Sandwich construction is used through out the hull. This consists of inner and outer skins of double bias glass. This ensures a high glass to resin ratio. The outer skin is laminated with N.P.G. gelcoats and vinyl - ester resins. This ensures maximum protection against the ingress of moisture. High-density PVC foam of 25mm thickness ensures maximum panel stiffness and excellent impact resistance. Ballast, engine, mast compression and rigging loads are distributed through a massive longitudinal and transverse girder system below the sole. Six structural bulkheads are fitted prior to the hull demolding.

Ballast is an internally fitted lead casting which encases the centre board case completely thus ensuring all centre board loads are distributed through out the entire keel. The centreboard pivots on a massive 50mm S.S. pin and has a simple cable actuator it is possible for either hand or power operations). The board, although negatively buoyant, it does not significantly alter the centre of gravity. So whether the board is retracted or extended it does not effect the stability and will only be lowered for windward performance.

Deck construction is also of foam sandwich with high percentages of double bias glass thus giving high strength to weigh ratio and excellent panel stiffness. All load bearing areas eg. sheet tracks, stanchion mounts, winch pads etc., are reinforced with marine ply pads and marked clearly in the moulded traction pattern of the deck.
