Tooling Up

[Thunderhead19]

Cathedral hulls (Boston whaler) are...what's a polite way to say it...a pain in the ass to do in aluminum. They are doable, but obviously it requires several times the linear feet of weld that it would take to build a similar v-bottom boat. I don't have any cutting patterns that I could sell you. I might know someone who can help you though, give me a couple of days.

Pull-up method is when you assemble the hull plates as a shell first (pulling the plate up from the floor) rather than building the internal framing first (then pulling the plate down over the framing.)
