A board including a contact section, and a first step section which is at a different height from the contact section so that it does not make contact with a substantially level water surface when the board is at rest on the top of the substantially level water surface. The board further including a first hydrofoil fixed to the first step section. The first hydrofoil includes a keel and the first hydrofoil is fixed the first step section so that the keel is substantially perpendicular to the board. The first hydrofoil includes a wing which is fixed to and substantially perpendicular to the keel of the first hydrofoil. The wing is angled relative to the first step section from zero degrees to ninety degrees. The board may include a second step section and a second hydrofoil, which may be fixed to the second step section. |
