Sorry about that. I think a lot faster than I type
What I meant was that adding weight and "trailer" frames to your Dave Scadden rowing module isn't a good idea, and that the Scadden module probably isn't up to the task of class III with bigger tubes at all.
I don't mean to be toooo
offensive, but I think of the Scadden pontoons as oversized pool toys, but the way one end is connected (raft style) it supports your rowing module and reduces frame twist. Sure, they will take on class III, but it's not really what they're made for. If you add 30% or more to your tube size, even if you use extra frame modules, the rowing module is still your weak point. Cargo modules, or passenger modules, won't stablize your tubes the way the round end of the Scadden boat does. Maybe
if your extra modules had lowers (drop rails) they
would stabalize your tubes and take stress off the light weight frame from the Scadden...or maybe they'd transfer flex and twist into the little rowing module in the middle and break welds.
Or maybe I'm FOS
