Yeah...but he has a theory that diesel exhaust soot is a long chain polymer which could reduce the friction of the Wave hull through the water!
Actually, that is my theory. I passed it on to Rick, and he embraced it enthusiastically, because it gave him a good excuse not to wash the boats.

P.S. We have been hoping that we won't get protested out of a regatta for having the long-chain polymers on the hulls.
