homemade single seat pontoon boats?

[jason41987]

foam is less buoyant than air.. so just having air in it would give you better flotation.. but the foam would continue to float even if the skin is punctured... however, the skin on mine will be very hard to puncture so im not too worried about it...

so i still think building a form to make a hollow rigid shell with would be the way i would go... but im still not sure i want to fish off a personal size pontoon boat which is the real decision im facing right now.
