pli-cor hulls, are they any good

[bobchaytor]

I am looking at a 68 tollycraft hull . It is constructed with pli-cor ,which is 1/8 fiberglass outer and innershell then sandwiched between them is a 1/2 layer of foam. Is this a good or bad design. Apperantly this is thier attemt to lighten there boats from using a plywood core.<br />The boat is a 23 footer which if I restore I am considering exstending the hull and mounting either 1 or 2 outboards probally 2x 100hp . any recomendations?
