Note that rubber, also used for rub rails, has all the properties

But the stuff may make good rub rails.

The composite plastic/wood for boat building is a bad idea for so many
reasons, that one should not consider it:
1) It glues poorly.
2) It is not stiff--saggy is a nice way of putting it.
3) It is very heavy.
4) It is often more expensive than wood.
4) It does not hold fasteners well.
5) It is ugly.
6) It has very low dimensional stability.
TimberTech touts if with these reasons:
Low Maintenance
Resists Heating & Fading
Safety
Durability
And none of these particularly apply to the product use in boatbuilding.
Painted wood is low maintenance as, say, a gunwhale. Heating and fading
pertain to walking on and leaving out in the sun (which I hope you won't
do with your wooden boat), it adds no safety (it reduces the overall
flotation of the boat, in fact). It's more durable, but how many Bolger
boats have failed due to rotting of gunwhale material?
In sum: Do not use it. It provides virtually no advantage, on price, on
looks, on service, on durability, on safety, on workability. There is no
reason to use it, except as an experiment to try it out. As long as you
maintain access to the fasteners, it's not so bad to try, because you'll
be able to replace it during the first season with a proper piece of
douglas fir.

I have data convincingly disconfirming the Duhem-Quine hypothesis.
