Abstract
Methods, systems, and devices are provided for a vessel comprising a retractable hydrofoil. The vessel can include a hull and one or more hydrofoil assemblies connected to the hull. Each hydrofoil assembly can further include a support structure and a hydrofoil operably connected to the hull via the support structure. Each of the hydrofoil assemblies can be configured to retract or extend from the hull such that the hydrofoil of each of the hydrofoil assemblies can move away or move close to the hull. During operation, one or more of the hydrofoils can be submerged beneath a water line. Alternatively, during a cruising speed of the vessel, one or more of the hydrofoils retracted from being submerged beneath the water line.
