Abstract

A method of propelling a light craft forming an alternative to rowing incorporates in the hull of the vessel, which may be an amusement type craft, a container immersed in the water, with a flap one end controlling the flow of water through it, the flap being operated by to and fro movements of the user, similar to rowing, so that water is alternately trapped and released. Alternatively, instead of a rectangular container with a flap, a bellow type container may be used.
