I have a 1985 ALUMAWELD 1440. At the front of the boat (where it rides against the trailer rubber bumper wheel at winch) there was a crack that I had welded. Well it has happened again, only worse this time. The crack is about 9" long going right down the center of the middle rib and through the previous horizontal weld. I'm surprised at how super thin the aluminum is. Does anyone have any suggestions or pics on how to fix this or how to prevent this? I'm considering trying to beef up that section and possibly putting a new bow eye at this area also.
