Strip planking the foam is a possible way to build in foam/glass composite. I've helped build a moth that way, but only the sides, the bottom was heat formed sheets.

We found that strip planking such a small boat with 6mm foam was a nightmare! When glassing, the seams between the planks would crack under the pressure of a brushed or squeegee. A lot more frames and stiffeners were needed in the mould. The fairness of the final glassed hull wasn't good, you could see the edge of each plank poking out. It required a bit of careful filling and sanding.
