Joe,
My first board was Mistral also I had a Maui second board was also a Diamond Head. They both got me to where I am today. An answer to your question about Peter Britton “where is he today?” He sold the shop to Dan Scorza in the 90’s and went to work for Xerox.
I’ve seen him 3 times in the last 2 weeks I’ve come to find out he has moved just one street from me and yesterday he was out for a walk with his wife and I waved as he went by my house. He still sails from time to time. However more importantly he went to Hatteras for a long weekend with a bunch of other Rochester windsurfers last month to take kite boarding lessons.
