The F-31R is an enhanced performance version of the well-proven, maxi-trailerable F-31. Like all earlier Corsair sport cruisers, the "R" version is exceptionally fast, roomy, and comfortable. In this model, however, some traditional cruising amenities have been eliminated to save weight, and a substantially larger sail plan is spread on a modern rotating rig to give the already sporty F-31 an extra jolt of adrenaline that is sure to please the true performance enthusiast. The mast is a beautifully finished carbon fiber rotating wing section developed for Corsair by carbon spar specialist Omohundro. It is 2-feet 6-inches taller than the standard F-31 mast, yet the rig overall is 65 pounds lighter. It is thus even easier to handle than the standard F-31 mast, and with less weight aloft it gives the boat an easier motion, even in chop. The sail plan is simple and efficient with a square-top mainsail, blade jib, asymmetric spinnaker, and screacher. Flown from the end of a 7-foot bow sprit, the roller furling screacher is one of the most powerful and versatile sails in the inventory and can be used to windward in light airs instead of a genoa. Interior moldings and equipment have been kept to a minimum to save weight, which boosts sailing performance. Nevertheless, cabins are spacious with standing headroom, a double bunk forward, and two single settees in the main cabin. Cruising amenities, such as a head and galley, can be selectively added. Corsair Trimarans Corsair F-series trimarans are versatile and exciting trailerable sailboats with overnight accommodations. They combine outstanding performance on all points of sail with the comfort and security of wide, low-heeling decks that make them perfect for cruising with the family. The shallow draft means any beach is just an excuse to pull in and play, and the exclusive Farrier Folding System makes trailering a breeze, offering unlimited opportunities for new sailing adventures. Corsair sport cruiser trimarans are innovative yet proven designs with a long history of careful development. They evolved from Ian Farrier's original folding trimaran design, the Trailertri 18, which was launched in Australia in 1974. Hundreds of boats were built during many years of further refinement, all featuring the designer's patented folding system. Australian sailing and sailors demanded tough boats, and these designs easily met the challenge, achieving many race victories and an outstanding safety record. Since 1986 Corsair Marine has built over 1,000 production versions of these designs, including the famous F-24, F-27, F-28, and F-31, which have proven the soundness and reliability of this concept in all types of sailing conditions worldwide. The basic design philosophy provides a safe, roomy, high performance cruiser that is not built at the expense of accommodations, structural integrity, or safety. Underwater hull sections begin with a very fine entry flowing back to a U-shaped midsection, followed by a broad flat run aft. Rocker is kept to a minimum to reduce drag and encourage planing. The sharp entry cuts through waves effortlessly, while the flat transom dampens pitching and prevents stern burying. The proven ability to handle short, steep chop without hobby horsing is an outstanding characteristic of these designs. At speed, the main hull planes early on the aft sections, lifting the bow clear of the water. The high-buoyancy floats provide incredible stability and minimize heel, making deadweight ballast or extra crew weight unnecessary. The center of buoyancy in the floats is located well forward, resisting any tendency of the bows to bury. Light to medium displacement craft with scantlings and safety factors specified on the rugged side for strength and durability, all Corsairs have been engineered without compromise and only the best materials and techniques are used. To ensure the high strength and low weight important in multihulls, Corsair pioneered new construction technology, including state-of-the-art aerospace composite techniques. Foam sandwich construction is used in hulls, decks, and other important molded parts for excellent stiffness, impact resistance, and flotation. Hand laid double-bias glass fabrics and carbon fiber or Kevlar unidirectionals are used selectively in all potentially high stress areas. Vacuum bagging is used throughout to produce laminates with an ideal glass-to-resin ratio for low weight, high strength, and consistent quality. Interior moldings further reinforce the hulls, forming totally integrated structures that give Corsairs a strong solid feel. Multiple layers of unidirectional carbon fiber reinforce the cross beams to ensure great strength, stiffness, and resistance to fatigue from cyclic loading. All structural and performance requirements are met or exceeded, resulting in light, robust craft with outstanding dependability. The exclusive Farrier Folding System is the key to convenience, safety, and easy trailerability. It enables the overall beam of Corsair trimarans to be reduced to a mere 8'2" (2.5 m) without losing structural strength or stability. Its most important safety feature is the complete absence of potentially troublesome hinges in the beams. The critical float-to-beam joins are solid, and there is no reliance placed on corrosion-prone wire braces; instead, the precision engineered solid aluminum folding struts, with glass reinforced acetal bushings and stainless steel pivot pins, actually strengthen the beams. Proven reliability and ease of use have made this the most practical multihull folding system for over twenty-three years. As well, Corsairs have modern, efficient rotating rigs with rugged stainless steel standing rigging. High-tech, lightweight carbon fiber wingmasts are available on certain models. All control lines lead aft for convenient operation from the cockpit. A roller furling boom is standard on the F-28 and aft-cabin F-31 for convenient sail handling, and all models have custom mast steps to facilitate easy mast raising and lowering using the trailer winch. Sitting low on their trailers and being of modest weight, Corsairs have excellent trailering characteristics and are easy to launch, enabling sailors to discover and explore many remote cruising grounds or participate in regattas far from home port. Also, trailer-based sailing offers significant savings in slip fees and hull maintenance, substantially reducing overall boat owner's costs. Single-handed setup and launching requires less than 30 minutes - everything is designed to get on the water with minimal effort, and no heavy lifting or assembly is involved. Corsair's are always launched folded, requiring no more ramp space than a monohull; once afloat, stability is excellent. They can even be motored while folded and will fit nicely into any standard width marina slip. Folding or unfolding a Corsair takes but a minute or two, is easily managed by one person, and is normally done while afloat. All that is required is to raise (for folding) or lower (for unfolding) the inboard end of one cross beam on each side. Little force is needed due to the folding system's carefully balanced geometry and the float's movement being mostly horizontal. The solid aluminum folding struts have absolute control over the motion and prevent flexing or racking. A stainless steel bolt on the inboard end of each beam secures the floats for sailing. The wing nets remain attached during the folding process, tensioning and detensioning themselves automatically. Folding can be done even while motoring. The helm is always light and responsive. Tacking is dinghy-like and can even be done using sails only, with the kick-up rudder lifted clear of the water. Moreover, continuous 360-degree turns are possible, helm hard over, without having to touch the sheets. When just taking it easy, speeds of 7 to 8 knots to windward - and 10 to 15 knots on a reach - are comfortably achieved, greatly increasing cruising range. Spray is to leeward, where it gets blown harmlessly away, keeping the crew dry. While monohull "sport boats" often require a crew of five or six (or more) to sail effectively, the highly stable, low heeling Corsair trimaran can achieve top performance with as few as two, making it ideal for couples. With its well-balanced helm readily accepting an autopilot, it's also practical for singlehanding. Corsairs are well-rounded yachts possessing excellent performance and handling characteristics over a wide range of conditions. Going to windward, they will point as high as most monohulls tracking straight and steady. They can tack easily with no tendency to get caught in irons. On a reach acceleration and speeds are exhilarating, especially when using the roller furling screechers. Farther off the wind, efficient and easy-to-handle asymmetrical spinnakers help maintain high velocities. Race results have proven Corsairs to be quicker than much larger monohulls going to windward, and downwind or reaching Corsairs can mix it up with 70-footers. The performance efficiency of Corsair boats has been well demonstrated in the demanding sailing conditions off Australia. The F-27 scored a spectacular victory in the 1990 Australian Multihull Offshore Championships, even though it was one of the smallest multihulls competing. The F-31 did it again in 1992, taking line honors in two of the seven races (this also was a stock standard boat fully set up for comfortable and safe family cruising). During that series, the F-31 finished 4th over the line in the Brisbane to Gladstone Ocean Race, just 23 minutes behind a 60-foot racing catamaran. Among the monohulls, Bobsled - a 67-foot, million dollar racing machine - made yachting headlines by shattering the monohull record by an hour and a half. Yet the trailerable F-31 had overtaken Bobsled, finishing over an hour ahead. Race victories and records continue to be set worldwide, including the 1993 King's Cup Regatta in Thailand and new race records in the 1993 and 1996 Swiftsure Classic in the Pacific Northwest. In the 1993 Miami to Key Largo Race two F-27s blitzed the entire fleet, averaging 18.2 and 17.9 knots for the 44 mile course. In its first National Offshore One Design regatta in San Francisco in 1995, an F-24 Mk.II lapped an entire monohull racing fleet, which included 39 Melges 24s as well as the J-35 and 11-Meter classes that had started 10 minutes earlier. The Australian rough water pedigree, along with hundreds of thousands of safe sailing miles elsewhere around the world, have proven the seaworthiness of Corsairs beyond doubt. The comfort and convenience of wide, near-level decks provide a sense of security, but perhaps the most important safety feature is the unsinkability provided by foam sandwich construction - a Corsair would stay afloat even if completely flooded.
