<p>A rowing boat has a hull (10), a seat (12) for an operator and an associated rigger (17) and stretcher (18). The seat (12), rigger (17) and the stretcher (18) are movable relatively to one another fore and aft as the operator rows. The hull (10) has a hydrofoil (21) for raising the hull (10) above the water as the boat is propelled by the operator. The position of the centre of gravity of the boat and operator is maintained generally constant relative to the hydrofoil (21). <IMAGE></p> |
