Heavy Duty Snare
Note:- In the US a large portion of aluminium boats have an eye bolt like the fibreglass boats, so the fibreglass snare is the choice.
This unit can be used on both Fibreglass and Aluminium boats. In the case of aluminium you need to have plate weld in for mounting. Only intended for large boats.

This uses a piece of stiff plastic tube - see details here.
