Bert ( among others, and I’ll apologise for the omissions now) has been doing some interesting things with higher density foam inlays and/or laminations, cos if the foam underlying the glass isn’t dense enough, you’ll have to go pretty heavy on the glassing to make up for it. But this involves tooling, labor, investment and skills that most manufacturers are unwilling to get into. Hell, they are selling boards now, and if the easily stomped boards are selling just fine and there’s few if any alternatives, well, they figure screw the customer.
Me, I reccommend to anybody with a new board that they get themselves stomp pads, real quick. Soaks up some of the heel impact, spreads it out a little. But that’s kinda like a wheelchair approach: yeah, it takes care of some of the problem but it’d be better if there wasn’t a problem in the first place. Heavier glass plus stiffer foam at the surface of the shaped blank, that’d take care of the problem. Carbon and kevlar and such - ok, they have considerable tensile strength, but they deflect just fine unless you have a very thick, heavy lamination approximating that of polyester/fiberglass. No real gain for the higher expense and difficulty. Epoxy is somewhat stiffer, but it too costs more.
This actually has some bearing on the ‘resistance to change’ topic too - as you mentioned, the deck dents lead to delams which in turn lead to expensive repairs, breaks or most likely having to buy a new board. One notorious example, the H__ies and the St____rts, are famous around here for deck delams and lousy glassing in general. But they are selling and they even have lots of repeat business. And the measure of success is whether or not they keep selling their badly made boards, not whether or not the boards fall apart. Planned obsolescence, y’know?
Why? Well, the general run of surfers ain’t exactly sophisticated about materials and manufacturing processes and such. They are here on Swaylocks, yeah, but this is a small subset of surfers as a whole. The general run of the surf biz…well, don’t get me going on that.
Ah well… life is a carnival… just gotta stay clear of the sideshow.
