Encapsulated in poly resin, not epoxy, right? I suggest you do some
research on the water permeability of various resins and you'll discover
that your stringers will eventually get wet.

And wood in general is strong. Properly installed wood substructure
(encapsolated stringers etc) will last a good long time. The problem of
course is if water does get under the encapsolation.

My stringers are pressure treated fur that is encapsolated. Time will
tell how it will last in the long run. Much will depend on how I care
for the boat. But I do not fear it will fail any time soon. One might
guess that a poorly made fibreglass stringer system may develope cracks
over time. I am sure one properly built will last a lifetime. As will a
well built substructure made of wood.
