Paul,
I was wondering if you could post some pictures of your captain's cabin. Specifcally, what gauges were used in his room, where did they mount the fan, and did he have a sink and a mirror?
On Batfish, we have a heading gauge, but another one has been removed and plated over. There is no mirror/cabinet nor sink. I think that this is because the access to the battery hatch is right below where a sink should have been. I haven't even seen any signs of previous plumbing or that a sink was ever mounted there, but I wouldn't surprised if he at least had his own cabinet with a mirror.
Finally, I can tell that other items have been removed from the bulkhead near the doorway. I'm guessing that a 9" fan was probably mounted somewhere on the angled bulkhead so that it would blow down onto the bunk.
Granted, I also know that each boat is unique and even furthmore depending on which boat yard it came from.
Thanks.
