Bett's method of construction for aluminum.
Actually that is not aluminum or aluminium for that matter. Every part of the boat you see in that photo is .125" Titanium as well as the hull plating. Keelson may be 1/4"  (instead of 3/8") as Jim didn't like the big difference between the thickness of the two plates for welding.  Lots of pitfalls welding with Ti!

Betts sent out welded test panels to a testing lab and they broke their machine twice in pull tests. We are going to need a bigger test machine. One of the test panels sent to the client was subjected to first his big Dual Cab Dually pickup running over it on concrete. Then he had the big high rise forklift at the marina run over it. Still no issues. Then he had the 100 Ton Travelift run over it and he finally saw some bending at the welds but no cracking. All the welding is being done in an inert gas shield.

That has got to a pricey build!
