... NACRA 17 is a small foiling catamaran used in Olympic sailing. Sailing in the NACRA 17 is truly unsteady, especially in the foiling conditions. Dynamic velocity prediction has gained a lot of attention in recent years due to the unsteady nature of foiling sailboats. Different approaches have...

... Foiling yachts and crafts are both very sensitive to the flying height in terms of stability and performance, raising the scientific issue of the influence of the free-surface when the foil is at low submergence. This work presents numerical simulations of a 2D hydrofoil section NACA0012 at 5...

... Hydrofoil supported sailing vessels gained more and more importance with in the last years. Due to new processes of manufacturing it is possible to build slender section foils with low drag coefficients and heave stable hydrofoil geometries are becoming possible to construct. These surface...

... was tested in a conventional configuration at various leeway angles with the foil aligned to the center plane, in a gybing configuration at a series of angles relative to the hull, and in configurations combining hull yaw and gybing angles to simulate realistic performance. Side-force (lift) and resistance...

... The International Moth class has experienced a resurgence of interest and publicity associated with the adoption of hydrofoils and the performance improvements these foil have brought. This paper documents a series of full scale tow tests intended to characterize some of the major parameters...

... forward speeds and small angles of attack. It is shown that there are two contributions to the lift and drag on the foil, one due to the vorticity shed into the wake and another due to the port/starboard asymmetry of the radiated wave field. The mathematical problem is specified as a linearized boundary...
