I wonder how the new 22 cruisers float now (filled with water)? My 2008 apparently has foam under the V berth and under the cockpit floor.

Would they now be unsinkable?

Any thoughts fellow brats?

C-Dory...
Any thoughts to testing the new ones like Arima did?
(if you could call them "unsinkable" or "full floatation" it may be an extra sales feature.)

Stefan-

We've discussed this before, and, based on the evidence, the C-Dory 22 Cruisers fully flooded (as in "pooped on") with intact bow tanks (air chambers) float upside down, stern down (motor weight), with just the forefoot underside of the bow upward, but pretty much awash.

Don't think the foam under the floor would make a lot of difference, maybe raise the rear of the hull a little.

Unsinkable? Yes, as long as the air flotation chamber is intact. Not sure if the foam in there alone would keep it afloat, but guess probably not with the motor weight, and all else, considered.

But unsinkable is a long way from being "self-rescuable", of course, and even getting a fully capsized boat towed to safety wold be a major feat, IMO.

Thank goodness they very rarely go under and turtle!

Joe. :teeth :thup
 
The bow area has been turned into storage, and the hatches are not water / air tight. The 22 (and larger) is not required to float level if swamped. While it might be a sales feature, take a look at the 19 and see how much cockpit space one gives up to get the foam flotation for that boat into it.
 
"Unsinkable" was a registered trade of Boston Whaler, or, at least they tried to get it to be.

There are CG regulations mandating level flotation, but I think they only apply to boats up to 20 feet in length or so.

And, level flotation is quite a bit different than being able to only see the bow eye when swamped.

Old Whalers also tend to get their foam waterlogged, despite it being closed-cell, and I expect that C-Dory is the same. An extra 1000 pounds of hull weight above factory spec doesn't help flotation (or, performance).
 
This is a topic near and dear to my brain as I rebuild and extend my Classic 22. I've only scratched the surface of the topic of flotation foam, the cubic footage needed and - most importantly - where to place it. I'd very much like my boat to stay upright even if the sole is 32-inches lower than normal. Me inside the hull trying to stay warm; sharks outside trying to remember the tastiest parts...

I've got other issues at the forefront now, but so far it appears as though judicious placement of closed-cell foam wouldn't take up more room than it's worth. I've considered glassing foam into the hull sides but this'll all take more evaluation than I've given it so far. I really do like being on the dry side of the water...
