PROBLEM TO BE SOLVED: To minimize damage to a rear edge part of hydrofoils of a small hydrofoil craft. SOLUTION: The rear edge part 21b of each hydrofoil 21F, 21B for a small hydrofoil craft is formed with a flexible plastic or a rubber. Thus, even if something hits the rear edge part 21b at a land storage or on the sea, the rear edge part 21b is flexible enough not to be damaged, and the rear edge part 21b can be easily produced at a low cost by an extrusion molding. Since a large force normally does not act on the rear edge part 21b of each hydrofoil 21F, 21B, performance of each hydrofoil 21F, 21B may be maintained if it is made by a flexible material, such as a flexible plastic or a rubber.
