Abstract
Method and apparatus for use in a floating vessel subjected to wave action, used to determine the proper vessel heading so that the longitudinal axis of the vessel will be positioned parallel to the direction of oncoming waves, thereby reducing the risk of capsizing of the vessel. The apparatus comprises a mass elastically suspended from a portion of the vessel structure. Observation of the direction of rotation of the mass allows the helmsman to determine what direction to steer the vessel so that the vessel remains headed into the waves.
