<p>The hull has two lateral floats (1,2) connected by a central platform (3) on the upper sides. The lower surfaces of the floats (7,8) are concave longitudinally and laterally. The height of the floats diminishes towards the rear. The drive has two propellers (4,5) on either side of the longitudinal axis and independently actuable. The floats can be shaped to allow stacking of the hulls one on top of the other. The propellers can be actuated by pedals.</p> |
