Go to about 1:00 at this
I suppose it's pretty hard to reconstruct what went wrong at this point, and it wasn't on my boat, so I'll admit that either of those things COULD have happened. Our hunch at the time, however, is that it had more to do with being crushed/loaded "asymmetrically" while it was under water, by other poorly-rigged objects that shifted. (Again, being toward the end of the trip, people were starting to let their guard down and get lazy.) I think it probably distorted just enough to create a leak at the main seal.
It's interesting in that video that they used a ramp to drive the car onto the top of the box, where of course
you'd expect it to support the load. I'm more interested in what would happen as the wheel drives onto the box without
For what it's worth, we had one of the top-opening boxes - a #1430, perhaps? In any case there's probably a good lesson here regarding loading and rigging diligence. For me, it would be pretty hard to trust one again though. Like most things, I'm sure it works pretty well for 99% of the things you'd ask of it, but it's that other 1% that might (and did) happen that matter.
On a related note, I agree with the previous posters who said that accidents are more likely to happen away from the boat. So after the leaky pelican box incident, I started putting the major kit in a small backpack, and then put the backpack in the ammo can. That way, it wouldn't be necessary to lug the ammo can out on a trail somewhere.
