Design #539 IMS 54

boat a curiously distinctive feature. The deck geometry starts with a moderate camber that carries its curvature relatively far outboard. This outboard loaded camber shape is combined with a large sheer radius to soften the edge of the deck and improve upwind aerodynamics. The hull and deck shapes are a unique blend of performance and rule optimization that results in a large, powerful boat that will handicap well under IMS.

The rig is a continuing development of our very successful no-runner, non-overlapping headsail rig first introduced to Spain and the rest of the Mediterranean on our original CAM, winner of the 2001 IMS World Championships. For this new design the mast has a bigger fore triangle and smaller mainsail in keeping with changes to the 2004 IMS rule. The mast is very tall with ample sail area to promote good speed off crowded starting lines and on the all-important first windward leg. The rig is a two-spreader, 7/8's style fractional in carbon with swept spreaders and non-overlapping headsail. The spreader envelope has been widened relative to the deck beam to reduce overall loading. The combination of curved spreaders and diagonals located aft maximizes jib LP's. The spar has been IMS optimized in terms of mast weight, center of gravity, and overall tube dimensions.

The appendages were designed to achieve the correct balance between their size, rig size and keel weight while ensuring the keel, rudder and hull always operate well together. Appendage area is generous (as typical under IMS) allowing a correspondingly large sailplan for good acceleration off the starting line. The keel is designed to permit quick changes in the amount of weight carried in it and hence the stability of the boat.

The interior is a fairly typical, modern day, IMS racing interior, meeting the minimum IMS interior regulations and providing clear open space for storing and retrieving sails. The bunk arrangement includes the required two "hard" bottom berths as well as the required two "soft" bottom berths. Additional bunks may be added in different configurations to suit various venues. An interesting aspect of the interior is the ability to
