Design #533 Transpac 52

surface area while enhancing its draining properties. Our vertical transom style has been maintained to position the topmast backstay fittings as far aft as possible, minimizing the mainsail roach and topmast backstay interaction.

Advances in the deck layout are focused on a winch system designed for forestay-less gibing, where two after guys are required to be loaded throughout the maneuver. In this case, the secondary winches, by careful positioning can be used for after guys downwind and topmast backstay upwind. The mainsheet system is a 2:1 "half German" style system led aft to a single pedestal driven winch on centerline. The mainsheet grinder pedestal and primary pedestal are linked below deck to provide maximum horsepower during highly loaded maneuvers.

Hydraulic tensioning systems are in place for both forestay and "code 0" tack line. These systems both utilize through deck sheaves and below deck strops intended to position the actual hydraulic cylinders as far aft and low in the boat as reasonable possible.

Longitudinal jib tracks are combined with in-hauler systems to provide ample sheeting range along side the relatively large class required coach roof. Mainsheet traveller and other control lines are led below deck to maintain clutter free deck space.

Rig

The fairly standard 20-degree swept spreader rig has been combined a cathedral style topmast stay system to support "code 0" style upwind spinnakers. In this case the combined stay envelope has been carefully optimized to allow close sheeting of those sails.

The mast has been designed to class rule minimum weight and VCG targets. Where possible, IMS friendly mast and boom dimensions have been pursued to help ensure that the yacht can be competitive in other outside class events.
