Herreshoff Marlin 23

Herreshoff Marlin 23 is a 22 ′ 11 ″ / 7 m monohull sailboat designed by Nathaniel G. Herreshoff and A. Sidney DeWolf Herreshoff and built by Herreshoff Mfg. Co. and Cape Cod Shipbuilding starting in 1958.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

This is a larger version of the Herreshoff designed FISH but with a cabin and different rig. A smaller version was originally built of wood by Herreshoff Manufacturing. The design was aquired by Cape Cod Shipbuilding where it was built of fiberglass with some modifications at the direction of Sydney Herreshoff. Besides the version shown above, another variation has a larger cockpit and smaller ‘cuddy’ cabin.

Review of Marlin 23

Basic specs..

The boat is typically equipped with a Palmer gasoline engine at 19.0 hp (14 kW), which gives a max speed about 7.7 knots.

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Marlin 23 is 1.99, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 5.5 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Marlin 23 is about 75 kg/cm, alternatively 423 lbs/inch. Meaning: if you load 75 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 423 lbs cargo on the boat it will sink 1 inch.

Herreshoff Marlin 23 in plastic

• Add to quote

I am looking at a 1965 fiberglass "Herreshoff" Marlin 23. Does anyone out there know where I can find information about this boat, which I assume is someone''s takeoff of the classic Herreshoff Fish Class sloop. I am particularly interested in what the displacement is, who built them, and your opinion. thanks, Paul Hirsch  

The Marlin was built by Cape Cod Shipbuilding. They are still in business and I believe they will still build the Marlin on request. The Marlin was a Sidney Dewolf Herreshoff design if I remember correctly. Cape Cod Shipbuilding claims to be the oldest sailing yacht builder still in continuous business: Marlin The Marlin was not a copy of anything in particular but was an original design for Cape Cod. As a teenager in the early 1960''s, I thought that the Marlin and the Goldeneye (a smaller version of the Marlin) was about as cool a boat as ever existed. I had all kinds of dreams of being able to someday owning a wonderful pocket cruiser like the Marlin and be able to sail all over Long Island Sound and New England. Of course those dreams were 36 years, or more, ago and much has changed in yacht design and my tsate in boats since then. Still, a design like the Marlin still knocks my socks off when I see them and pulls at my heartstrings with the full pull of the romance born years ago. One word of caution, Cape Cod experimented with leaving parts of the hatches and cabin sides un-gelcoated which let a lot of light down below but which in hindsight would UV degrade the cabin sides pretty badly and undermine their strength a bit over time. I believe that I actually have original literature on the Marlin in my files but alas I can''t get to my files until we are in the ''new'' house around May or June. I would try Cape Cod Shipbuilding to see if they can help. Good sailing Jeff  

I tried to respond earlier But I am not sure the message was posted so here it goes, again. The Marlin was, and still is, sold by Cape Cod Shipbuilding. In fact, they just finished their first Marlin since '67 or '68 - sold to a guy in Chicago. It was designed by Captain Nat - Nathanael Herreshoff. Originally you could get it in 2 models - a day-sailer - big cockpit small cutty cabin or the cruiser which reverses the cabin/cockpit balance. Mine, which I recently bought from a good friend was built in 1957 - one of the first 5 Fiberglass hulls. If you go to the Cape Cod Shipbuilding site check out the Atlantic 30 in the one design category - a beautiful boat.  

Well, I bought a '57 boat - movin' kinda slow all around.  

Hey Cortona, just saw your message. I have a 1965 Marlin, daysailer version. I'd love to see some pics of your boat and would be happy to share some of mine.  

'57 Marlin Brodie78 Here are a few pics of my Marlin. At the moment she doesn't look this good and I just sent the magneto off to MAine to be rebuilt - still have the original Palmer single cylinder engine - don't ask why, there is no reasonable answer. I am new to the forum and a klutz with computers so if the pics I thought I attached are still in cyberspace I'll delegate this to Mrs Cortona who is much better withkeybrds and gigabytes.  

Hey Cortona, I can't see the pics so I'll wait for the Mrs. to post them. At least you have an engine, my boat has a 2 hp outboard that I try to never use as it is loud and annoying, not to mention undersized. I managed to go all season without using it this year. Asym spinnaker helps get me home on those light air days. Once I get to that ten post limit I'll put up some pics. Trying to find some posts to reply to!  

I have nearly completed the restoration of a Marlin that has been in my family since 1960, and I remain stymied by the pronounced weather helm and whether some adjustments in the rigging might address that problem. Any ideas?  

The weather helm is a function of the steeply raked rudder post and old-style rudder shape. There are several quick things you can do to help, and a few more major ones. Easy things: Reef/ease/flatten the main before the jib. When it's time to reef, I find the boat behaves much better with a reefed main and full jib than the other way around. I have a furling jib so it's easier to just roll up some of the jib but it usually results in more helm. If it's windy enough to just use one sail, DON'T try sailing with just the main! The boat won't do it. It will, however, sail just fine with the jib only. You won't point terribly well but it can make for a pleasant sail. Try it on a day when it's not too gnarly to see how the boat does. You'll point better the windier it is, if the wind drops to a speed where you need the main, you'll know because you won't be able to sail upwind at all. More major things: Shorten the foot of the mainsail...essentially does what putting a reef in does, as far as moving the center of effort further forward. The standard boat has a very long boom as it is (the foot of my main is 11') Bowsprit...my boat has a 2' fixed bowsprit to move the jib tack forward. Not exactly an overnight project but certainly not beyond the abilities of a good do-it-yourselfer. I can send you pics of mine if you want. I have not sailed a Marlin without a bowsprit so I can't tell you exactly how much of a difference it makes. I do still have a lot of helm sometimes even with the sprit but never so much that the rudder stalls or the boat rounds up. I just heel a lot and slow down if I don't have the boat trimmed properly with the sails. I suppose the ultimate fix would be to build a new rudder with a more vertical rudder post and more modern shape, but that would be a serious project. I'd love to see what difference it made, though!  

Thx Many thanks, Brodie. I think we'll start with the non-majors!  

sold my S boat and now just bought a '61 marlin day sailor..are you people still around with your marlins for questions and support??  

If they aren't, you could always try the manufacturer... Cape Cod Shipbuilding is still in business in Wareham, MA.  

Marlin Hey Brodie78 I'd pay your freight to come down to Shelter Island and comment on how to best restore my Marlin. John Ehlers [email protected]  

bow sprit Hi, I just bought a '61 Marlin and would like to know more about the weather helm thing.....It does not have a bow sprit. If you still have it would I be better to cut the boom? Thanks John Ehlers [email protected]  

Hi all.. I have been looking into the Marlin, one of the most beautiful of small boats in my humble opinion. From what I have read here, the problem with the weather helm has a lot to do with how far forwards the rudder is compared to the size and shape of the main.. As noted, raking a reef in seems to help. Do you think cutting down the main to a gaff rig would help any? I think that, added to Starry Night's small Sprit, would make her a lot more "neutral" Any thoughts?  

A gaff rig would normally move the CE aft and increase weather helm. My sense is that the helm is pretty neutral until the Breeze builds so there is no obvious cure except reef early.

ARCHIVED: This is a previously listed vessel and is no longer offered for sale If you would like assistance locating a similar vessel, Click Here to contact the listing broker.

The Marlin is a sloop rig, with a 1500 lb. lead keel and an outboard motor well.  She is a wonderful, safe and sturdy daysailer, with a huge cockpit that seats 6 or more in comfort and high coaming that keeps water out and kids in. F rom 2007 to 2009, the Rumery yard in Saco undertook a complete overhaul of the boat. She was taken down to bare fiberglass and bright work and rebuilt and refinished from there, along with the addition of new winches, automatic bailer, self-furling jib, new suit of sails, GPS and radio, and new electrical and wiring rig. The head was removed but the twin bunks were retained. The mast was moved a bit to reduce the weather helm.  This is a donated boat to a non profit and can be acquired by Lease - Purchase.

Pipe Dreamer's blue marlin holds on, wins $1.18M in Mid-Atlantic tournament

P ipe Dreamer's blue marlin held up over the final fishing days of the Mid-Atlantic tournament , which meant a very big pay day for Carmine "Chip" Caruso and company.

Caruso, of Colts Neck, earned a tournament record $1,180,342, the most ever paid out for a blue marlin in the prestigious Mid-Atlantic, which this year drew 181 sport fishing crews from up and down the East Coast. One of the boats, it's worth noting, belonged to NBA Hall-of-Famer Michael Jordan.

The Pipe Dreamer crew, which has been fishing together for the better part of two decades, Caruso said, landed the 889-pound blue marlin at 9 a.m. Wednesday then had to hold their breaths until the scales closed at 9 p.m. Friday to see if they won.

They opted to fish out of Ocean City, Maryland, which along with Cape May, were the two eligible ports. Capt. Rich Fernandez was at the helm and Andy Confortini was the reel man on a 130-pound class outfit. Surprisingly, it only took 20 minutes to boat the huge fish, which is the third largest blue marlin in the tournament's history.

Caruso said the big billfish cooperated. The fish never had time to take a run because Fernandez backed down on it hard and Confortini got its head turned and to the side of the boat in a hurry.

In total, the tournament paid out $5.79 million to 35 boat crews. Jordan's boat Catch 23, by the way, took home $462,318 for a 75-pound white marlin, good for third in that category.

Fluke, bluefish

I took the family on the Jamaica II for the afternoon fluke trip on Sunday. Capt. Ryan Bogan steered the boat out to the local reefs outside of Manasquan Inlet. As far as the conditions went, the wind was out of the north, and the drift speed was a bit quick, though it had slowed down from the morning and continued to ease up as the day wore on. There was a lazy swell on the water.

We had plenty of opportunities to hook fluke, and I know for sure I left a couple down there. We had steady bites, though most were shorts. One in our party pulled in a keeper. The sharpies in the bow of the boat did not miss a beat tossing bucktails and an assortment of Gulp baits. Chey Baybay caught her three-fish limit as did Ryan Fityere. There were a few others with limits, though I did not get everyone's name.

Capt. Ron Kish on the Capt. Cal II out of Shark River Inlet had a fare land a 7-pound fluke on Sunday. Kish said he's drifting around wrecks, drop-offs and mussel beds.

At times, the bluefish were right on top of the water where they were easily located by the boats working the coastline up towards Sea Bright. Capt Rich Falcone on the Golden Eagle out of Shark River Inlet, said they had a good showing of bonito on Saturday. The blues were running up to six pounds. The Queen Mary out of Manasquan Inlet, had a Spanish mackerel in the mix of blues and bonito.

Travis Kelce joins Taylor Swift onstage during surprise Eras Tour appearance in London: Watch

Add Travis Kelce to the rolling credits of the Eras Tour.

Taylor Swift's boyfriend surprised 89,000 fans inside Wembley Stadium in London on Sunday by joining dancers Jan Ravnik and Kameron Saunders to revive the singer after she fell to the ground during "The Smallest Man Who Ever Lived."

Kelce picked up Taylor Swift and carried her to the bright red lipstick couch before he, Ravnik and Saunders attempted to revive her so she could sing, "I Can Do It With a Broken Heart."

The tight end attended all three nights in London sharing a VIP tent with a slew of stars including Sir Paul McCartney, Jon Bon Jovi, Hugh Grant, Cate Blanchett, Mila Kunis, Ashton Kutcher and Phoebe Waller-Bridge. His brother Jason and sister-in-law Kylie also traded friendship bracelets and posed for pictures with Swifties.

Swift's boyfriend hinted toward the fire London shows in April while promoting his concert festival Kelce Jam.

When asked what show can't be missed in Europe he announced the British capital along with her first European stop where she unveiled the new "Tortured Poets" set.

"Man, I'll tell you what, I think the London shows," he said to Entertainment Tonight. "I think she's at Wembley eight times, which is mind-blowing that she can do that many shows in one stadium and fill that thing up. I played in Wembley once, and I don't even think we filled that thing all the way up. And London's always an amazing city. Paris is an amazing city."

Swift heads to Dublin, Ireland, next.
