A NEW INHERENTLY STABLE SURFACE PIERCING FOIL SYSTEM: A BREAKTHROUGH IN SMOOTH SEA PERFORMANCE

The author of this treatise developed a new inherently stable and uncomplicated foil system with the object of reducing uncomfortable wave-impacts to which passengers on a craft with surface-piercing foils are subjected. For experimental investigation a front foil for a 1.7 ton boat was built and tested. With this foil lateral accelerations were reduced to less than 30% and vertical accelerations to 40% of those occurring with the conventional Schertel-Sachsenberg system under the same conditions. This means that the ride in a seaway, in which impacts were formerly experienced as uncomfortable, will be now, according to human sensitivity criteria, noticeable but without unpleasant sensation. Many other advantages are attained over the conventional surface-piercing foil configuration. The progress which is achieved with this economically operable system will contribute to the expansion of applicability and popularity of the hydrofoil in general.
