I noticed today that I'm developing a crack in the circular top rail in the back corner of my boat. I have attached a rough drawing to illustrate the location. Actually I have one on both sides, but the one on the left has grown much farther than the one on the right. This is an obvious concern for me because I'm sure that it has grown in a short amount of time. It is probably due to the new rod rack that I bolted onto the two triangular flanges and just the vibrations from trailering. I put the rod rack on about a month ago and I have only taken it out about 4 or 5 times since then. So it is growing kind of quickly. My question is if anyone has had this happen to them and how they fixed it or if anyone knows any product that will stop the crack from growing? I cannot weld and from what I've read in other posts, its hard to find someone who can weld alluminum anyway. Besides the crack started at the edge of the weld where it is the weakest, so if I got it welded again it would probably just start a new crack just in front of the new weld. Right now I'm thinking that I'm going to have to get rid of the boat if there is no way to fix it.... what do you guys think, do I have any options?
