Easiest may be to add 2 new metal pad eye's (Hobie # 71220001) to mount the seat to, and just epoxy or plastic weld the crack and hole.
I like the idea of new metal pad eye, but will the small metal screws be enough to hold such a tension from backrest. If you compare it to the original which has pretty deep reach I'm little skeptical. By now I know that I have to weld it or use some heat reacting glue to close the seal.

BTW How can I get the same color plastic as is my kayak? Does Hobie send scraps to their customers?
