Your right Mary...Picking up a clump of grass while racing singlehanded is very frustrating. As was mentioned earlier the boards are no problem for us H17 sailors. If you have to dump the main to unload the rudders, go to the back, raise and lower a rudder, you can loose a lot of ground. I do the following: First keep a sharp eye on the water ahead and try to dodge the clumps. If I do pick up a clump and I'm considering a tack anyway, I tack and hope it will come off. If its on the weather rudder I try to fly the hull to get it to drop off. Downwind I use only one rudder. Otherwise I just take the hit and go back and clear it...Dan
