Sea Catch is a revolutionary line of quick-release hooks designed for the heavy-duty maritime industry. Unlike standard hooks, Sea Catch uses a patented toggle-linkage mechanism that allows a load to be released safely and reliably even while under extreme tension. This makes it an essential tool for towing, anchor handling, fast rescue craft deployment, and heavy-duty lifting.
At Anchor Express, we stock a wide range of Sea Catch models, from the compact TR3 to the massive TR10, catering to professional mariners who prioritize mechanical precision and safety.
1. Why Sea Catch? The Toggle Release Advantage
The genius of the Sea Catch design is its simplicity and reliability in high-stress marine environments.
-
Release Under Load: Designed specifically to release objects or lines while they are under full tension with minimal effort.
-
No Springs: There are no internal springs to rust, lose tension, or fail. The mechanism relies on mechanical leverage.
-
Multi-Directional Release: Can be tripped via a lanyard from almost any angle—perpendicular or parallel to the load.
-
Safety First: Every unit features a hitch-pin safety lock to prevent accidental release during transport or rough seas.
