Abstract: An apparatus for practicing knot tying (20) includes a base (22) to which is attached an inverted U-shaped member (24). A chain (44) is connected between the arms (40, 42) of the U-shaped member. A user then uses a rope (46) to practice tying knots about the U-shaped member and the chain. The chain can also be used to affix a rope for practicing the tying of bends. Knot-tying instruction cards (48) assist in the practice process.

Abstract: This nautical buoy is used to monitor the surface projection of a deployed anchor by floating above the anchor. This is accomplished by a connecting tether-line (16) from the buoy to the trip-eye of an anchor (48) attached using a shackle (18). As the anchor is lowered using the vessel's normal ground tackle, the tether-line (16) is deployed by unreeling from the buoy until the anchor rests on the bottom. The tether-line (16) is then secured from further deployment using a tether-line restraining tab (19) and the buoy is tossed overboard so as to float above the deployed anchor. A steady or flashing, light can be affixed to the top of the buoy to identify its location in subdued-light conditions. The buoy can also assist in retrieving an anchor, while aboard the vessel, that has been fouled on bottom vegetation, rocks, and/or other debris. Retrieving the anchor is accomplished by pulling on the tether-line (16), thus applying tensional forces nearly opposite to the frictional forces fouling the anchor.
