Abstract
Apparatus used to stabilize a sea-going surface vessel against pitching, heaving and rolling by means of stabilizer bodies which the vessel carries beneath it. A forward stabilizer body has a horizontal surface area in the range of from 13% to 20% of the ship's waterline plane, with its center of gravity at a distance in the range of from 0.22 L and forward relative to L/2, where L is the length between the perpendiculars. An aft stabilizer body has an area in the range of from 7% to 15% of the ship's waterline plane, with its center of gravity at a distance in the range of from 0.14 L and astern relative to L/2.
