  • Patent number: 6904857
    Abstract: A device secured to a submersible portion of a boat lift to stabilize the submersible portion of the boat lift from unwanted lateral movement. Elongated pipe-like devices are attached to a submersible portion of a boat lift in proximity to a piling. The device is mounted to the submersible portion of a boat lift so that movement caused by wind, wave, or current action that would force the submersible boat lift into lateral motion will be stopped by the pipe-like device, which comes into contact with the piling before the lateral motion becomes so large as to be undesirable.

  • Patent number: 6843191
    Abstract: A device and method for raising sunken objects such as crates, small boats, vessels and ships including a platform equipped with winches to lower down a basket net and a frame supporting a cryogenic apparatus to the vicinity of the object. The cryogenic apparatus is adapted to pump surrounding water through a freezing unit to reduce its temperature to below freezing and then form a stream of overcooled water directed over the sunken object to form a layer of ice about it. The basket net contains provisions to allow its closure under the object once it is lifted off the sea floor. Once enough ice is formed, the object is lifted to the surface. On average, the capacity of the cryogenic apparatus is such that a 1 ton object can be lifted in about 3 hours. Remote monitoring and control means are provided for the operator to observe and direct the operation of the device. The device is especially advantageous in dealing with explosive objects such as old and unwanted sea mines, torpedoes and alike.
