A friend of mine recent bought a Nova craft prospector 16ft in tough stuff. They took the boat and tipped it to see how it would float and noticed that water had gotten into the flotation tanks, likely around the plug in the vent. This happens all of my canoes now leak a little around the plug, it surprised me that it happened in a new canoe. More surprising was there is apparently cardboard, that is now wet, in the flotation chamber.

Drying will be a problem given the size of the vent.

My question is about the cardboard - has anyone pulled apart a NC canoe and is there really cardboard. None of my composite canoes have anything (other than air) in the chambers.

They could have used cardboard as a substrate to start laying up the chambers.
A lot of the time they will have popcorn (or like) foam that's usually wrapped up in a plastic stuffed in the air chamber.

This method provide some assurance that if water does get in, it's not waterlogged yet.

Pull the end caps, drill several small holes on top of the chamber as close as possible to the stem.
Flip your boat and leave it upside down to drip dry.
You may have to play Egyptian embalmer by pulling any stuff out of the hole to improve drainage.

Others I've drilled a large 5" hole on the vertical side of the chamber and reached right in to take any damaged product.
Once it's empty, install an access panel so it can be used as storage.
WARNING.... this will compromise the air chamber because it won't be watertight when forced underwater.

If he bought it recently, returning it could be an option.

I'm not sure I get the idea of a Tuff Stuff boat with flotation chambers. I believe you can get it without chambers as an option. Without the chambers and an extra $150 or so, he'd end up with useful flotation and the option to easily get rid of the stupid painter hooks they put on those boats.
