Abstract
Analyzing and evaluating hull design is always an essential need in practice to ensure safety and economic-techno efficiency for seagoing ships, save production costs, shape well-suited hull models for series production, etc., especially in the absence of the conditions to test the model. This problem is usually resolved by the model test method. However, many actual hulls have been unable to achieve the desired seakeeping performances even after model testing. For planning hulls, this problem is much more difficult due to the complex nature of the hydrodynamics interactions that occur when the planning hulls move at high speeds. Therefore, in this paper, an analysis of the parameters that greatly affect planing hull performance by our modified Savitsky method is performed and based on that to establish a methodology to evaluate existing planing hull designs. The results of this study have also been applied to analyze and evaluate the design of a Vietnamese high-speed vessel, denoted SESCO K88, which was tested in the towing tank but has not achieved the desired speed and performances, and pointed out solutions to overcome these disadvantages.
