The analysis of possibilities of application of the small waterplane area twin hull ships (SWATH) as a specialty (universal) platform is performed. It is shown that the design of the specialized platform with a small waterplane area twin hull is characterized by a large number of parameters to be determined. The optimum relation selection between SWATH dimensions, seaworthiness, cost and efficiency is proposed by solving a multidimensional optimization problem with the use of special methods of searching solutions. The optimization problem of designing a universal platform is formulated. The constraints accounting on SWATH technical characteristics is produced by using the method of penalty functions. To solve the optimization problem, one of modern search methods – genetic algorithm is used. An example of solving the problem of selection the main dimensions of 25 m platform using a genetic algorithm is presented.
