Page 6: General
Also check weather forecast, know what you might be sailing into. LOADING Multihulls should be treated like aircraft when it comes to loading. Corsair trimarans are light, responsive craft, and due to their narrow waterline do not have an unlimited load carrying ability.
Page 7: Safety Compartment
A higher ratio is faster and safer. Always be conscious of weight and take care not to carry unnecessary items. The load-carrying capacity of the different Corsair models is listed in the back of this manual. Some overloading is acceptable for general sailing in sheltered waters, the only adverse affect being a loss in performance.
Page 8: Outboard Motor
‘geared down’ to give high thrust at low speeds. However, Corsair trimarans have a very easily driven hull and may not need such a propeller. The result can be the same as always driving your car in low gear.
Page 9: Trailering
While towing, watch for strong crosswinds. A Corsair is a relatively light boat for towing, but it still has considerable wind age. For easy, stable towing, the trailer should be balanced to have 5 to 10% of the total weight on the coupling ball.
Page 10: Rigging
5. Lift the forward end of the mast and walk aft, rolling the mast on the aft mast roller while checking that the rigging wires do not catch. Stop once the mast foot is over the pivot brackets. (C28 & C31 pivot brackets.) Copyright © 2014 by Corsair Marine International...
Page 11 Another alternative is to attach the yoke to the deck first, then fit the mast to it. 6. The mast foot is connected to the mast step as follows: (Dash/Sprint 750 MKII yoke.) (C28, C31 & Cruze 970 yoke.) Copyright © 2014 by Corsair Marine International...
Page 12 8. Position the mast raising pole on the mast in the yoke socket. Attach the wire form the top of the pole to the eye on the front of the mast, with the pole being approximately perpendicular to the mast. Copyright © 2014 by Corsair Marine International...
Page 13 During mast raising it is very important to be alert to all items of rigging lifting or supporting the mast. If any resistance to raising is felt at point, stop and check that nothing has fouled. Do not proceed until any obstruction is clear Copyright © 2014 by Corsair Marine International...
Page 14 Once initial adjustment has been done, the forestay turnbuckle does not need to be undone during normal rigging or de-rigging, only the clevis pin is removed or inserted. Copyright © 2014 by Corsair Marine International...
Page 15 Feed the mainsail head into the track on the mast and connect the main halyard. 15. Run all the halyard lines from the mast through the turning blocks back to the correct rope clutches on the aft end of the cabin roof. Copyright © 2014 by Corsair Marine International...
Page 16: Lauching
Back the trailer down the ramp until the trailer is submerged up until just past the inward bend of the side frame members (about 6 to 8’back the winch post). (Submerge trailer to inward bend.) Copyright © 2014 by Corsair Marine International...
Page 17 Always take care in strong winds while fully folded and with mast up. A combination of a fast tight turn and mast windage and weight could cause a roll over in such conditions. If in doubt, unfold one or both sides to eliminate this danger. Copyright © 2014 by Corsair Marine International...
Page 18 There is knack in unfolding of using both your foot to push on the upper folding strut and your hands to pull the top of the beam in and down. After a few tries you will find it easy to do. Copyright © 2014 by Corsair Marine International...
Page 19 Once the mast is properly supported by the shrouds, the mast raising wires can be removed. The spinnaker pole bowsprit can now be fitted or extended depending on model. Copyright © 2014 by Corsair Marine International...
Page 21: Rudder
Even with a lost daggerboard, your Corsair trimaran will still be sailable, and will still go to windward. In this case you should allow her to heel as far as possible, submerging the lee float to pick up lateral area.
Page 22: Mast Setup
(loose type recommended) available at marine stores can be purchased, and this includes hints on tensioning your rig. Rigging wire will stretch a little initially and all settings should be checked after a few sails. (C28 speeding upwind with tight mainsheet.) Copyright © 2014 by Corsair Marine International...
Page 23: Sailing
Some looseness is not unusual, but if it is very loose and visibly flopping around, you could risk losing your mast. Loose rigging, will also greatly affect the performance of your Corsair. SAILING This manual is not intended to be a sailing instruction manual, and it is presumed that all owners will have a basic sailing knowledge and skill.
Page 24 Neither of these controls are essential for everyday sailing, their main purpose being to give more efficient control over the mainsail. Both must be removed when roller furling. Copyright © 2014 by Corsair Marine International...
Page 25 23 | Page Corsair trimarans are sailed like any other yacht, the most notable differences being the response, lightness of the helm, and the low angle of heel. This ranges from an average of 5° to 10° to a maximum of about 15°.
Page 26 Now unthread the outhaul line and rethread it through the new reefing clew eye. All the controls of a jiffy reefing system are now in place, except you don’t have to tie off the Copyright © 2014 by Corsair Marine International...
Page 27: Rotating Mast Control
It will thus need to be let out when bearing off. Some racers like to fit two lines to the deck, one from each side for absolute control, but this can also be just another complication and is not necessary fir general sailing. Copyright © 2014 by Corsair Marine International...
Page 28: Windward Performance
If set up and sailed correctly, a Corsair trimaran will match the windward ability of the best mono hull racers, 20% to 30% larger. Pointing high and going fast is one of the hardest things to achieve in any boat, but with a little care and tuning a Corsair is one of the best.
Page 30: Spinnaker
The spinnaker is a very easy sail to use on a trimaran, due to the wide beam and level sailing. The spinnaker thus becomes a very practical and safe sail for family sailing, with very few control problems. All Corsair models use an asymmetric spinnaker, which are the easiest to use, and the fastest if used correctly.
Page 32: Safe Sailing Recommendations
A quick way to reduce sail, and achieve a very comfortable and safe motion is to simply drop the jib and sail under main only. Reefed if considered necessary. This avoids the need to tack the jib and the fully battened main remains docile and easy to handle. Copyright © 2014 by Corsair Marine International...
Page 33 31 | Page Sometimes when running downwind, it is better to drop the main and run under jib only. Corsair built trimarans can go to windward and tack while sailing under either jib or mainsail alone. 2. When winds are strong and gusty, and the boat is being sailed hard, then always have the sheet of the largest sail up, be it the mainsail, genoa, or spinnaker, in hand, ready for quick release.
Page 34 8. Always carry full safety gear, including life jackets, as required by U.S. Coast Guard and local regulations. (For safety, always wear a life jacket and when sailing hard. Always keep the sheet in hand ready for instant release.) Copyright © 2014 by Corsair Marine International...
Page 35: Sailing Hints
It should not be done offshore. SAILING HINTS Corsair trimarans have several unique sailing features, one of these being the ability to make continuous 360° turns in the one spot. To do this, while going to windward for instance, just tack, but don’t touch any of the sheets.
Page 36: Anchoring
The limit for racers with modern rigs will always be nose diving, though this is hard to do with a Corsair design, due to their characteristic ‘high bow’ sailing stance. The C28, for instance, at speed, frequently has the complete center hull bow section out of the water, the waterline beginning just in front of the daggerboard.
Page 37: Beaching
Cruze 970 if windy and there is still some distance to the ramp. Prior to folding, with all rotating masts, the mast raising wires must fitted. WARNING Rotating masts must be supported by raising wires before disconnecting shrouds, or mast could fall. Copyright © 2014 by Corsair Marine International...
Page 38 Take great care while folded in wind of 25 knots or more. A combination of a high cross wind and a fast, tight turn, may be sufficient to overcome the folded stability of bigger designs, resulting in a roll over. Copyright © 2014 by Corsair Marine International...
Page 39 The boat can now be pulled from the water, and when on level ground. Remember to check that it is fully winched slack in the winch wire. Tie an extra safety line from the bow eye down to the winch post, ready for de - rigging. Copyright © 2014 by Corsair Marine International...
Page 40: De - Rigging
It is important that this is done now, otherwise when lowering the mast any loose stays will tend to fall away over the boat. It also makes subsequent rigging easier. Copyright © 2014 by Corsair Marine International...
Page 41 This is to prevent them from rubbing on the deck which will quickly wear through any gelcoat or paint. On long trips it is also a good idea to pad between the wires and the mast, or remove the wires altogether. Copyright © 2014 by Corsair Marine International...
Page 42: Lifting Out
You are now ready for the road. LIFTING OUT Should there be no ramp present, then all Corsair models can be quite safely lifted in and out by the usual dockside lift, using the optional and permanent lifting Eyes.
Page 43: Unsinkability
UNSINKABILITY This is the ultimate safety feature for any boat. All Corsair models are unsinkable, being constructed almost completely in foam/glass, with multiple watertight compartments. With no heavy keel, it is therefore immune from sinking, even with all watertight compartments flooded.
Page 44: Offshore Sailing
42 | Page OFFSHORE SAILING All Corsair models have been designed strong enough for heavy weather sailing, the C28, C31, C37 and Cruze 970 have now crossed both the Atlantic and Pacific Oceans many times. However, it should be noted that they are small boats for such long offshore passages, and should only be undertaken by experienced sailors and well prepared vessels.
Page 46 Once folded, insert the beam locking pins. Repeat process with other side float. Smaller designs will fold up just from your weight on the wing net. Copyright © 2014 by Corsair Marine International...
Page 47 Now tighten the beam bolts, and start bailing. A long tubular type bilge pump is needed to do this successfully. You may initially need to wrap a rag or towel Copyright © 2014 by Corsair Marine International...
Page 48: Personal Responsibility
15 knots, with complete comfort and safety. Fortunately it is very hard to capsize a Corsair trimaran, but this can lead to overconfidence. Don’t fall into this trap always be aware that it is possible to capsize, and reduce speed accordingly to suit the conditions - just like any car.
Page 49: Technical Notes
However, bearing away throws mast to windward, speed falls off, and the motion feels much safer. This may sound odd, but try it sometime in lighter conditions to get confidence - it really works. Copyright © 2014 by Corsair Marine International...
Page 50: Heavy Helm
To avoid, always keep the leading edge of your rudder smooth and fair, and if it becomes a consistent problem then the best cure is to fix s horizontal ‘fence’ to the leading edge of the rudder about 12” to 15” up from the bottom. (Rudder ventilation solution.) Copyright © 2014 by Corsair Marine International...
Page 51: Compression Pads
COMPRESSION PADS These are fitted to the ends of the beams on all Corsair models, to eliminate any gap or movement between the beam ends and the raised pads in the hull. Do not remove, as this would cause the high compression loads in this area to be directed through the upper folding struts, which, in the case of the C24 and C31 are not strong enough for such loads.
Page 52: Float/Beam Vents
Type 316, a more expensive grade, but actually slightly weaker, does not. All three grades can be used on a Corsair, depending on the application. To avoid this staining, always wash your boat down with fresh water after every outing.
Page 53: Collision
‘target’ profile. However this considerably reduces stability, and as stated earlier, this is limited while folded. As a result, no doubt while swinging sideways, the gale force winds blew the F-27 on its side. Copyright © 2014 by Corsair Marine International...
Page 54 Also remove the wing and bow nets. These don’t have much windage, but it is surprising how much it can be in such winds. Your boat is then as safe as anything can be in a hurricane. Copyright © 2014 by Corsair Marine International...

Page 95: Maintenance & Safety Checklist
If possible, keep your boat under cover, as this will ensure the finish keeps its gloss for the life of the boat. Even the best gelcoat finish will eventually begin to fade. Polishing your Corsair Trimaran once a year will maintain the gelcoat shine and strengthen the gelcoat surface.
Page 96: Standing Rigging
 Check all beam join flanges for any sign of de-lamination or cracking. It is not uncommon to find hairline cracks in the gelcoat surface in high load areas, but continue to monitor. Copyright © 2014 by Corsair Marine International...
Page 97: Folding System
Any defects or problems found during this check should be remedied immediately. This checklist is intended as a guide only and may not cover every potential problem. Owner should always check every aspect of boat on a regular basis. Copyright © 2014 by Corsair Marine International...
