A device for securing a rope or cable that may be easily mounted to an object or supporting structure. The device includes a base having a socket for receiving a plunger. A coil spring is located at the bottom of the socket and exerts an upward bias against the bottom of the plunger. Both the upper portion of the base and the plunger have circular apertures that may be selectively vertically aligned by depressing the plunger to permit horizontal passage of a rope through the aligned apertures. By releasing the plunger, a shearing force is applied to the rope due to the misalignment of the apertures, thereby frictionally securing the rope or cable within the device. A foot operated mechanism may be employed to assist the user in depressing the plunger. The plunger may also be selectively and/or releasably locked in a depressed position to maintain alignment of the apertures, facilitating insertion of the rope without the need for maintaining a downward force on the plunger.

A pair of stern thrusters for a vessel, comprising: a. the vessel having a bow and a stern, and the vessel further having a horizontal platform mounted aft of the stern, b. the stern thrusters being mounted on opposite sides of a longitudinal axis of the vessel to provide thrust perpendicular to the longitudinal axis of the vessel for vessel maneuvering; each stern thruster having the following features: c. a waterproof power unit having a longitudinal axis; d. at least one propeller mounted to the power unit along the longitudinal axis of the power unit; e. a linear deployment device to raise and lower the waterproof power unit and the propeller, a hollow support pipe to connect the waterproof power unit and the linear deployment device; f. the power unit using direct current which is delivered to the waterproof power unit via a flexible line which extends through the hollow support pipe; g. the linear deployment device mounted directly above and to the horizontal platform and above the vessel waterline allowing the waterproof power unit and propeller to be raised above the waterline when not in use and lowered into the water when in use.
