Abstract: 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.

Abstract: The present invention provides an improved device for attaching a watercraft to another structure such as another watercraft or a fixed structure, such as a dock. The apparatus comprises a spacing bar and specialized, quick connecting and releasing attachment devices that allow the watercraft to be quickly and effectively moored to other structures on the water without the risk of collision or damage to the watercraft. The quick-connect devices may be positioned near ends of the spacing bars to effectively hold the watercraft at a predetermined distance from the other structure. The device may further include tensioning mechanisms that are operable to keep the spacing bars at a substantially orthogonal orientation relative to the watercraft to maintain the pre-determined spacing between the watercraft and the other structure.

Abstract: An apparatus is described for fixing floating bodies (1), in particular boats, to a landing body (2) with at least two holding booms (5) which are fixed to respective mooring means (4) by means of fittings (3) functioning as coupling elements, in each case at one end on the floating body (1) and at the other end on the landing body (2). In order to create advantageous conditions, it is proposed that at least one of the holding booms (5) be fixed, at least at one end, to the respective mooring means by the fitting (3) functioning as a coupling element so as to be rotationally fixed or rotationally resilient about an at least approximately vertical axis (7) with an adjustable and fixable angular offset (?).

Abstract: A system is provided for rigidly attaching a supply ship to a receiving ship to facilitate efficient transport of materials there-between even when the vessels are subject to heavy seas and weather. A telescoping truss assembly is provided on the first ship, and has a distal end configured to mate with a receptacle assembly on the second ship. Cables are disposed within the truss and are used to draw the truss and receptacle assemblies into engagement with each other. Once the assemblies are engaged, a hydraulic system is used to draw the two ships together, rigidifying the truss assembly and fixing the two ships in a “catamaran” arrangement. Subsequent transfers of materials between the ships can be carried out without the need to compensate for the relative dynamic vertical and horizontal displacements between the ships due to wind and waves.

Abstract: An apparatus as described for mooring to floating vessels (10, 12) side-by-side. The first vessel (10) is moored to the seabed by a single point mooring system (14). The apparatus comprises an arm (20) with proximal and distal ends. The arm (20) is mountable on the first vessel (10) for rotation about a vertical axis and the distal end projects outwardly from the first vessel (10) in use. A substantially inelastic mooring line (24) is attached to the distal end of the arm (20) and is securable to the second vessel (12). The resilient means (26, 28) is operable to allow limited rotation of the arm (20) about the axis in the first direction in response to tension in the mooring line (24) which exceeds a pre-determined value. The resilient means automatically restores the arm (20) to its former position upon reduction of the tension below the predetermined value. The arm (20) is freely rotatable about the axis in a second direction opposite to the first direction.
