A few more comments from me, on this subject.
Every boat is a compromise. Bigger is usually a better ride and deeper V, for going fast, is always the way to go. Of course with the deeper V, we will need much larger power sources to push it. I've owned bigger and I've owned deeper V's, so with the C-Dory, we don't plan on going really fast, we want a comfortable boat, that doesn't break the bank and one that we don't need to mortgage our home to pay for the fuel that we consume.
Now back to the subject of this thread, there is not a substantial difference between the ride of the 25 and the 26. I have ridden on and driven both for hundreds of hours and the difference is that I can plane the 26 in the mid teens and not have the pounding/slap that I had in the 25, for the same wave state.
One thing that I do want to add, is that I use the wipers more on the 26, then on the 25, as the very minor difference to the chin, simply causes a bit more spray. What I find even more interesting, is that on my 22, I really had the spray and this is why I never found a need to change from manual to electric motor wipers on the 22.
If the 26 had not fallen in my lap, I would currently own a 25, because there are more of them. The real selling point for me on the 26, is that it has a deep well deck aft, like my 22 and no squishy hatches with mold under them and in them to constantly mess with. I also am fond of two fuel tanks above deck, like on the 22.
