We are looking at a Tanzer 8.5 in great shape except for one issue. On the
deck directly above the bulkhead, there is two identical cracks [that have
been gelcoated over]. They are about one foot long and run from the outer
edge of the deck toward the center of the boat.

We don't know how to evaluate what these cracks are trying to tell us about
the design or condition of this Tanzer. Any thoughts?
