So I bought my first sunfish last weekend It has a new north sail that says racing, however I've read racing sails are only white and have a window? The boats is 170lbs so I have a bit of drying out to do I purchased a 6" and a 4" inspection port. The main reason I made this post is because the mast hole is cracked on the inside and there are a few areas I will have to patch up on the bottom of the boat. Do you guys have any tips on repairing this since I cant access the back side of the damage?
