Fendercare Marine provides a range of Sea Catch products to enable safe release under load.
Sea Catch products are widely used and trusted worldwide as the simplest and innovative quick release hooks available. Sea Catch uses the proven toggle linkage principle to both lock and release lines or objects under load. Models range from 1 to 600 tonne capacity.

The LM series up to the TR12 have an enlarged and reinforced jaw area able to accept larger diameter wires and shackles than the standard Sea Catch.
The TR15LM is a modified TR15 provided with a front jaw enlarged to receive up to 2.98" fibre line such as a fibre forerunner. Additional side plates at the jaw area are provided to spread the load. An inner jaw radius of 1.61 inches is formed to simulate the synthetic line end of a Mandal Fairlead Shackle #120M.
The TR15DM is a modified TR15 provided with a front jaw enlarged to receive up to 3.3" fibre line such as a fibre forerunner.
Additional side plates at the jaw area are provided to spread the load. An inner jaw radius of 1.61 inches is formed to simulate the synthetic line end of a Mandal Fairlead Shackle #120M.
Standard Sea Catch units are fitted with a hole in the body below the release lever and mounting holes tapped in the base of the body.
The rod end of an air cylinder is inserted into the hole and the cylinder is mounted below the body with thru-mounting screws. Air-activated Sea Catches operate at 60 to 100 psi. Manual backup release is maintained by means of the standard lanyard pull on the release lever.
The Sea Catch RAM hydrualic activated unit is a standard Sea Catch model fitted with a hydraulic cylinder mounted below the device.
Above the cylinder is a plunger which penetrates through a hole in the body below the toggle pin. When activated, the cylinder pushes the plunger and the toggle pin upward causing the Sea Catch to release. The usual manual release capability is maintained. The maximum hydraulic pressure for all hydraulic cylinders is 5,000 psi.
Sea Catch Squib-fired models are standard Sea Catch units fitted with chambers below the release lever where a squib or squib-fired thruster is threaded or inserted and secured. The units are electrically, often remotely activated.
The Sea Catch TR5SQ and TR7SQ can now be fired solely with a squib although the use of squib-fired thrusters offers far greater dependability, firing consistency and safety. With the TR5SQ and the TR7SQ, safe, split second release activation is provided for both single load or multiple load releasing. Manual backup release is maintained by means of the standard lanyard pull on the release lever.
The Sea Catch TR7RL is simply a Sea Catch TR7 with a release lever that is reversed.
This modification allows the operator to activate the unit from the side of the unit (perpendicular to the line of load) or slightly below that direction. Special care must be taken to stay clear of objects being released under load.
