Designer's notes

The Cape 31 was clearly defined from the outset as a simple clean high performance One Design without constraint. Designed for one of the world's great sailing locations, we were able to optimise the Cape 31 for a combination of both upwind and offwind performance in a breeze while retaining lighter airs capabilities. Building on our experience developing fast light hullforms with the assistance of our R&D partners KND/Sailing Performance we produced a low freeboard aggressively chined hullshape that maximises form stability in a breeze, but enjoys low wetted surface when upright. The chine running forward to the bow helps produce a bow up moment at speed in the often windy swell of Cape Town.

Engineering from Steve Koopman at Composite Engineering specialists SDK resulted in an aggressive but production friendly structure that accommodates a socketed deep carbon keel fin and a powerful sail plan, developed with North Sails South Africa and set on a Southern Spars Cape Town carbon rig.

With the focus purely on performance we drew a clean ramp deck for easy operation, developed from our Maxi 72 World Champion design Alegre. The theme of simplicity is carried throughout the deck layout developed with Project Manager Mike Giles, including details such as the under deck jib sheet control system which replaces conventional jib tracks.
