Abstract: A sailboat apparatus includes a hull having a bottom, bow and stern portions along with a central portion and at least one mast for supporting a sail extending above the hull. The mast is mounted to the hull for side-to-side movement relative to the hull. A keel assembly has a keel extending below the hull bottom and through the hull bottom and attached to an elongated transfer shaft rotatably mounted to the hull and having the mast coupled to one portion thereof. The keel is coupled to another portion of the transfer shaft and extends from the transfer shaft through the hull bottom into the water so that movement of the mast from side-to-side rotates the transfer shaft and the keel in the opposite direction from the mast to stabilize the sailboat.

Abstract: A recoil reducing device for a firearm including a hollow sleeve received within a chamber of the stock of the firearm, with one end directed toward the receiver of the firearm and the other end directed away from it and with closures at opposite ends of the sleeve. A pair of radially projecting lugs externally position the device and space the sleeve within the chamber. A weighted piston is slideably received within the sleeve and biased into a central position therein by springs on opposite ends. The piston is provided with a lubricant reservoir and means for permitting the lubricant to flow from the reservoir to the outer surface of the piston. Further, the closure at the sleeve end directed toward the stock is provided with an outer face presenting closely spaced teeth at equal angular intervals for establishing a predetermined angular orientation of the device within the chamber.
