Your Bristol 45 is a nice design. It seems to be similar to the P-40 which is on my shortlist of "next boats." If I had to choose one fault in my A-35, it would be the large main which requires constant attention to keep the windvane working. Being able to adjust the center of effort would be a godsend.
