I'll Have to Draw up some Diagrams for you But basically it's a very simple systime that can be refined too tune it up to a high standard and allows flexability
1) everything revolves around 3 working parts a) a geared 100/1 motor--- b) a 3 position switch or a bob's board--- c) an endless Messenger (a piece of line half string half elastic
2) mount the motor to the underside of a hatch cover so that the shaft sticks through in to the open when the hatch cover is in place, make a capstain barrel (a small wooden drawer nob can be used)
3)I run the motor off 6volts... No speed control is needed just a 3 way switch (Forward, Stop, Reverse) I make my own switches like a bob's board fixed on top of a servo mounted on the underside of the hatch cover (Home made 3 way switch --- use 1/32"piece of plywood the size of a credit card cut a hole in the centre and glue it to the top of a servo --- on two sides of the ply glue a thin strip of brass or copper and to this attach a suitable length of wire running to the battery (1 for the + & 1 for the--)
You should know have a board with one side pos +, the centre neutral, the other side negative -- ...attach sweep brushes to each end of the servo arm and run wires from these to the motor this gives you a 3 way switch.
4) take 3 turns around the capstain with the messenger then at 90deg. cross the deck and go out through a hole in the bulwark then forward through a block on the bowsprit then back along the other side through the bulwark and to the capstain .... Attach the tacks(lower corners) of the course to the messenger and you have sail control of the fore sails...the upper yards will follow the lower yards .... For control of the main and mizzen add another capstan
