Back in the day when they first commisioned a 200 Osprey there was probably nothing different between the two, not even length. Just a way to make a bigger boat without having to create a new mold.
Now, if you're talking about the difference between a 70's 196 and a '02 200 - that's a different story. The CCP model had the tall gunnels, the Ospreys didn't - now the newer Ospreys have the tall gunnels. The CCPs had the deeper V hulls, the Ospreys had the 12 degree - now the newer Ospreys have the deeper Vs. So it seems they took the best of the CCP and merged it into the Osprey product line.
