CD-22 Cut-away, Mounting light over dinette

mikeporterinmd

Hi All,

Cutter Marine has a CD-22 sliced into a cross section. When I was there
in 2006, I took some photos. Finally got around to putting them in
my album. I'm not going to post a link in case I move stuff around -
but they are not hard to find.

Looks like there is maybe 1/8" of coring in the pilothouse roof over
the dinette? I'm going to mount a light over the dinette and am trying
to decide if I need to epoxy a board up first, or if short screws and
some caulk will work.

Thoughts?

Mike

If it were me I'd put a board up. Looking at the cutaway it doesn't appear that the raised section of the roof is cored like the 25. Is this correct. I was told they were cored.

There seems to be something in there. I made a blow up of photo 4 from the
original image. Maybe it's not balsa, but rather some other filler?

What is the year of the CD22 that is cut-away? It seems the lower roof section of our 2005 CD22 is cored and thicker than you've shown.

I don't know how old it is... probably dates from when the HINs started with
DOR... Smile

My CD is a high top, the core on the sides of the roof are 3/4" You can see this where the radar through holes are cut. The lights are just screwed into the glass. The top of the roof does not sound like it has any core in it when you knock on it.

Hey Mike...I can speak to that picture since I recognize it being on our boat. The original owner put them on. It is starboard with I am guessing 4200 or 5200.

One of the three eventually came loose so you may want to check with the gang which is the best adhesive.

Thanks, Mike, for posting pics of the cutaway. They are worth a thousand+ words! Wayne

Wouldn't the quick set 5 minute epoxy be a better option for mounting things like this? Seems you could hold the item in place for 5 minutes rather than wait a week for the 5200 to set even the fast set takes days.

On another note surely someone on the forum has mointed a roof top air on a recent 22 and can give some advice on the construction of the roof.

It's also quite simple to unscrew the handrails (outside and inside if you have them) to see how long the bolts are. This tells you the thickness of the cabin overhead.

The handrail bolts are very long. It is difficult to tell exactly how thick
the roof is. I'll probably avoid the risk and use epoxy.

Thanks,

Mike

This turned out to be very easy to do. The thickened epoxy took quite
some time to set up, and yet I used one of the faster hardeners.
(West System, mixed with the pumps).

Perhaps the thickener I used slowed the cure? Anyhow, the height
from the dinette to the light is right around the width of the seat back
cushions, so I jambed them up to hold the fixture. Worked well. We
had a very rough ride this past weekend, and the light stayed put.

A 22 watt flourescent fixture lights up the interior like (green!) daylight.

Thanks,

Mike
