ProBoat Westward 18 sail winch
« on: September 10, 2018, 07:38:07 pm »
Looking for some advice regarding a replacement sail winch for this boat. The original servo (PRB 3494) has failed and there are no spares available in the UK. Any suggestions to a compatible replacement would be welcomed. Thanks.

Probably not many on here are familiar with this particular boat.  Things to know are - what physical size is it and how many turns of the winch?  Knowing that will help.

To work out the turns with a dead winch, the actual travel is needed.
Measure the distance from boom fitting to deck fitting with the boom fully in and fully out, subtract the one from the other.  This is the travel.
Measure the drum diameter, multiply by 3.1412.  This is the distance you get for each turn. 
Divide the travel by the turn distance, you get the number of turns needed.
