ABSTRACT:
A buoyancy device has a rear buoyancy area interconnected to a pair of lateral under arm buoyancy areas by a pair of front buoyancy areas, and combining to form a simulated W-shape when viewed in a plan view. The provision of the lateral or underarm buoyancy areas function to hold the user more upright and normally higher above the level of the water when in use.
