A propulsion apparatus (8) for a water borne craft (9) which is capable of retracting into the craft (9) for efficient travel on water and capable of extending from the craft (9) for moving the craft (9) over land such as up onto a beach or over a sand bar or the like. The propulsion apparatus (8) has a belt (10, 40) which engages with the ground and maintains grip with the ground due to the force of the weight of the craft (9) upon it.
