Abstract
The invention disclosed here is an improvement to a fisherman's float ring whose flotation is normally provided by a donut-shaped inflatable rubber tube. The invention provides the float ring with redundant flotation. This is accomplished by placing a normally deflated secondary tube underneath a seat-supporting fabric which covers the tube. A pressurized gas bottle provides inflating gas for the secondary tube in the event the primary tube is accidentally punctured or deflates. In such case, the secondary tube prevents the float ring from losing its buoyant capability.
