... Towing tank tests were carried out on three slender models in order to obtain more information on the hydrodynamics of such shapes, and in particular, how the shapes could generate side force when operating at a leeway angle. Slender hulls are of much interest for multi-hull vessels...

... of an A-Class catamaran is simulated by using the RANSE software FineMarine with its volume of fluid method. The C-shaped hydrofoil is analysed for one speed at Froude Number 7.9 and various angles of attack (AoA). The rake was defined and a leeway angle was applied to simulate realistic set ups...
