1979 Old Town Laker 16'

Came upon one recently that is available, lady that has it in her
backyard doesn't know anything about it except that it floats in her
pool. Does anyone know if this boat is single or double hulled
fiberglass? In any case, is this canoe worth restoring? It needs new
decks/gunwales/seats and possibly some fiberglass work. Can fiberglass
this old still retain it's structural integrity even through sunbaked
summers outside?

Thanks in advance!
