Hard to tell from the pics - kind of fuzzy. Hobie plastic isn't weldable, so you're left with epoxy, and the only stuff I've heard about that will stick is G-Flex. However, I've also never hear of a Hobie Getaway hull failing at that point, despite having seen even worse cracks. I'm sure they will and have at some point; just haven't heard of it. Might check Hobie's Getaway forums for a real first-hand experience. For what it's worth, for the right price, I'd probably not let minor cracking at the beam sockets stop me. But, I'm not 100% confident either. You need more pics.
