Recreational power boats consume a large amount of fuel, with a typical thirty-foot boat yielding efficiencies of only two miles per gallon. The hydrofoil, a wing-like device that extends under the boat and lifts the hull out of the water, reduces drag and can potentially double the miles per gallon efficiency while improving seaworthiness and aesthetic appeal.
The AHS Hydrofoil E-Team developed a retractable hydrofoil system that increases the fuel efficiency of cruiser-type pleasure boats up to fifty feet in length. Retractable foils can be lifted out of the water when not in use, enabling easier cleaning, shallow water navigation, and the option of cruising in displacement mode. AHS is the first company to develop and produce a retractable hydrofoil system.
