Theoretical bases of essential seaworthiness increase and reduction of high-speed boats onboard rolling by application of wave loadings neutralizers are stated; wave loadings being the prime reason of rolling. It was proved experimentally that the most effective type of wave loadings neutralizer is wing profile lattices at-tached to the stern part of high-speed boats and that increased the attached weight – 2 times, and damping – 10 times. Comparative tests of the forced rolling of boats models in a seakeeping basin were conducted. They have confirmed high efficiency of the neutralizers in decreasing of boat onboard rolling. The structure of the left and right members of equation of boats onboard rolling with application of neutralizers is specified and their high efficiency in comparison with its traditional methods of rolling lessening was explained.
