about your engineering logic having seen many of your posts. You need to be careful, because you do talk a good enough game that some people might believe you as gospel and do some damage....watch out for unintended consequences. For instance, in this case you viewed the area where the two skins converging over the edge of the foam to be something like "half of an I-beam". A few problems there. I-beams aren't designed to be loaded in tension on the flanges...the flanges are there to stabilize the web (half I-beams are shitty things to mess with anyway, but that's a different matter). More importantly, it's structurally NOT half an I-beam, but, in 2-D a wishbone with the anticipated load pulling the two legs of the wishbone apart. That's not good, because there is a stress multiplier where the two skins (legs of the wishbone) meet. Assuming the foam to be of minimal strength in tension, the load goes to the skins (leg of wishbone), the stress seen at the crotch of the wishbone is 2,3,4 or more times what simple calculations would show, and voile, you pull the skin laminations apart...oops. As an engineer, my first move would be to call Wenonah and make an inquiry as to where to put the attachments...because, I don't know for sure where the best place to put the attachments is, but they most likely do. There's at least an hour into this whole forum line, some of it is okay and some of it is wrong. Wenonah might actually have a 1 minute answer to the question. In engineering, you don't engineer what you don't need to engineer. "I don't know" is a really good phrase for any engineering student to learn and use...keeps people from getting hurt.
