If I had it to do all over again, Id choose a Perryboat with a modified fin (Valiant, Tashiba, Passport, etc.) and with 'split underbody' ... for better 'performance'. A Ty37, IMHO, is well 'over-canvassed' - having all the sail area one needs to keep her 'up near hull-speed'.
Hope this helps.
This is what I was really trying to say without going there. A more modern designed cruising boat such as referenced above will IMHO make a better cruiser for most unless you want the 'traditional' look etc. then buy your boat and don't worry about the performance. Had a friend who owned and lived aboard a Tayana 37 and then upgraded to a Passport 40. He was shocked at the sailing performance difference.
So have fun and go sailing
