Exactly, if it was leaking back then it should have been replaced then. If not Hobie's solution was the reinforcement kit. Many dealers miss this because they don't do a lot of volume.
At last years JBay tourney my buddy Jimmy and I fished on Thursday. He had an Adventure he got from me the year they came out. When we landed he was messing with the kayak and appeared to be emptying water. I asked if he had a leak. He did. I then how much and he said only a few gallons . I asked if that was the original hull he had gotten from me. It was. I checked it and the front drive area was cracked. He recently had a a fish finder installed and other upgrades and the dealer missed it. I check every Hobie I run across that's a few years old. Most owners were unaware of the reinforcement kit and without it many fail. Hobie stands behind them but its easier to prevent then replace.
