My 69' Seafari had the same drain config.
Strick, I was wondering what you used to seperate the top cap from the hull sides? I beleive you mentioned it was glassed to the hull, like mine is? I thought just running a cut-off wheel shallow along the inside corner might do it.
Also, I noticed you've left the boat on the trailer. Ive read several times that the hull might go floppy, or may not be square on the trailer after removing the cap, and its given me pause before I take that step. Any issues in that regard?
