Seakeeping, Hydrodynamics

Paper

Full scale seakeeping trials are rare, especially for planing hulls, and are in general focused in studying bottom pressures, accelerations and vibrations. In this paper, a comprehensive description of the experimental setup and analysis of full scale seakeeping trials propulsion data of a 65 ft planing pleasure yacht is presented.
Torque and rpm have been measured on both propeller shafts...

12. Numerical Modelling of a Planing Craft With a V-Shaped Spray Interceptor Arrangement in Calm Water

Seakeeping, Hydrodynamics

Paper

V-shaped spray interceptors, also referred to as spray deflectors, are a novel concept of spray deflection on planing craft. Conventional spray rails are positioned longitudinally on the bottom of the hull and detach the spray from hull deflecting it towards the sides or slightly down and aftward. The V-shaped spray interceptors, on the other hand, are located in the spray area forward of the...

Seakeeping, Hydrodynamics

Paper

Hydrodynamics of High Speed Craft is a topic of very high interest for recreational boaters and industry professionals alike. This project aims to be a first step toward conducting such experiments in exposed outdoor environments. This paper will outline a preliminary design and testing plan of a free running model of a high speed craft. The proposed free running model will be subjected to all...
