ABSTRACT:
A stabilized float drum is shown having interlocking side and end walls and an upper compartment filled with a flotation medium such as closed cell foam and a lower member with a selected number and size of holes in the surfaces thereof to admit water which then acts as a stabilizing force when the float is subjected to upsetting wave action or eccentric loads. The degree of stabilization or damping is controlled by the relative size of the lower member and the size, placement and number of holes.
