My boat came without the original mast and boom but the marina that sold it to me gave me one he promised would work. This is a dismasted boat. According to the info I've been able to find on the web, the 25.5 should have a mast 34'3" tall. I measured the one included with my boat today and the mast is 29'5". It seems obvious to me that performance will suffer if the mast is shorter than what was intended but how much of a problem is this going to be? I don't intend to race the boat just cruise but I also want to be able to make reasonable headway. Any thoughts would be greatly appreciated.
