depth of hollow behind side paneling in salon

[JDubya]

Hello everyone! I recently bought a used 2021 C-30S and am about 4 good non-work-days and 3 underways into getting settled onboard. This is my first recreational boat, although I do have a couple of decades (plus) of active-duty Navy time that help me not be 100% clueless. I've been poking through these forums and am glad to find so many helpful and knowledgeable folks willing to share ideas and help troubleshooting, I've already managed to learn a few things and get some good ideas.

That said, now that I'm getting settled onto the boat, I'm finding that I have some (probably oddball) questions.

So my question today: how much room is there to attach something to the teak bulkhead paneling in the galley/salon? I'd love to put a brass clock (family heirloom) in that space between the windows, but am not sure how long of a square-head screw it would be safe to go into that paneling with. It looks to me like there's a bit of a hollow behind that panel, but I'm not sure there's any way to measure it apart from eyeballing it. My other thought is to use rivets, but I'd hate to drill rivet pilot holes into that paneling and then discover that there's not enough room behind the panel for rivets to work.

Any thoughts or experience with putting something on an interior bulkhead (or non-destructive ways to get an accurate measurement of how much room I've got behind that panel) would be greatly appreciated.

Have you considered bonding a “plaque” to wall with liquid nail and then mounting the clock to it. The plaque could highlight the clock. With out knowing what is behind the wall, you could hit a wire and then you would have a bad day. I would design the plaque for something else too, in case you ever want to take the clock down.

hey JDubya,

I don't have a photo handy, will try and take one this week but I mounted a set of brass weems and plath clock / comfortmeter (the 085 series) on the teak trim above the windshield center window in my C30-CB. They came with a plastic mount and 4 somewhat small screws, and I didn't have a depth issue with them. It's certainly not thick, but that's one option you could consider as far as placement.

The plaque is a great idea, I'll definitely consider that.

Although, after looking up the Weems & Plath products Dave mentions, I may have to leave the heirloom in the house and get that matched set from them at some point!
