Let me start off by saying, I KNOW NOTHING! I recently acquired a 17' O'Day Day Sailer that was made in 1978. The boat was in beautiful shape with the exception that the sails and boom were missing. I found a boom and am now on a the mission of the sails. I drove to Michigan and purchased some real nice used sails but they were for a larger O'Day boat. I need to have these sails cut down to the proper size. Can anyone tell me or lead me to where to look to find the dimensions of the main and Jib sails? Any and all help would be appreciated. I have laid the the mast and boom out in my drive way and stretched the sails out and marked them where I think it makes sense to cut the sails, but before I do I would love to get the exact dimensions. Again all help appreciated. Thanks in advance.
