  • Patent number: 5902162
    Abstract: This aquatic sporting device can be used by paddlers of water crafts or boats to paddle their craft or alternately use their paddles as quick-action squirt guns or water cannons with high range and high water exchange rate. The ridged paddle is transformed into a squirt gun by hand turning a nut on the paddle shaft to free the movement of a piston within the paddle shaft, inserting the bottom end of the paddle into the water and then pulling on the paddle handle to draw a central piston several feet out of the outer paddle shaft thereby creating a suction which draws water into the paddle shaft through a nozzle at the bottom end of the paddle blade. The paddle is lifted out of the water and pointed toward the target then the handle is pushed causing the piston to forcefully squirt the water, within the paddle shafts' water chamber, out of the nozzle. The squirt gun can be switched back to paddle mode by pushing the piston back into the outer shaft and re-tightening the central nut.

  • Patent number: 5740751
    Abstract: It is common practice for pleasure boaters to moor their craft to fixed and buoyed moorings by securing a line from the vessel to a ring attachment on the mooring. To accomplish this normally requires one person standing at the bow to capture the ring on the mooring with a boat hook and lift the mooring ring sufficiently so that a line can be passed through the ring and secured to the boat. This procedure has to be performed from a height of one to three meters above the water and sometimes can be hazardous.With the present invention, the mooring procedure can be performed with increased safety and with a single action by utilizing a hook mechanism comprising a rigid body and a spring loaded detachable arm attached to a common extension pole and used to pass a line through a continuous ring and recovering said line. The rigid body has guided cavities incorporated at specific locations within the rigid body to receive the detachable arm.

  • Patent number: 5292160
    Abstract: A rope retriever device for passing a rope around an object, such as for mooring a boat. The device has a U-shaped member and a pivoting member that functions to pass a rope behind an object and back to the user. The end of a rope is held in a rope holder on one end of the U-shaped member. The rope is laced across the mouth of the U, around a pin on the pivoting member, then back to the user. The rope retriever can be activated by pushing the device against an object or, alternatively, by manually pulling on the free end of the rope. Tension in the rope causes the pivoting member to pivot across the mouth of the U until a spring clip on the end of the pivoting member clips onto the end of the rope. When the device is withdrawn, the pivoting member passes the rope around behind the object and back to the user. The device can be mounted on the end of a long pole or attached to the end of the handle on a boat hook so that it can be used for passing a rope around objects that are out of reach.
