[quote=tominpa]From your description there may be a couple things going on. It sounds like there was galvanic corrosion, which may have happened if stainless steel screws were driven through aluminum. The difference between a pop-rivet and an exploding head rivet is the pop rivet is held in place by a swelling in the end of the rivet barely larger than the hole, but an exploding head creates a large bloom of retention that acts like a washer up to 1/2" diameter. The exploding head rivet is in tension, pulling the pieces together, and if it pulls through, the hull is coming apart. My jib track is connected parallel to the trampoline track but is on a separate track and rivets. I know the track has a lot of pull, but to have it yanked out of the hull is way beyond my expectations. I have not modified the jib track rivets. I included an image of my jib track while on a beam reach at 20 Knots last summer. How does that rip loose?
