You sure about Watts not being a Brit? If I recall he was formally trained in meteorology by the RAF, and after retiring from service started discussion and/or racing sailboats with his brother, prompting his book. Probably written in the 40's or 50's? You're right, the original is the one wanted, I had an opportunity to read a copy prior to a NAC campaign in the early 90's. The book was promptly returned to my skipper as it was considered a family heirloom, had been passed down three generations.
