C-Dory Problems

[toyman]

I am considering a 25 cruiser in the future. I've been lurking & looking at the photos on the C-Brats and have a few questions about the integrity of the core on the C-Dory. How many experience water intrusion into the core thru unsealed, or improperly sealed attachments ? How common are cracked transoms on the 25's, are they more prevalent on twin engine installations - or large singles ?

I presently have a Whaler Outrage and I've had experience with water in the core – it isn't nice.

One thing you'll find with the end grain balsa core is that water won't migrate far from its entrance point if the core should be compromised, unlike the whaler which absorbs water though out the foam core.

For some reason there are two parallel threads. There is an exception of the water migration with end grain balsa--and that is if the boat is exposed to freeze/thaw cycles. In this case, the core will be damaged further, and may start delamination, which will allow more water spread. For example, the C Dory 25 had deck core damage over 6" from the place of water intrusion. The deck cracked and further damage occured--I have to assume that much of this was due to the freezing temps in New Jersey during the winter.
