A number of years ago (before the 309 group moved to SBO) there was a 309 forum on Yahoo. This forum fizzled because of the excessive spamming on Yahoo, but may still exist. At any rate, there was a posting by a 309 owner in Australia, I think his name was Michael White, who designed and built a windlass system for his boat. His installation was well thought out, and his posting was very complete, even including CAD engineering drawings for the parts he needed to fabricate. I printed a copy of it, but unfortunately threw it out after I sold my 309 a few months ago. I'd suggest doing a search through Yahoo to see if you can find it. It would have been in the very early postings on the forum, maybe in 2007 or 2008. Good luck!
