This invention relates to a water buoyant garment such
as a buoyant swimming garment in conjunction with
sailing means coupled to the garment, whereby the wearer
may be propelled through the water.
Generally speaking, most buoyant water garments com

In essence, my water garment sail-float combination
comprises a single substantially rigid panel having an el
