The original daggerboard keel was assembled over a steel plate, with multiple vertical steel stringers welded to each side. Timber fillers were then glued and bolted to the steel plate between the stringers, then faired to an NACA foil section. As launched, the ballast was an 1100kg lead bulb bolted to the bottom of the board. The completed daggerboard, finishing up around 70mm thick with a chord of 500mm, was sheathed in carbon fibre and glass. The JT Spars rig is soundly supported with twin, swept-back, 10-degree spreaders, topmast jumpers, and permanent and running backstays. By today's standards, the sail plan is relatively low aspect, although the working sail area is still generous. The emphasis is on simplicity and ease of handing. Rebb'l has a fully battened mainsail and a 120% genoa on a Profurl furler; the only downwind sail is a flat cut gennaker. Rebb'l's interior layout uses different floor and seating levels. The seating/dining area is raised on a pedestal so those seated can easily see out through the windows. Opposite, the galley floor is set lower to give full standing headroom. Going forward past the pilothouse section, the floor level drops again to give full headroom in the shower/heads compartment and forward cabin. There's another even lower floor level immediately adjacent to the
companionway to aid access into the aft double and pilot berths. The aft berth is a king size, with a mirror on the rear bulkhead making it seem even bigger. The engine, a 100hp 4JH3 Yanmar, is under the dining table, a position Edlin has used on several of his trimaran designs. This position keeps engine weight central, the shaft angle modest and allows easy engine access on all sides, when the table is lifted away. The fuel and water tanks, as well as the batteries, are all in this area, again aiding weight distribution. The keel-stepped mast is in the shower, so water leaking down the mast drains away. The interior has been finished in a stipple finish in high solids epoxy paint and re-coated in reaction lacquer, which has proved durable and easy to clean, as well as being forgiving of inevitable bumps and scratches. Unusual features continue outside. Rebb'l's working cockpit floor is set high, and I was always aware of standing on the boat rather than in it. The twin tillers mount directly on the rudder shafts, and either or both can be quickly removed to ease congestion. The box in the centre of the cockpit provides storage for drinks and life jackets, but its prime purpose is to give the helmsperson somewhere to brace his or her feet when the yacht's heeled.
