Hello friends, I am I'm need of some used sails for my o'day 20 year 1977. I am currently set up with hobie 16 mast and sails. I retrofitted the mast with spreaders and re-rigged the whole boat however the sail area is a bit over. The 1977 I believe had a 27' mast and was rigged as a fractional. My mast is 26.5 so it should work or if I found sails from the masthead sloop I could cut it down. What are your thoughts. Thanks, Scott
