A NOVEL APPROACH TO IMPROVEMENT OF FAST CATAMARANS' SEAWORTHINESS

The author's analysis of present-day transportation systems, undertaken to identify areas of their preferential application, substantiates the feasibility of the construction of fast catamarans whose hydrodynamic arrangement assures superior seakeeping performance. It is shown that such catamarans can be certain of a satisfactory niche in the worldwide fast boat market through optimization of their hydrodynamic arrangement and development of a special system of passive stabilization and pitch and heave moderation. The physics of the approach to reduction of pitch, heave and specifically vertical accelerations in the ship's bow is clarified in detail. The procedures and results of towing tank model tests which were carried out to assess the seaworthiness and rough- water performance of the catamaran design are described. Ways to improve the arrangement are identified and discussed.
