has anyone seen cracking ( 2 actually) in the hull liner on the stbd side of the main bulkhead where it meets the overhead. approx 10" outboard of the compression post and again 16" from that . liner is cracked on the fore and aft sides of the bulkhead. no noticeable sagging on deck at the step. wood under compression post is also fine. no noticeable movement of deck or any of the mast step componets. Does the liner even carry a load there? what are your thoughts on this. im having a pre purchase survey on sat. original owner from 1976 says it came from factory like this. boat is otherwise in excellent condition. thanks for your reply.
