I built a failed experimental dory using Pink foam - 1" and 2", sheathed
with epoxy/glass. More than 15 years later, it's still deteriorating in
the yard - the epoxy/foam bond was never a problem. Very
expensive/time-consuming for trying out a lousy design. But it was light,
strong, and unsinkable!

If it was light, strong and unsinkable, why was it a "failed" experiment?


It was expensive and time-consuming. And oh yes, the hull shape was very
unstable, inefficient, slow, and one or two other problems.

But upside down under a tree, it makes a nice warm winter home for
porcupines.
