Windlass #3 - A windlass (winch) can be fitted on to the sailboat in order to multiply the hand strength of the sailor, for the purpose of adjusting the sails. Pushing a button either up or down, the sails can be sheeting in or out.

Port drum was falling off. Bad wiring. 

The actuator can be a switch on the front of the unit, a remote with 2 buttons for in and out, or a joystick. 

Project: Working now. :)
