In an earlier time i did some investigative work on the foils of HMCS Bras d’Or (FHE 400) which were made of mar aging steel and suffered from stress corrosion cracking. That motorized ship achieved very high speeds and proved the benefit of foiling. These AC75 boats have very special foils below and above decks. And there is a lot of match racing stuff goin on at 30-40 kts. Incredible really. On Fri, Feb 5, 2021 at 8:42 PM dwight veinot <dwight...@gmail.com> wrote:
