Abstract
A buoyant body with a spherical hull having a well extending along a vertical axis. The well is open at both ends to permit flow of water therein and is such dimension as to make the period of its vertical oscillation greater than the period of vertical oscillation of any waves of significant height reasonably expected to be encountered by the body. The body is otherwise weighted so as to be tuned against roll oscillation.
