Airplanes, and semi trailers are riveted.
They aren't designed to float.
Not only that, but pressurized aircraft leak air constantly. They have pressurization system that constantly maintains pressure but inside cabin air is always leaking out.
On a boat the highest pressure on the hull is below waterline. It's not air trying to leak in.
I've been in dozens of riveted boats and noticed very few problems. What I do note on talking to craigs list sellers is that a fair number of riveted Lunds have been repaired.
Also noted that a fair number of welded Crestliners have had issues. Mostly with the transom.
It aint a perfect world, and I'm thinkin g harder on the G3 that I passed on. It's in good condition, but reasonably priced. And I know I can break anything...
