For the record-I own a Phoenix-
I went and looked at a Caymas yesterday at a Dealership in Florida. Beautiful Boat. It is a Boat that would make anyone proud to own. The Hull on both Boats seem to be very close to the same, (I did not ride in the Caymas), I was told by the Dealer that the Caymas is a Heavier boat--(Good or bad, I don't know?) The storage compartments seemed shallower in the Caymas than the Phoenix, up on the bow. The rear compartments on the Caymas are Huge!! I did not see any locks on the latches for the Rod holders on the Caymas. I like the Latches on the Phoenix better than the Caymas, as you can just open and shut by a pull. The Caymas has adjustable Seats going back or forward. I did like the Console on the Caymas better than the Phoenix, as it is completely accessible from underneath. The trailer that the Caymas was on is a C channel, (U channel for those in the steel industry), which I do like better, than the tube type. The seats to me seemed to be the same as far as comfort goes. The rear access for pumps and such is a little better on the Caymas than the Phoenix. The Battery shutoff switches location is definitely better on the Caymas. The Deck 's, Front and Back size seemed to be about the same. I was told by the Dealer that there is no better riding boat out there, (I don't know how much of a better ride you can have over a Phoenix, more than likely about the same). Neither boat has a Pad on the bottom. Fish ability, to me seems the same. Price wise for us that don't fish in the FWL, or Tournaments, is about the same.
I would say if you are looking at either one to buy, have fun in deciding and good luck!! This is just my opinion, not bashing any Boat, as they are both great boats!!
