How long do Adventure Island sails usually last?

I bought a 2009 AI when it was just a few years old. I used it for sailing & the hull alone for fishing until 6 years ago when I moved. I finally got caught up enough to start using it again & I noticed some cracks on the inside of the hull under the click-n-go where it can’t be welded. I’m told it can only be fixed as a paddle kayak. Before I try for another hull, what is the expected life of a sail? When not in use mine was always stored in its bag in the garage. Can I expect the sail to last many more years or should I look for a newer AI?

I also have a 2009. Mine also has issues, and after chasing down various leaks, I decided to put in a bilge pump.That took care of the leaks. My sail is still in pretty good shape.
If you are talking about cracks in the tubes holding the cam bolts, there is a fix on this forum using loctite adhesive.

Thanks Sailchef. The cracks are definitely under the click-n-go, both sides front and back. Hard to reach and to see while reaching. Not enough room to use the Hobie welder. I will check out the other post.
