What year did C-Dory start injecting foam, and how can I see

Hi, I'm new to the C-Dory neighborhood and am looking for my first C-Dory! I'm hoping to find the right 22' Cruiser and I have been doing some research. I read that there's a big difference in the safety and interior quietness between the earlier models that didn't have the foam injected in the hull, and the later ones that did. Is this really the case, and was it a specific year cutoff that they switched the design? If it was mid-year, is there a way I can tell the difference?

Thanks for any info, I want to make an informed decision when buying my first Dory! :-)

Take care,
Beartrack
 
I do not remember any flotation foam, either injected or preformed foam in my 2003 22. My 1989 16 has foam under each gunnel and at the bow.

The following comes from:

http://www.uscgboating.org/safety/boatbuilder/flotation/intro.htm

Monohull boats under 20 feet in length and rated for more than two horsepower must comply with the more sophisticated flotation system called Level Flotation. The Level Flotation system requires that the swamped boat, loaded with certain weights representing weight capacity, part of persons capacity and some equipment, must float in an approximately level position and not heel past a certain angle, even when part of the passengers’ weight is on one side of the passenger carrying area.

Our 2002 22 cruiser has foam under the V berth and associated liner.
I tried to remove the inspect port, and found it quite difficult because
the foam attached itself to the inspection port. No big deal, but if you
can't remove the port, that may be why.

I'm going to guess that if there is no access under the V berth cushions,
the area is probably filled. But that is just a guess!

How about the older boats? I don't have an inspection port but would like to use some space under the V-Berths. Is there foam in a 1994 22 Cruiser? Inquiring minds want to know.... I do too!
 
My 1992 C D cruiser 22' had foam under the foreward v bunk (no tanks).
My CD 25--2003 has a water tank and foam under all of the V bunk area.
I assumed that most of the boats had foam, unless they were removed, or in the Tom Cat 255 series. I would not base my decision to buy a boat based on if there was foam there or not. My CD 25 still is plenty noisy powering into 2 to 3 foot seas....
 
My 2000 has no inspection port. Not sure if it has foam or air or water?...

What location did the factory choose to install inspection ports on the CD22?
 
Evidently these boats are standard as a snowflake, but my inspection port is in the floorboard in the v-berth. My watertank is under the rear seat (opposite the stove).
 
The port is under the porta-potti. I wonder if its function is not so much
an inspection port but rather a way to inject the foam and easily close up
the hole? In my case, the foam stuck to the port, and I had to remove the
screws and pry it off. I mostly wanted to make sure there were no water
intrusions issues like some C-Dory owners have reported (water moving from
the anchor locker into the foam.) We were good to go.

I'm betting you're right. I filled what little space was there with salt, it's a trick I learned from the WWII guys -- if water does get in and you don't catch it, the salt will pickle the water and pickle the wood instead of rot it right away.

My 2007 CD25 has its water tank in the stern between the batteries almost touching the transom.

I wear glasses, which might explain things, but I haven't seen an inspection port in the v-berth. I've never removed the cushions.
 
Sarge,

I wouldn't try drinking the water out of that tank on my CD25. Its the holding tank! :shock:
My water tank is under the V=Berth and I just cut a hole to put in a round hatch with a clear cover that will let me see the water level without opening the hatch.

Ron, I assume that your water tank is under the V berth on the port side.
Good idea to put in the clear inspection plate.

I have a 35 gallon water bladder tank for longer trips where water might be a problem, which will fit on the floor between the two "V" berths--or could be put in other places

Not sure when the holding tank was moved--but all of the 2003 and 2004 CD 25's have the holding tank aft--where the water tank is currently.

The newer boats use the sea land holding tank (about 10 gallons) built into the base of the head.
 
Ron - could you post a pic of this inspection hatch & its location? I would really like to be able to see the water level in the tank!

My boat is a 2006 model and the water tank is dead centre of the v-berth, The fill is on the port and my holding tank is in the stern.

Happy to post the picture. I'm just in the midst of spraying so Delta T Mascoat insulating coating on so the boat is kinda torn apart. I also made the v-beth door wider. I'll post some pictures on the weekend when camera (and hopefully my wife) comes back from its week in Palm Springs.

How big is the holding tank on the pre-2007 CD25s?

Bob Austin is right, my holding tank is 9.5 gallons and is part of the head, which is probably why my boat dips to starboard when at rest. With the kids, it is always being used!
 
I would guess that the holding tank is close to 25 gallons--from the outside dimensions--I can measure exactly--but some origional owners may still have the brochure or spec sheet .
 
I'm finding that 9.5 gallons fills quickly when kids are around! Not that I'd want to carry around 25 gallons of black water, but it's 2 1/2 times more volume...more time away from a dump station.
 
Mine is forward under the V-berth like others have said. I put a porthole above to get to the hose fittings (fill/vent) and also a large hole in the footwell area to fit a full hatch for viewing water level. I discovered my tank was put in at a slight tilt (for stability I was told...), looks to be 20 gals, but only holds 16.5 due to the tilt.

Tried to load photos, site still having problems. But here is a link to an earlier discussion and a link to my photos in the detail photos section.
