Yep, I got that from you original post. But you also asked if it will be too narrow for an 18' cat. The answer is yes.
So here is the deal I have a 66" on my 15wd and 16' JPW that I just sold. It looks weird on my 15wd but it is a play boat and that is about the right size. the 16' Jacks just looks stupid but before I sold it I used it on smaller rivers so I dealt with it.
Your cat is a BIG cat and besides looking weird, you will be surprised at how much more stable it is and how much more gear can go in a 72" frame. That said, if your getting a good enough deal on the 66" just get it and use it. If you decide its too narrow you will easily be able to sell it and go the the 72" later. IMO for what its worth.
