Abstract: A fastener hook for joining a flexible line to any target object capable of being engaged by a hook, and consisting of a generally planar, rigid body having a generally spiral slot of more than 360 degrees angular extent formed therein, the slot opening through an edge of the body to be engageable over the target object and closed at its opposite end, and an elongated connector joined at one end to the body member within the confines of the spiral slot for rotation about an axis normal to the body, and being connectable at its opposite end to the flexible line.

Abstract: A water ski tow assembly consisting of a semi-circular rail connected at its ends to a boat and extending rearwardly therefrom at variable angles of inclination from horizontal, a rolling carriage movable along the track, and a special rope hitch mounted on the carriage, the hitch permitting the attachment thereto of a plurality of tow ropes, and having provisions permitting quick attachment and detachment of ropes, locking the ropes against accidental detachment, and preventing entanglement of the ropes. The rail encircles the motor of the boat to prevent the ropes from becoming fouled in the propellor, protects the propellor from growing brush in the water, and insures the most desirable line of pull of the ropes relative to the boat.
