H) Hydrofoils
A hydrofoil is a lifting surface that operates in water. Boats that use hydrofoil technology are also called hydrofoils. As a hydrofoil craft gains speed, the hydrofoils lift the boat's hull out of the water, thereby decreasing drag and allowing for greater speeds. Alexander Graham Bell and Casey Baldwin built the first hydrofoil watercraft in 1918.
