Construction of an unsinkable trimaran, mast and rudder. The invention relates to the construction: 1st of hulls, without framing, which are absolutely leaktight; 2nd of a T-shaped mast, of simplified positioning, with return cord; 3rd of a rudder which self-locks at all angles. It consists, as for the floats, of whole panels, cut out of boards (plywood or plastic) connected by a film of araldite + glass fibre + ordinary resin: durable leaktightness. T-shaped mast, with a washer positioning it in housing A on the bridge. 3 holes T1, T2, T3 replacing the channel plates. T4 at the same level, for passage of the hand control roping C, fixed by two knots on either side. Rudder: cable CA1 locked in the Pe holes by pins, stopped in a half-crown CO. Cable CA2 locked by sending the ends back over the bar B and tying to themselves. Pe oscillates by the mobility of CA2 in the Pe holes which it passes through. Construction according to the invention enabling the manufacture in series of unsinkable boats. <IMAGE>
