There was a Sterling here in so cal too, in Buena Park if I remember right. Typical 70's builder, v-bottom jets, outboards and cruisers, but they did make a cool outboard tunnel kinda like the old Carlson tunnel. Not a splash of the Carlson, but along the same lines.
This is not it but it is the same hull. The thing has a long wide nose that droops downward more off shore style, also the thing is not very deep, shallow runner, v bottom. Jacuzzi has some sort of kit, ride plate, diverter, and pump setback. I'll post pictures soon but this appears to be the same boat.
