Cable winches are delivered in different types and with different
capacities; low-pressure hydraulic, high-pressure hydraulic and
electrically driven. Choice of winch is dependent on prevailing
conditions; type and length of cable and available source of power.
Most types operate automatically - the cable is pulled out, kept tight
during towing, and hauled in together with the trawl. Control of the
winch is done remotely from the bridge.
Any commercially available pulley block may be used to properly
align the cable onto the winch. A snatch block has the advantage
that it may be installed without having to thread the cable through
it. A unit with two movable steering arms (one on each side of the
pulley) is recommended to prevent the cable from coming off the
pulley and causing damage to the cable.
