Oh - what Boatpoker said a thousand times over
We bought an S2, and were promised up and down the signs of water intrusion to the bulkheads had been dealt with.
It had not.
We drilled in to the bulkheads (post purchase
, clearly) and MUD and water came flowing out. The ply had completely
disintegrated. So we're just finishing up the starboard bulkhead replacement this week. Port was done first.
Not the end of the world, but's its delayed getting the boat wet by about a month. Really common issue, it seems. Google
Bulkhead replacement some time.
