I’m not sure how tensile strength relates to deflection. I won’t pretend to be a physicist or anything but a decent fabricator. I just assumed that for the same weight stronger is better.
I need to put up a pic or two so you guys will better know what I’m up against. I don’t feel like this is a difficult problem to tackle but I’d rather not have to do it again later.
looked it up..
tensil is described as "pull apart" strength. like a snapping steel cable.
for a 15' skiff your transom will be what? 7-8 square feet?
three sections of 1" square tube bonded/welded together should provide sufficint clamping surface. you might go with a thicker wall for that part and fill it with spay foam ...
or you could just use a aluminum plate like they do on inflatables and RIBs..
I wonder what material inflable transoms are made from?
you could pick up a trashed inflatable and cut the transom out...
