Abstract: A buoyant rescue device for retrieval of drowning victims, particularly those that have fallen through floating ice, in the configuration of a catamaran with an opening in the bow to allow a ladder structure to rotate into the water. The ladder is pivotally mounted to the center of the craft and is lowered into the water the so the victim can climb the ladder onto the craft, or if the victim is injured or too weak to do so, a rescuer can provide a downward force at the top of the ladder and lift the victim out, such as a teeter totter would operate. The centrally located pivot point alleviates most of the listing or tilting and potential capsizing that would occur if a person were to climb onto the edge of the boat or if rescuers were reaching into the water to retrieve the person.

Abstract: An exterior hull patch and method of use for covering and containing leaks due to hull damage to ships, vessels and barges that has a flexible material center surrounded by an inflatable border or perimeter. The patch is positioned over the damaged area and then drawn tightly against the hull of the vessel via cables that are routed to both sides of the vessel and under its hull and attached to the patch perimeter as well as to winches or similar devices onboard the ship. Once the patch is relatively snug against the hull, the inflatable boarder is inflated with compressed gas to increase the pressure against the hull and leak, thus sealing the leak. This prevents the vessel from sinking as well as prevents liquid cargo to be lost.

Abstract: A man overboard retrieval device where a frame supports a net and rollers. The frame is secured to a handle. The frame includes a hinged arm.
