Catamaran for pastime, model construction or racing in any competition rating, with induced hydrodinamic stability

摘要

A catamaran for pastime, model construction or racing with induced hydrodynamic stability, having a hull with a board (1) and a pair of longitudinally extended semi-immersible appendages (2, 3; 8, 9; 13, 14; 24, 25) arranged parallel to each other symmetrically to the center-line of the hull, the respective bottoms of which, at the bow tips (4, 5; 12, 12a; 21, 22; 32, 33) of said appendages, have mutually opposite slopes, each slope being contrary to the slope of the respective aft rest of the bottom with respect to the median symmetry plane of the hull.
