Hello James,
Like you I'm a novice in this area. I think there are two basic types :-
1. The servo winds a sort of miniature drum. The cords (sheets) wrap around the drum and, effectively, pull the sails in in one direction, and let the sails out in the other direction. From what I've been told, it can end in a big tangle if the lines are not correctly 'tensioned' (using springs etc).
2. The second type operates a sort of long lever. The cords are attached to the end of this and the sails are pulled in /let out as the lever moves from side-to-side. This type is supposed to be more straight forward for the novice.
Try posting a few photos (of the inside of the hull especially) – you'll need to set up an 'album' first. There are quite a few sailing experts on the forum that can help you further…
Good luck,
Dave
ps to get to "Albums" use the grey bar at the head of the forum page. It also has the little camera icon alongside it
