I would like to be able to lower my sails while on the water for reasons like reefing, being towed, drifting and relaxing, fixing a batten, etc.

My boat is a '75 with the clip at the mast head. As far as I can tell it would almost be imposible to deal with on the water.

Is there a system that would make it possible to lower the main while in the water?

I posted this on the Hobie site so sorry if you have already seen it.
