Correct Response: B. A hydrofoil is a type of boat that includes wing-shaped vanes mounted below the hull. These vanes provide lift in the same way that an airplane wing provides lift. The lift force raises the hull of the boat above the surface of the water, greatly reducing the amount of drag, and allowing for much greater speeds. Barges (A), tankers (C), and tug boats (D) do not make use of this feature.
