Abstract: A rigid U-shaped structure sized to be closely received on the tip end of the transfer hook. One side of the U-shape of the structure is closed. A padeye is rigidly attached to the end curved portion of the U-shape of the structure. Means for holding the U-shaped structure in position on the tip end of the hook is provided. The holding means may be threaded bores through one or both sides of the U-shaped structure that allow bolts to be threaded through the holes such that they create sufficient friction against the tip end of the transfer hook to hold the U-shaped structure in position. The holes through the U-shaped structure may be unthreaded with threaded nuts rigidly attached to the U-shaped structure such that the nuts are aligned with the holes to allow bolts to exert pressure against the tip end of the transfer hook in the same manner to hold the U-shaped structure in position on the transfer hook.
