1 HP Electric Hydrofoil

This is a simple but well made design. It's also an excellent demonstration of the performance capabilities of a one horsepower power plant. From a human powered vehicle (HPV) point of view, one horsepower is also the typical maximum output of a human being for short duration; 1/2 horsepower being a moderate sustainable output. This demonstration gives a good idea of the kind of propulsor effectiveness that can be achieved at this power level, but not knowing the exact design it is difficult to comment on whether the design is optimal. The outriggers provide good stability, but as typical with many such designs, hinder performance at foil speeds.
