TL;DR: In this article, the impact of interceptors on the performance of an Open 60 yacht hull was investigated, with a marked reduction in calm-water resistance over a wide speed range, with benefits of 10-18% in the speed range between 8 and 20 knots, accompanied by reduced sinkage and trim.

TL;DR: In this article, a parametric analysis of the trends in the aerodynamic forces is performed on a simplified vehicle model, and new designs for aerodynamic drag reduction, based on the combined effects of the different parameters investigated, are proposed.

TL;DR: In this paper, an in-house code was developed based on the boundary layer similarity law analysis for the prediction of the increases in the frictional resistance coefficients and effective powers of ships due to the use of a range of coating and biofouling conditions.

TL;DR: In this paper, the impact of interceptors on planing craft hydrodynamic quality is investigated through application of an experimental method and two scaled-down models of high-speed planing mono-hull and catamaran are tested with and without interceptors in calm water at different heights of the interceptors to investigate the effect of interceptor on drag reduction of the models.
Abstract: Trim control mechanisms such as interceptors and trim flaps have been widely used in recent years in highspeed crafts for ride and trim control. In spite of their extensive application, a few studies investigating the impact of interceptors on planing craft performance, have been published. In the present study, the impact of interceptors on planing crafts hydrodynamic quality is investigated through application of an experimental method. Two scaled-down models of high-speed planing mono-hull and catamaran are tested with and without interceptors in calm water at different heights of the interceptors to investigate the effect of interceptors on drag reduction of the models. The first one is a scaled-down model of 11 m planing mono-hull boat and the test was conducted at the towing tank of Sharif University of Technology, Iran. The second one is a scaled-down model of 18 m planing catamaran boat and the test was conducted at the towing tank of Krylov Shipbuilding Research Institute (KSRI), Russia. The experimental results show a remarkable drag reduction of up to 15% for mono-hull model and up to 12% for catamaran model over the wide speed range of the models.
