  1. The Fixed-Wing Is In: America's Cup Sailors Plan to Use Rigid Carbon

    SAN DIEGO—After more than a year of practicing for the America's Cup, the U.S. team is replacing its boat's lofty 60-meter mast and 620-square-meter cloth mainsail with a hard, fixed wing that ...

  2. Wingsail

    BMW Oracle Racing USA 17 from the 2010 America's Cup, with a rigid mainsail wingsail, and a conventional jib at the fore Forces on a wing (green = lift, red = drag).. A wingsail, twin-skin sail or double skin sail is a variable-camber aerodynamic structure that is fitted to a marine vessel in place of conventional sails.Wingsails are analogous to airplane wings, except that they are designed ...

  3. Have Wingsails Gone Mainstream?

    The wing's advantages under sail include greater efficiency not just to windward—the wing-equipped boat points 10 degrees higher—but also on a reach, where it performs better in light air than the conventional rig. As wind speed increases and the wing generates lift, the camber can be flattened, and the boat will sail even closer to the wind.

  4. Sailing the sea with composite wings

    RexNord (Milwaukee, Wis.) supplied the large, low-friction composite bearings that enable wing rotation on the stub axle. The X-2 is a 50-ft/15.4m long Contour 50 trimaran. It has a 41-ft/12.5m beam width, a narrow center hull and two outrigger hulls. Built by Contour Yachts (Erin, Ontario, Canada), it was engineered by yacht designers Morrelli ...

  5. Inflated Wing Sails

    Inflated Wing Sails (IWS) IWS is stable in every wind conditions. There is no pressure on the boat's structure. IWS offers a smooth balanced new way of sailing. No more winches, halyards, shrouds or complex deck equipments. «it is the first sailboat that really gave me pleasure sailing because it mixes aircraft and yachting technologies…».

  6. Sailboat Keel Types Compared: Pros and Cons of 13 Types

    The wing keel may struggle to sail as close to the wind as a similarly-sized sailboat with a fin keel, which can be a disadvantage when racing or sailing in tight spaces. ... Finally, fixed keel boats are generally heavier and harder to trailer, as they require a higher towing capacity and specially designed trailers to accommodate the boat's ...

  7. Cargo Ships Reclaim Wind Power With High Tech Rigid Sails

    Canvas sails once powered the cargo ships that sailed the 7 seas, and now the modern day shipping industry is taking steps to reclaim its wind power heritage — with a high tech twist, that is ...

  8. Rigid wing sailboats: A state of the art survey

    The SailRocket 2 (shown in Fig. 2) set the all-time speed record for a wind-powered vehicle on water in November 2012, averaging 33.44 m/s [65 kn] (speeds were set in 15.43 m/s [30 kn] winds sailing at over 2.4 times the speed of the wind), over a 500 m course in Walvis Bay, Namibia. The wing is asymmetrical, and was set up for a starboard tack to suit Walvis Bay (Sailrocket, 2018).

  9. The Catalina 25

    Under power, the Catalina 25 will make about 5- 1/2 knots with a 6-hp. outboard, and you can coax an extra 1/2 to 3/4 knot or so out of the boat with an 8- hp. or 9.9-hp. engine. (Theoretical maximum hull speed in ideal conditions is around 6.3 knots.)

  10. "Wing Yacht" Evidence: Compelling Case for Wingsail

    Already designed and tested, an Oceanwings wingsail, it claims, produces twice a conventional sail's power, plus is reefable, furlable, and automated. This wingsail is therefore a key element of Evidence. At 156 feet (47.7 meters), Evidence employs a wingsail of about 4,306 square feet (400 square meters). It stands 115 feet (35 meters) high ...

  11. Oceanbird's huge 80-meter sails reduce cargo shipping emissions by 90%

    That's not quite as quick as a conventional ship; you're looking at around 12 days instead of the typical 8, but the Oceanbird's four colossal 80-meter (260-ft) high extendable wing sails promise ...

  12. This Could Be the Fastest Boat in The America's Cup

    These, in turn, support the enormous fixed-wing sail. This sail is comparable to a jumbo jet wing in both size and function. "The goal of the wing design is to maximize thrust and lift the boat ...

  13. Fixed wing sail controls and drawings

    A sail of that size on a power cat will barely move it. Reality proves that the optimistic claims for the (alleged) advantage of fixed wings over soft sails are enormously overstated. In most classes in which they have been tried, even by experts, fixed wings were significantly slower than normal sails.

  14. Pros and Cons of the Wing Keel (5 Surprising Benefits)

    Advantages of the Wing Keel Shallow draft. The main reason the wing keel gained popularity is that it offers better clearance. The horizontal wing enlarges the keel's surface area and so it doesn't have to go as deep as a fin keel on a boat of the same size has to - the difference can easily be a foot of draft on a twenty-foot sailboat. This is quite irrelevant in the Mediterranean or Adriatic ...

  15. Fixed sails or wings

    Fixed sails or wings. Fixed installations on the ship in the form of a flexible sail, rigid sail or turbosail can make use of the wind to replace some of the propulsion power needed. All possibilities have pros and cons and must be chosen to best suit the ship type, trade and size. The savings are highly dependent on the wind conditions in ...

    Wing keel version: draft 2.83'/.86m; ballast 1,750 lbs; displacement 4,400 lbs TALL RIG: Listed SA = 295 sq ft. ... 1997), states that a boat with a BN of less than 1.3 will be slow in light winds. A boat with a BN of 1.6 or greater is a boat that will be reefed often in offshore cruising. Derek Harvey, "Multihulls for Cruising and Racing ...

    The giant sails could reduce CO2 emissions by as much as 30 percent. Cargill SHARE. A massive cargo ship retrofitted with a pair of nearly 125-foot-tall "wing sails" has set out on its maiden ...

  18. Why should we care about a rotating mast?

    When a boat is traveling with the wind coming from in front of the beam (<90 degrees) the sails operate as airfoils in much the same way as an airplane wing. Rigid wing airfoil When the wind strikes the front edge of this rigid wing, the air is separated and must travel a longer distance in the case of particle A vs particle B.

  19. What exactly is the 'lift' of a sailboat as explained by Bernoulli

    The Wikipedia article on wingsails explains the use of a fixed wing/sail and the way airflow flowing around the wing creates the force needed to push the boat. These are essentially airplane wings that have been turned from a horizontal position to a vertical position. The effect is the same because the sailboat with a center keel assumes the ...

  20. Design of a Free-Rotating Wing Sail for an Autonomous Sailboat

    Figure 54: Free rotating wing sail: "Aircraft wing set up" design parameter definition. The aerodynamic centre of pressure is marked with a red ball. The main wing surface has the span b, a tip chord ct and a root chord cr. The wing is said to be rotated around the rotation axis, z, which is the origin of the wing fixed coordinate system.

  21. Sailboat Keel Types: Illustrated Guide (Bilge, Fin, Full)

    The most common sailboat keel types are full-length keels, fin keels, bulb keels, wing keels, bilge keels, and lifting keels. Full keels are popular among cruisers, while fin keels are generally used for racing. Bilge keels and lifting keels are typically used in tidal waters, on small fishing boats for example.

  22. Catalina 22 fixed keel

    Catalina C-22 MK-II Parrish, FL. Jan 13, 2011. #7. Part of the problem might be that Catalina recommends the fixed keel boats, (fin and wing), that the keel is supported by the trailer, in fact, recommends the keel support 60% of the weight. Possible with the un-supported keel may be the cause of this issue.

  23. Swing keel vs. Fixed keel.

    Catalina C25 Eagle Mountain Lake. Apr 27, 2012. #3. The keel and lifting components must be inspected annually, and completely replaced (not the keel) every 3 years. Failure of the lifting system can result in a violent keel drop, damaging the boat and possibly sinking it. Catalina does not recommend a swinger be kept in salt water.
