The present invention provides a long-term mooring device. A support frame is provided on a dock. The dock is provided with a free guide roller. The free guide roller is wound with a cable. An upper end of the cable is horizontally connected to a spring fixed on a lower side of a cross arm of the support frame, through a free guide roller provided on the lower side of the cross arm of the support frame (corresponding to the free guide roller on the dock). The middle of the cable penetrates through an inertial induction self-locking connection joint fixed on an end of a platform arm. The platform arm is fixed on a platform. The present invention provides an omnidirectional restoring force for the moored platform through the elastic deformation of the springs to control the movement response of the platform within a certain range.

A bow stop is an apparatus that safely aids in the docking of a boat. The apparatus includes at least tone length-adjustable stopper assembly. The at least one length-adjustable stopper assembly includes a telescopic bar, a stopper tube, a bungee cord, a first cradle mount, and a second cradle mount. The telescopic bar adjusts to the length of a boat. The stopper tube presses against the front of the bow. The bungee cord retracts the stopper tube into a neutral position. The first cradle mount and the second cradle mount secure the telescopic bar, and consequently the stopper tube and the bungee cord with the cradle mount. In a preferred embodiment, the at least one length-adjustable stopper assembly is a left length-adjustable stopper assembly and a right length-adjustable stopper assembly. The preferred embodiment further includes a length-adjustable cable, connecting the left length-adjustable stopper assembly with the right length-adjustable stopper assembly.

Varying implementations of adjustable marine fender holders are disclosed, which may receive a length of rope and hold it in place so that a marine fender may be adjusted to a desired height and then fixed in place without having to untie or retie the length of rope. Holders include a friction fit feature for engaging with a nautical cleat, and a rope channel through which a rope may be passed so that a proximal end of the rope may be wedged into a set of teeth or ridges to hold the rope in place. Another holder includes a single wedged arm that may be wedged underneath a cross bar of a cleat. Yet another holder includes a collapsible friction pad that may be wedged into a cleat. Yet another holder includes a compressible friction pad that may be wedged into a cleat.

An apparatus for mooring a boat may include a mount body including a plurality of sidewalls forming a channel. A cleat may extend from a first of the plurality of sidewalls. A plate may be removably coupled to the mount body. The apparatus may include a clamping structure comprising a movable jaw coupled to a second of the plurality of sidewalls and configured to clamp the mount to a dock rail.

A subsea line clamp assembly (1) has a body (10) having an axis and a clamp member (50), assembled in segments around a subsea line (3), and tethered to a subsea anchor (5). The clamp member (50) is movably located within the body (10). The inner surface of the body (10) and the outer surface of the clamp member (50) have respective tapered portions as part of teeth (32, 72) arranged to inter-engage. Adjacent teeth (32, 72) may be separated by axis-parallel portions. The clamping force on the subsea line (30) can be maintained at a consistent clamping force throughout the service life of the subsea line (3), despite the actions of creep and compression acting to reduce the outer diameter of the line (3).
