The OP should research why the skin on aluminum airplanes are riveted
rather than welded.
Hint: It has something to do with preventing the wings from snapping
off.

Next time I buy an aluminum boat with wings, I'll keep that in mind.




Cute, but not the point. Thin welded aluminum is subject to stress cracks
in anything that flexes. Rivets allow flex without losing structure. You
knew that.

The boats you provided a link to are designed from the get-go to be welded,
using large, continuous panels with welds that I am sure are reinforced and
placed in minimum stress areas.
