Has anyone retro-fitted the Harken Battcar system?I am thinking of putting it on my 2004 H33. If you believe the hype it would seem to be the cheapest and most efficient way to raise, lower and reef the main at all points of sail and without the potential problems associated with furling systems. The ability to fit the system without taking the mast down also has appeal. I would like to hear from anyone who has recently had experience with it.
