Hi again Chris, correction to above, the winches I have in the Comtessa and Fisher are more powerfull than neede for the Comtessa. Ref Comtessa instructions.
Neither Servo Shop nor CMB seem to have a winch in stock. Krickshop in Germany and aslo Graupner.com have sail winches but they are not cheap. They don't send direct to Norway because we are not in the EU, but they may still send direct to UK.
The advantage of these units for the Comtessa (and SOME other yachts) is that there is no need for spring tensioning of the sheets to each sail as the winch drum is enclosed and the sheet line cannot fall off the drum. Even with a winch mounted sideways the sheet will not stay on an open drum (ie. Hitec winch) without tension.
There may be some sailers on the forum who can offer a solution to this -or even know of another servo with an enclosed drum. Not sure if I have close-up photos of in the Comtessa or Fisher albums but I probably do.
You can see the Graupner 5217 on http://www.graupner.de under "servos" then "boat servos". This is more powerfull than you need.
I'm ranting on a bit now, but for info' the mizzen sail on my Colin archer will be operated by a 4-turn Krick winch titled 1004MG. This does 4 turns which is probably OK for the Comtessa.
I see now that the winch in the instructions is the 1006MG which has 6 turns. article nr. 79073 This costs 28 Euros. They are in stock at http://www.krickshop.de
Phew…
