RE: vacuboats
Phil was at our regatta last September with his boats. I didn't know who he was at first until the last day of the regatta, real nice guy. Got talking to him about his boats and all the parts and pieces. What impressed me was his version of the Dumas dogbone drive. It has 4 nubs on either end vs. Dumas' 2 nubs. It is self centering, runs quieter, stronger and cheaper. He had to leave to get back home so the 2 hours that we talked was cut short. Great guy.
Hope he comes back again this year.
