The skeg for the elliptical rudder was not included in the final boat. A 'balanced' lay-up of strip planking and cold moulding was devised. Joel White's original specifications included painted decks, but these were subsequently changed to laid teak. The mast steps onto this framework and the keel bolts run through it too, thereby linking all the major stress loads. Instead, they experimented with nine different lay-ups which they sent to the WEST System's Gougeon brothers for testing.
Internal bulkheads prevent the bolts moving, and the cavities are filled with two-part foam.
Bruynzeel ply bulkheads. The mast is carbon fibre with stainless steel rod rigging, apart from the inner forestay which is wire, for ease of stowing. Donald is at pains to emphasise that this is not a development class, which he regards as one of the downfalls of the 12- Metres. The rigs, sails, hardware and equipment allow for no substitutions. Owners will however get to choose their own electronics.
