An apparatus for testing a mooring bollard is disclosed. The apparatus has first and second connector ropes for attaching the apparatus to a pair of bollards. There is also a pulling device (such as a hydraulic ram) for applying a pulling force to the bollards via the connector ropes. The device further includes a pulling force measuring device connected between the ram and one of the connector ropes, for measuring the pulling force being applied between the bollards. Finally there is a computer system for controlling the hydraulic ram and for gathering data from the data measuring device.

A tube guide assembly for mounting in a rod holder of a vessel. The rod holder has a depth from a cross member to a top surface. The assembly secures a mooring line to the vessel. The assembly includes a tube having a longitudinal axis and a base end dimensioned to be disposed in the rod holder to engage the cross member. The tube has a second end opposite the base end. The second end has a cleat to secure the mooring line. The tube has inverted J-shaped slots opposite one another to receive the cross member therein. A spring-loaded lock assembly is disposed in the tube. The lock assembly has a plunger to press against the cross member and lock the cross member in the J-shaped slots.

A sonar device including a tow cable and a towed body elongate along a longitudinal axis from a first longitudinal end to a second longitudinal end. The towed body includes a plurality of electroacoustic transducers aligned along the longitudinal axis and is connected to the tow cable, so it is able, when it is towed and fully submerged, to be oriented along a vertical axis. At least one towed body is connected to the tow cable by a first hanger and a second hanger. First ends of the first and second hangers are connected to the tow cable and a second end of the first hanger is attached to the towed body at a first fixing point near the first longitudinal end and a second end of the second hanger is attached to the towed body at a second fixing point near the second longitudinal end.

A docking system has vertical rails and brackets for securing to a lock wall. A floating structure has a series of aluminium tubes each extending through multiple resilient buoyant element. Carriages on the tubes engage the rails, the carriages allowing the floating structure to rise and fall on the vertical rails according to water level. Bollards extend inwardly to the dock wall at spaces of several meters. A boat such as a leisure barge can enter a lock without need to tie to the dock, the floating structure protecting the barge as it rises with rising water level. It therefore allows safer and simpler passage of craft through locks, especially leisure craft manned by inexperienced people.

Protective polymer covers for metal equipment are disclosed. The metal equipment is generally used with wire ropes, and the protective polymer covers provide a smooth protrusion free surface which is suitable for contact with a synthetic line. The protective polymer covers are shaped to conform to an outer peripheral surface of the metal equipment, and include at least one cover section having at least one means for connection at each of a first end portion and a second end portion. The protective polymer covers are composed of a thermosetting cast polyurethane having a Shore D hardness of greater than about 60 or a Shore A hardness of greater than about 85.
