Word in the field is that this servo has the power to pull a 4 x 4 out of a mud bog. Currently, several Marblehead sailors are using this winch and so far the comments are good. I was thinking of doing a refit on 899 at the end of the season and installing this winch. A computer radio is needed to set travel end points rather than doing it in the servo (RMG). And, the price can't be beat. https://www.hobbyking.com/hobbyking/sto ... duct=42642
There is a similar size winch of lower power available for smaller boats but that one would not be suitable in a 12.
