The watercraft has an inclined passage, and a single or double floating structure (2) on which a wheel chair (1) e.g. electrical wheel chair, is fixed. The structure has paddle wheels (3) activated by circular handrails (4) located in vicinity of wheels of the chair. The paddle wheels are driven in rotation by the rotation of the handrails by a cylindrical axle (5). A space adjustment unit adjusts the space between the handrails. Four ferrules (6) are partially submerged to maintain the paddle wheels and form a anti-drift surface. Retractable rollers are located under the structure and a hull. |
