insulation

We are insulating the sides of the v berth with foam and wood strips. We haven't decided yet what to do with the ceiling. Any suggestions?

Tinker Toy,
Here is one solution...
This is ceiling tile material, with thin wood trim, to improve appearance.

I have closed cell foam that I will attach to the side walls. I have cut and planed them to .20" so they are flexible enough to bend to the curves of the hull. I will place vertical pieces every 2 feet, to these I will screw 1 1/2 wide pieces parallel to the vberth. The wood is cherry and has one coat of boiled linseed oil brushed on.

Will post photos while in progress.

I used flex Form Marine Carpet, was really easy to install and worked great!

We virtually had no moisture accumulation in the v-birth other than a little underneath the memory foam mattresses; was going to put some of that Marine bedding mess underneath the mattresses but never got around to it.
The Wallace recommended an inside & outside air return. My idea with putting the inside air return all the way forward what's to draw air from the cabin up into the V birth, and it worked well enough.
The Flex Form was easy to install because it's stretched in both directions you just need to use the highest number spray adhesive you can find, spray booth Services wait for about 30 seconds and then just put it in place and press. I purchased through an upholstery shop locally not sure where he acquired it.
If I were able to convince the wife I would have placed it on the roof of the cabin I think it would quiet things down quite a bit when underway and of course add an insulating quality
By far the Delt T spray insulation was the bomb, on the 22 I sprayed it in the v-birth and the cabin, you could practically talk with a whisper when underway Plus moisture was eliminated totally amazing stuff. I applied a good latex semi-gloss over the whole thing. But man that was a lot of work masking everything off and spraying on multiple codes and it wasn't cheap.

Jay,

Thanks for the tips on the insulation and heating. I am going to have a better look at my plans and begin sourcing materials. I also plan to insulate the cabin roof, as we get some dripping here as well. You have done some very nice modifications on your boat and thank you for posting your photos of your projects. It makes it easier for us to envision how we might do ours.

Have just been using the cheap back packing pads for our 25 forward cabin. Not got to the ceiling yet--maybe some time during this lock down...I probably will put some Sunbrella or more resistant material over the pads eventually.

For our Cal 46, we put a PVC expanded foam headliner material glued onto 1/8" thick deerskins for the pannel. We screwed teak battens over the joints so the panels were easy to take down. Behind the panels, we glued on "fish blanket" which was available in almost every fishery supply or hardware store in AK. Some areas I finished out with the lightweight covering material used on airplane inside hulls--it was surplus at the McDonald Douglas store...Don't know if Boeing has anything like that as a surplus?

Boeing used to have a large surplus store in Kent, WA (or maybe Auburn). It was a neat place to go. You could get all kinds of interesting stuff. They used to get new deliveries from the various Boeing facilities on Mondays. On Tuesday morning before they opened there'd be a long line of people waiting to get in to get first dibs on the "new" stuff.

When I worked at BCA, you could hardly throw anything away. It all had to be sent to Surplus so they could decide what to resell and what to pitch out.

Boeing closed the Surplus store over 10 years ago. Probably because there were a lot of people that worked there and it was cost cutting time ('bout the time they moved HQ to Chicago).

Once again

I recommend Bedrug

it's 3/4 inch foam that's made to withstand the elements
of being in the back of your truck

It's sold in six foot widths and you have to buy at least ten linear feet

The raw material is not corrugated like what would go in your truck

Used it on the floor in my 22

Way nice for only $2/sf

Bedrug is like I said "way nice" for only $2 per square foot

No need for the plastic slats holding the fuel cells in place

This material is rigid and 3/4 inch thick and

Great on your feet and knees

For ceiling it also comes in 1/4 inch thickness

Fish guts and blood wash right off

May very well line the cabin with it next

Made a paper pattern of the floor and
then cut the Bedrug with large scissors to fit

Finally making some progress. Used double sided carpet tape and covered the walls with closed cell foam. Then installed vertical boards to which the horizontal boards are attached. Will be a total of 12 boards 1 1/2" wide spaced 1/2 inch apart. Planned them to .20 inches thick so they would have some bend to them. One coat of boiled linseed oil on all wood.

Wood is cherry.
