ABSTRACT:
A water surface glide sailboat utilizing wind power propelling is disclosed wherein the sailboat includes a flat bottom float mounted on a beam at a joint having an axis parallel to the keel line of the sailboat so that the floats are further capable of rolling about the axis. The sailboat can be further equipped with a steering gear including a controlling stick connected to the joint so that the sailboat crew can control a flat bottom float and restrain the fluctuation of the flat bottom float to keep the parallel condition against water surface regardless of the heel of the boat and thereby decreasing the water resistances.
