I am very new to the boating world and I am looking at a 23? seacraft ( not sure of year yet). I went down to see the boat and noticed a few small cracks in the hull on the right side of the boat. They don?t appear to be holes or go all the way through the hull. How much do I need to worry about the cracks? How hard/ expensive would it be to repair? What necessary steps should I take to properly diagnose how bad the cracks are? Anything you got will help! Thank you in advance
