Thanks, all, but I think it is impossible. Picture this: You're singlehanding a Taipan 4.9 in a distance race on Biscayne Bay. You are out on the trapeze. You are steering and handling both a mainsheet and a hooter sheet. You need to clear grass off your leeward board and rudder. What conceivable way would there be to do that without coming in off the trapeze, heading up and basically stopping the boat? And you have to repeat the procedure very frequently.
