This is the hatch in the aft head with the ceiling down. That is wet wood right there. But no rot. Haven't had time to investigate it properly but it might be teak. I saw that wet area and thought "Ah hell, here we go." Stabbed it with my knife and it is solid. It is leaking and has to be fixed and it might be leaking into a cored balsa area so I really need to investigate but at least this area is OK. After Swiftsure, I take the hatch off and see what I see.
