requirements had been satisfied: more slender hull shape, more open interior space, and better placement of machinery and tankage. The flight deck for the helicopter became larger, and the forward superstructure fairings gave the boat a sleeker look. And at 110 ‘ we achieved an efficient length versus waterline beam ratio that reduced wave drag and fuel consumption at the target cruise speed.

While beam remained at 35 ‘ , lightship displacement increased significantly to 230,000 lbs (104,190 kg). Accommodations now include crew quarters for four persons in the bows; three double guest cabins and a ship’s office forward; a large saloon amidships with adjacent galley, and a dive and a storage locker aft on the main deck. The upper deck is arranged with a full-width-bridge steering station forward, protected by a Portuguese bridge, and a master stateroom with en suite bathroom aft. The flight deck extends aft of the master stateroom. Access to the upper deck is by either a staircase from the foredeck, an interior staircase adjacent to the ship’s office, or by stairs from the starboard side deck.

The largest variable weight on the boat is fuel, so the tankage is located amidships to minimize its influence on trim. Engine and machinery rooms aft of the tankage take up the remaining spaces all the way to the transoms. Other amenities include a utility area aft of the crew quarters port side with storage and washing machines, and a walkway through the tank spaces and enginerooms to the boarding decks at each transom. Another late addition is the flying bridge to aid with shallow-water operation by improving the vantage point to see coral heads and other obstructions. Its protective bimini serves as a mounting platform for lights and antennae.

OUR HISTORY

In conjunction with Sea Speed Designs, experience has been gained over 35 years in the boat building industry, specializing in everything from Mega Yachts to Ferries. SeaCat Ships offer custom designed and built Aluminium Catamarans made specifically to suit the needs of the keen owner/operator.

These high speed, long-range aluminium cats not only look great, but also perform to a very high standard. Our Cats are assembled in Thailand by our Australian/Thai team, with a lot of the components coming from Australia and many of the sub-contractors also being of Australian decent. For Example: “Aqua Quest” is a state-of-the-art dive boat built for daily rough water operations from Cairns, Australia out to the Great Barrier Reef. After the sea trials and commissioning in the Gulf of Thailand, she sailed on her own hull to Cairns via Bali.

We have access to over 100 proven hulls from 6 to 42 Metres, all built to the highest international standards. The aluminium hull and deckhouse design is very strong and is in compliance with the requirements of Lloyds Register SSC rules for a passenger vessel operating offshore. The majority of the aluminium structure was supplied in KIT format to allow the parts to be CNC router cut for ease in construction.

SeaCat Ships offers custom designed and built aluminium catamarans. Crafting high-performance aluminum boats in the heart of Asia. 35 years in the boat-building industry. Redefining speed, comfort and affordability at sea.

SeaCat Ships is fundamentally a family owned and run company, with management carried out by Paul, Vicki, and Mari-on Birgan.

Paul (Managing Director) who has just been awarded WBW’s “Designer of the Year Asia” Award for 2017, has 30 years experience in the design and construction of aluminium vessels. Paul handles all new enquires, as well as the ordering process from commencement to completion.

Vicki (General Manager) manages the Shipyard and oversees the day to day running of the office and it’s staff.

Mari-on (Marketing Manager) manages the marketing side of the business, including the SeaCat Newsletter, Website and Social Media Channels.

Construction in our Thailand Shipyard, happens under the watchful eye of Murray Birgan (Project Manager). Murray works with a team of expats to carry out supervision, training and quality control.

With decades of boat-building experience between them, the team ensures a high quality of new-builds. They are now passing on their expertise to their Thai employees, many of which already have extensive experience in aluminium fabrication and welding and are quick to pick-up the specialised skills required at SeaCat Ships.

SeaCat currently has 5 expatriates and 50 Thai employees, as well as a further 20-30 part time Thai sub-contractors. We are also supported by Australian suppliers and sub-contractors.

CAT OR TRI?

Taken from The Design File, Tony Grainger Yacht Design. 

“CATS have become more popular for cruising mainly because of the accommodation space and privacy they provide and because for a given length they are faster and cheaper to build than a trimaran.  TRIS, on the other hand, provide good performance through a wider range of conditions than catamarans, and can also be effective for cruising by utilizing flare above the waterline in the main hull, and by fitting aft cabins where additional privacy is required in the accommodation layout. Apart from the accommodation, the trimaran provides a more forgiving motion in a sea way and better resistance to pitching if the hull shapes are well designed, and the wide beam allows it to carry more sail in fresh conditions. Against these advantages is the fact that a cat will require less berthing space and is likely to be more maneuverable in close quarters if twin diesels are fitted. Also, the cat will have a more steady motion than a tri while sailing downwind.”

I built my first multihull in the 70’s and it was a Trimaran, foam cored, TriStar design, a great multihull.  Now I am building a cat for my wife and I, mainly because of the room, very wide main salon and stateroom and big aft deck and flybridge.  The Tri was maybe a bit more sea kindly than the cat will be, but besides not having to build a third hull, she will be a bit faster as well as maybe a bit more economical.

Can I have what I want ?

But you must stay in the boundaries of the designer structural requirements i.e.. mast placement, weight to be carried and where. All the multihulls we have built over the last 42 years, have been what the clients have wanted, inside and out. Once they find the size they think will work, we find the basic design and designer for their dream platform to create it.

The final look is up to you, either with your drawing or pictures or work with one of several concept artists we know to help. Same with the interior, your interior designer, pictures or cut out from magazine of things you would like or we can line you up with someone to help. You work directly with these people, pay them directly to go as far as you want or need to, the do not work for Pedigree.

How long does it take to build your dream?

Based on our first price estimate, a basic 60′ power or sail typically takes about 24 months. This would be a very nice Cat, but not a lot of fancy, expensive items on board (gold faucets etc.) Engines, hydraulic steering, electric heads, windlass, gen.set, etc., very nice, but not a lot of goodies. The second price we show is with almost everything clients really want onboard, Watermaker, A/C, Shore boat, TV (s), fancy wood decor and custom items and electronics. This, of course, also adds more time to construct, maybe 6 months, You can also have us build to a certain stage and you take her home and finish the build or stretch out the time to build to fit your schedule or investments. If you add 6 months to each of these times, it would be for a 75′-85′ and 6 months to that and you would be in the 100′ range.

Taking her home from here or maybe cruise the San Juan islands, inside passage to Alaska first. Clients have also taken them to Vancouver and had them shipped to Florida or hire a crew to deliver them to where they want.

Why does Pedigree Catamarans, Inc. post our prices online?

We have been building multihulls since 1975 and we know how many hours each boat should take to build, even custom boats since we do not build production boats.  Other companies may not have built or built enough boats to determine the cost.  Granted boat costs vary directly with the customer’s requirements, however the hull build should not vary much.

Also, we do not have “salesmen.”   We are a owner/operated business that talks directly with each customer based on our 42 years of boating and cruising experience.  We believe that you want a cat of your own, not what a production builder thinks everyone should have.

I would be very leery of a company who wants large deposits up front and can’t provide basic prices to a customer.  What we are hearing now from people that have paid a large deposit up front, only find the builder wants more and more and exceeded their guess of the cost and time line.  Then the worst, they want more money or they will sell the cat to someone else, holding it for ransom from the highest bidder,  Our clients chose to pay as we build and the cat is 100% theirs from the start and definitely no large deposit up front. 

How much does a custom catamaran cost?

The cost of a custom Pedigree catamaran, constructed with foam core, composite construction is very close to that of a production built yacht.  The advantage is, you will have exactly what you want and the disadvantage is, it will take a little while to build.

Charter cats are generally a lot less expensive. They do not need the big ticket luxury items, such as water makers, A/C, big gen. sets, fancy interiors, etc.

When we have an opening to start a new project, you can have just the hulls built and finish the catamaran yourself at a considerable savings at your home port.  If you wish, we can provide you with a cat at what ever stage you like. For example, we can fit the engines and aide in completion and when you are ready to launch, we can arrange that as well.

Most of our catamarans are fully loaded and ready for cruising.  We have listed the average cost clients have spent on our amenities and pricing page. For a list of some of amenities included in a Pedigree Cat and the average prices, click on the “Amenities & Pricing” button available from most pages on our site.

Over the last 20 years, the clients have chosen to pay as we build and they have approved to have done as well as what we purchase for them, engines etc.. 

All and all, we can provide just about anything you and your budget can imagine. Our goal is to get you out there to enjoy the fun with  the exact Catamaran you have always wanted.

I think we are about the only builder that shows you the price you might spend on you dream, it’s up to you and what you want and need.

Why do Production Cats depreciate so much more than a quality custom built cat?

Several reasons. One might be, that every cat produced is probably from the same mold and in most cases, several years old and not updated or no improvements incorporated over any previously produced. Thus no real reason to get a new one if you can get the same one used for a lot less. The owners must lower their asking price far enough below the new ones that it will make it desirable. The price on the same new cat, next year, must be in line pricewise, in the marketing field to be sold, thus last years model must be substantially lower.

The production cats do not provide the clients with what they expected in a catamaran. Lacking in performance, require a lot of power to move them at a reasonably expected speed, to narrow to give the stability and the room onboard they were led to believe they would have. Deeper draft than expected, very heavy solid fiberglass construction, noisy, sinkable, sweat and hard to maintain a comfortable temperature inside. Most are imported and can not be used for charter in US waters.

One of our custom built multihulls came up for sale, built in 1980 and sold for $60,000 more than it cost the owners to have it built back then.

Even today, we have people trying to buy the clients cat we are constructing from the client and at a substantial amount more than they have into their dream. Problem is, this is their dream and it is not up for sale.

Let us build your custom dream yacht!

Gary habersetzer started building multihulls in 1975 in washington..

In the late 70’s, the first Airex foam core Trimaran in the USA, a TriStar 42′ “Amenity” was built by Gary.  The designer, Ed Horstman was as excited as he was to build a composite Multihull and ended up writing an instruction manual based on Airex information in conjunction with ABS standards.  At that time, there was no one in the USA that was building composite Multihulls.

Bloomfield 86’ Custom Catamaran

This is a great place to start if you ever wanted a custom catamaran…saving over 2 years of construction time.

Now, about the custom catamaran…..This cat is 86′ long and 42′ wide and with keels and can be beached or set on a spit at low tide to do clean up or repaint bottoms. She is a custom composite catamaran built with Airex foam core, tri- and bi-axial fabric and Vinylester resin, carbon fiber and epoxy resin, Kevlar where needed for beaching.

Inspired in Kodiak Tailored Professional Design Built in Alaska

Alaskan aluminum power catamarans, llc.

Specializing in building aluminum, hydrofoil assist, outboard powered catamarans

Alaskan Aluminum Power Catamarans specializes in the design and building of aluminum, hydrofoil assist, outboard powered catamarans; producing a welded aluminum boat specifically designed for operating in our rugged Alaskan environment. Each of our boats is influenced by a lifetime Alaskan resident who has spent most of his life both commercially fishing and sport fish guiding around Kodiak. They are designed by an accomplished naval architect specializing in hydrofoil assist catamarans, and each boat is built here in Alaska by a team well versed in fabricating within Alaska’s Commercial Fishing and Sport Boating industry.

The catamaran-style hull is well known for its stability, extra width, and fuel efficiency. However, the asymmetrical hulls on our boats recognize that the water inside a catamaran’s tunnel is different from the water displaced on the outboard sides of the boat when underway. This design helps to further improve on the catamaran idea; preparing for and mitigating chop entering the tunnel for a smoother ride at speed, as well as minimizing drag, increasing fuel efficiency, and range.

Our hydrofoil further improves that catamaran concept and acts like an airplane wing securely fixed between the hulls, providing several inches of lift to the entire boat on plane. Lifting the boat reduces the wetted surface, thereby reducing drag, increasing fuel efficiency, speed, and range. Lifting the boat also increases the distance between the water’s surface and tunnel, further softening and improving the ride in chop. Our hydrofoils are designed and placed to maximize lift at practical cruising speeds and anticipate a variety of load conditions.

Cabin and deck layout are easily customizable and easily tailored to suit your specific tastes and goals for your vessel. We are very happy to work with you and include our own personal experiences and suggestions as we help to create your ideal platform; whether you are a charter captain looking for a layout specific to your clients needs, a remote cabin owner interested in hauling material and supplies, or any normal Alaskan looking to take family and friends out for a day or week of fun. These decisions aren’t new to us and we enjoy helping tailor this technology to your application.

Step aboard a lee shore boat.

You’ll immediately realize that this boat is entirely different from a common production vessel. It is solid as a rock and it includes all of the custom features desired by the client. This is a boat built to last a lifetime. Perfect, strong welds and attention to detail distinguish a Lee Shore boat from all of the others. Its takes some time to create a boat like this, but it’s worth the wait. A custom Lee Shore boat is the last boat you’ll ever need.

Lee Shore offers a variety of boats from over 100 of our own plans. If one of those is not exactly what you need we can design and build a boat to fit your specific needs. Whether the boat is for work or pleasure, we design a layout with enough deck and accommodation space to comfortably handle all the people, freight and amenities you’ll want to carry. More about us »

Ready to Get Started?

Request a quote for your custom build lee shore boat and join the many others having an experience that lasts..

 We offer a variety of steering consoles, T-tops and cabins styles. From a simple steering station with a wind break to a full width wheelhouse with all the amenities, we produce the structure that fits the needs and purposes of the client. For our decks we use smooth plate, which we prime and paint with a non- skid coating. We’ve learned that smooth plate with a non-skid coating is a surface much more appealing to knees and bare feet than diamond plate, and also much easier to keep clean.

Craftsmanship

We offer a wide range of options for fuel tanks, according to the application. Fuel tanks are usually installed below decks. Our custom options include, but are certainly not limited to, crab davits and haulers, side doors for diving, beach access or hauling ATVs, suspension helm seats and custom railings. We are happy to build almost anything else that that you might desire, just give us an idea of what you’re after.

Aluminum Boat Design Services &  NC Kits

Existing Kits, Custom & Semi-Custom

Why buy or build someone's model X instead of the design you want,

with the look, feel and features that you want?

"The boat is a rock star!- Our "A" boat."

~ 32' pilot boat customer

"You guys are easy to work with, and your parts fit together real well."

~ professional boat builder

"Best looking boats around."

"I definitely wanted you to know how much I enjoyed working with you and your team.  I hope that we have more oppor-tunities to work together again at some point."

~ 31' landing craft customer

Background:

Response Marine has been designing welded aluminum boats since our first fire/rescue boat in 1989.  We are the primary supplier of designs and cutting files for a number of small boat builders and metal fabricators, and we also provide designs to individuals for one-off construction.   In addition to pure design work, we have spent most of these years embedded within boat building companies providing sales work, project management, shop supervision, and even rigging labor.  This background has yielded valuable, hands-on experience from the initial design concept thru construction and sea trials, as well as an appreciation for reliable performance and good structure that is sensibly assembled, aesthetically pleasing, and ruggedly built. 

Naturally, there have been many changes and improvements in both design software and construction practices in the past 30+ years.  Our early designs were developed in a combination of ProSurf and AutoCad and were set up for hand cutting all parts from provided dimensions.  For the past 20 years or so, we have been using MultiSurf for 3D modelling and plate development and then AutoCad for 3D views and 2D detailing.  The designs offered here are selected from those created since 2002, and they include files for the NC cutting of virtually all hull parts with the exception of extruded stiffeners for decks and superstructure.

Over the years we have learned darn near everything we know from our fellow builders, co-workers and customers.  Without their wealth of experience and challenges we would not be able to offer the range and quality of design services and kits that we do today.   

"YES! We're still very happy with our boat. We had a response to the north shore a couple weeks ago, in a snow storm, 6' seas, a few 8s and 10s also, and it handled extremely well. Even on the return trip with following seas. Breaks 2-plus inches of ice very nicely, too."

~ 30' fire rescue boat customer

Typical Design Kits:

Our Design packages include a single use of the NC cutting files, construction drawings, stock lists, parts lists and often a review of the weights and trim for the intended outfitting and application.  As a result of this latter process we may recommend some changes to the existing design.  While most kit sellers have a take-it-or-leave-it approach, we are more inclined to tweak our designs to suit both the mission and the preferences of  the owner. (For more on this, please see Custom Design .)

Each design was developed originally for a specific customer and application, but in many cases these specific-purpose designs are well suited for a range of applications whether they be commercial or recreational.  In many cases, minor and cost efficient changes may be incorporated to adapt a design from one application to another.  Furthermore, some of our designs may require modification before reselling in order to avoid infringement on any elements we consider proprietary to the original builder and important to their specific markets and sales efforts.  

We find that nearly all of our customers are interested in at least some changes to existing design kits- whether it be changing a console, revising gunnels, changing between welded flanges and formed flanges, or more major changes.    Accordingly, we do not have a formal price list, but will gladly quote once we have an understanding of your project.  You will find that each project is a collaborative effort among you, the builder/owner and the designers.  For multiple builds by the same customer we generally offer each subsequent hull license for a nominal 10 to 20% of the initial cost. 

Please see  Custom Design  for a description of easy changes to look and function, as well as a more complete description of our services.

"From the initial stages of designing you have made it easy for any changes we wanted to make, without major cost over-runs. Our 28’ Response Marine with twin 350 Yamahas was something that you don’t ordinarily do, but you made the modifications based on our request, basically redesigning the vessel to meet our specifications."

~ fire boat customer

"I LOVE our boats and parts wow."

" Every body here loves it.  The craftsmanship of  your boat is what the people are really PLEASED and bragging on."

~ rescue boat customer

"I wanted to thank you again for the design work you did for us on our club launch project.  We had it in full service for our opening weekend and the membership was beyond pleased with the results.  I have attached some pics of the finished build."
