Windlass Concept

Asked on a forum, but I thought you guys might be interested: Greetings, I wonder what sort of over current<http://www.cruisersforum.com/forums/tags/current.html> protection windlasses have? Are they adequate? If they were, why would sailors and manufactures recommend against pulling the boat up to the anchor<http://www.cruisersforum.com/forums/tags/anchor.html> using the windlass- if the motor<http://www.cruisersforum.com/forums/tags/motor.html>stalls and the over current <http://www.cruisersforum.com/forums/tags/current.html> protection is adequate and reliable, then no harm done, right? I ask because I may have an alternative solution. What I have in mind- a mechanical means to create a constant torque windlass<http://www.cruisersforum.com/forums/tags/windlass.html> instead of a constant rpm. If there were no load on the rode, the windlass<http://www.cruisersforum.com/forums/tags/windlass.html> would spin at a constant rpm. When the load reaches a threshold the energy is stored and the motor <http://www.cruisersforum.com/forums/tags/motor.html> is then shut off. If the load on the rode is reduced back below that threshold, the stored energy turns the drum and then the motor<http://www.cruisersforum.com/forums/tags/motor.html>kicks back on. The threshold would be set below the point where the motor stalls. Should I give this more energy or am I combating a non existent problem. Thanks, Adam
