Model of a Slip Hook for Lifeboats, Petrus van der Loo, 1857 demonstration model Wooden model of a slip hook, painted gray, consisting of two parts: a Kram, which is fixed with an eye in the floor of the boat, and a key with an eye for the hoist of the davit and a thick end. This can be done through the opening of the Kram, which is reduced by a thicker leg of the Kram; But a bracket around the other leg reduces the opening even further and clamps the key. Only when the boat is in the water and the tension of the hoist is gone, this bracket falls due to its own weight and the key is released.
