I just bought a 1982 Hunter 33 and it needs a new main. There have been no modifications done so it's should be a pretty standard measurement (I know that's almost a sinful thing to say). I've never had to order a sail but I've been googling a lot. Here are some measurements I've seen and I'm looking to see if anybody believes that these might be pretty standard or not....
