For a very long time I figured that the following rules would be exiting.

Externally powered winches and such are allowed when the inputted energy is derived fully from the boatspeed, windspeed or wave action.

The accumulation cells have to be "effectively flat" 1 min before the start. (implying they need to be charged first before they can be used to drive winches)

I'm looking forward to either human grinders charging the cells or having a small outboard propeller do it when the boat is propelled through the water. Solutions can range from pressured gas systems, spring systems to electrical setups. Either way the solution is completely green and in the spirit of sailing where all energy is derived from the interaction between the craft and the wind and water.

Anybody has a line to the rule writers ? And is willing to shot off an e-mail to them ?
