I hear people say all the time that "they rivet things so they can flex and move". I've got news for them; if a rivet is allowing movement it is failing. Simple as that.
If you wish you can PM me your neighbors info along with the boat info and I'll make some phone calls. I've gotten to know a couple of the Legend reps from out east that would be all over that.

Actually it's because aluminum welds do not develop the full strength of the parent material. High strength aluminum is also tricky to weld properly. Rivets are also a lot easier to deal with when doing repairs on an aircraft. Aluminum welds do gain strength as they age (or are heat treated) but still not parent material strength.
