  • Structure for holding underwater projections
    Patent number: 4936240
    Abstract: A structure for holding an underwater projection projecting downward from the bottom of hull of a hydrofoil craft or the like. The projection is connected at its rear end base portion to the hull by a hinge pivotally movably rearward and held at its front end base portion in a predetermined downwardly projecting state by a breakable holder. The projection is held in this state during usual navigation. The holder breaks when a predetermined force acts rearward on the projection, permitting the projection to move about the hinge, whereby the projection is prevented from damage.
