The present invention is for a recreational water vessel that may by operated driven by a manually operated propeller and drive system or it may be driven by wind under sail. The vessel includes two boards mounted to a main frame. Each board has a concave shaped bottom surface and an inner side surface that is vertically disposed with respect to the surface of the water. The drive system operates two propellers simultaneously and/or independently. A key mechanism may be biased between a position to operate the propeller simultaneously and independently. The vessel has a mast that is mounted toward the rear or stern of the main frame. A boom is mounted forward of a seat. A sail has a top mounted to the mast and a clew mounted to the boom. The sail is triangular such that a fold extends from the boom to the mast forming two halves of the sail.
