but I wanted to hear some verification. The core of the boat is not wood in most places no? Meaning, except say in the hull, for reinforcement (say keel area) the hull is cored with something else right?

I drilled through the bulkhead to mount a (much needed) depth meter, and found NO wood core, so therefore (in my pea brain), I have nothing to worry about with rot...

What I am getting at is if I were to pull the wretched windows and replace them with windows I fabricate myself (1/4" acrylic perhaps) ala Capri 22 (26, 250, and several others), using butyl tape say, I want to make sure I don't need to stand on my head worrying about rotting core, even given the fact that the windows will be outside and the exposed area inside.

a follow up to my own question (since that technique seems to be happening a lot by the professional question askers in the press during this presidential year for our gold old USA) different topic. How do you keep your boat dry summer and winter from what appears to be mostly condensation. Is this a "Breathing" issue for my boat (I have canvas overtop most of my cabintop most of the summer, and tarps over the winter)?

Right now I am using a 40watt bulb left on to keep the cabin warmer than the outside, in hopes to dry it out some. Remains to be seen if it's helping (been sitting 4 days now).

Hull is cormat sandwich with layers of woven and strand glass with polyester resign. Plywood is sandwiched at the keel to hull joint.

There is a outer hull that is attached to a deck layer and is secured on 12" centers with butal tape and stainless screws that are under the rub rail. Sitting inside of this is a interior pan. The pan is cut at the windows and the deck layer.

There will be a void between the two. It's not solid.

There should be construction photos on this site I got from Catalina yachts about the construction.

Hope this helps

I couldn't remember where I saw it, but it does verify what I am seeing.

As for the buildup of moisture in the cabin, you can get some of the throw away pellets that soak up most water an I also used a small heater design to keep the interior of the boat warmer when its too cold outside.
The best method is to circulate the outside air into the boat and get enough air moving that the temp is constant and will not allow water to form on the ceiling. A couple of solar fans that you can set one to input and one to output should move enough air to keep it dry.

Is kind of what I was thinking just wasn't sure (solar fans that is). Didn't have this problem on my 22, but I think the hatchway was loose enough, to provide more air flow.

Moisture issues in the boat is caused by warm humid air in the cabin that then cools during nightimes and the water in the air then condensates out of the air.

You can eliminate the moisture issue either by installing a dessicant container that absorbs the moisture in the air or by installing a solar fan.

Dessicant containers generally come 3 ways: Throw-away containers which means continually buying new ones. Electric ones that you plug into the AC outlet or removable ones that you bring home and plug into an outlet overnight and then reinstall it on the boat. I have the removable one whereby it has a window where you can see the dessicant and when it turns from blue to pink, then it is time to bring it home and plug it in. When plugged in, the small unit heats the dessicant and drys it out. Then I re-install it. On my boat, I have clothes hanger wood dowel above the head and the dessicant container came with a hook that allows it to hang off that dowel. The unit I have is called "Eva-Dry". I have used the same container for years with changeouts 1-3 weeks depending on the weather. It comes in various capacities and was originally bought from a Boater's World store that used to be in my area. West Marine does not carry it. There is a mfr's web address to check it out:

http://www.eva-dry.com/products/?utm_source=MSN& utm_medium=CPC& utm_term=EvaDRYBrand& utm_campaign=SearchEVADRYBranded& menuPhone= 855 %20292.6460

I also have a solar fan - A Nicro unit. The Eva-Dry is hanging in the head area and the solar fan is in the main cabin top. I know -----Having both these units is sort of counter-productive. Anyway, the solar fan works well. It exhausts air out the cabin top with the air coming in the hatch board vent. The way it works is that by replacing the inside warmer humid air continually with cooler air, the warmer air does not have time to cool and release the excess humidity thru condensation.

I never take my cushions home as I sail all year-round but there are definitely longer periods of non-use in the winter months. The cushions and the boat do not have any signs or smells associated with mildew ....well the boat does not have any smells or deterioration -period. When I do install my cover over the boat when significant snow is predicted, I will either take the battery out of the solar fan or turn it off (the new Nicros have an ON-OFF switch). But then I still have the dessicant container onboard and the period that the cover is on is generally from 1-30 days but I can still get onboard to get to the dessicant container if I want to bring it home to dry out the dessicant.

Well, in about 3 weeks I will be moving my boat indoors... We're moving and my hope is the boat/trailer will fit in our new metal building (crossing fingers it'll fit).

At that point I may remove most things from the boat because I have a bunch of work I want to do. Meanwhile the boat sits on my front lawn (in my old house)with the canvas cover on it and hopefully drying after lots of accumulated moisture as it's gotten quite cold (picture this with a canvas cover over just the cabin).

Ok, I am 3 weeks into this now, using a 40 watt lightbulb in the cabin, and it's dry as a bone. Very happy that I don't have a mildew smell, or wet cushions to deal with. I am about 2 days away from moving my boat into the garage for the winter, for her long awaited refit.

Here we are sliding the boat back into her winter cocoon... Very tight fit

No seriously VERY TIGHT!

Lots of room inside though, not a lot of head clearance though ;)

Well it'll be a couple weeks until I can focus on the boat again... In the meantime I have to decide on a color I want to paint the hull, and acquire all the sandpaper and VC17m I need, along with barrier coat. I'll be taking her down to gelcoat, fairing, and working my way back... I'll try to document the process.

hull looks like it still has some pretty good gloss to it? Why paint? instead polish or compound and polish.

if you are looking for a change, others have been able to gel coat with good results.

Ape-X that is the best shine I could get out of the 20+ year old Awlgrip (and I didn't wax it again since July, so that shine is 5 months old). You know looking through my pictures, I don't have a good one of what she looks like up close, but the paint is so old that is cracked/peeled in places. Also a prior owner painted a name on the stern, and silly me removed it with 100 grit sandpaper (thinking it was white gelcoat) ONLY to find out the boat was white awlgrip painted over baby blue hull. So there are some nice shiny light blue hull spots shining through now!

At first I thought someone spilled/splashed paint on the hull and painted it to cover the spill then I started to sand/polish, and got right down to light blue (UGH)...

While I suspect I could sand/buff off the paint, and get a nice layer of gelcoat, I don't know how I feel about having a baby blue boat.

I like dark blue, and royal blue... but I'd like something more of a bada$$ look. I know she's old and all, but I just ordered new rags, and am gonna have her ready below the water line, so I'd like something that says sleek and fast, perhaps red, or better black (I know cliche', but nobody has either color in our club or on our lake, so it seemed doable). I think eventually I'll be doing the windows, and kiwigrip the deck. My hope is to make her as nice above decks as she is now below (since the prior owner recovered all the cushions, and lacquered every square inch of wood with 7 coats.

i've seen some really nice looking silver hulls. Perhaps a metallic paint?
