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 impacting the performance of a foiling Moth. Specifically:
- the lift and drag was measured for of various home built and commercially available T-foil configurations,
- the hydrodynamic drag of a hull was measured at various displacements, and
- the aerodynamic forces (side force and drag) were measured for a hull and racks. It is hoped that this data will be useful for future designers to further push the state of the art.
