Abstract: A method and apparatus for providing data related to the ice breaking efficiency of a hull of a vessel as the vessel passes through ice, and particularly for providing data related to the frictional forces experienced on the hull of the vessel as the vessel passes through ice. Movable means is carried on the hull of the vessel generally flush with the hull for displacement in response to forces applied thereto as the vessel passes through ice. The displacement of said movable means relative to the hull of the vessel is determined as a manifestation of frictional forces between the hull of the vessel and the ice. The movable means preferably comprises a generally coplanar relation therewith and flush with the outer hull skin. The plate is mounted on a plate suspending means which permits omnidirectional movement of the plate at least in the plane of the hull. In one embodiment, the degree of movement of the plate is sensed by a plurality of electromagnets carried by the hull of the ship and disposed at spaced positions adjacent the edges of the plate, with the electromagnets cooperating with a plurality of electrical conductors carried by the plate adjacent respective ones of the plurality of electromagnets, the electrical conductors producing electrical signals related to the degree of movement of the plate relative to the plurality of electromagnets. In another embodiment, plate movement is sensed by displacement probes in contact therewith and arranged to provide electrical signals representing displacement.
