That’s actually a decent price

But you don't need the fabric backed one for fiberglass those are designed for rafts and flexible hulls although it will work using almost any good adhesive from contact cement to epoxy. I used those on the interior of a plastic kayak with contact cement.
You can use something as simple as a folded over piece of webbing epoxied down although it's awkward getting a weight to hold it down in some locations.
Another time I used plastic d-rings with a split plastic straw over the straight part and a few strips of epoxied fiberglass attaching it to the hull. Just clean and roughen an area the size of the material holding the d-ring down.
1" Plastic d-rings are cheap, strong enough epoxied down with glass cloth or webbing. With a hard glass hull you don't need the large gluing surface that you need on a flexible inflatable or poly hull.
