Patrick,
The cooler (as I mentioned is a little smaller but still very useful) is the step up on the PIV it is just back in between the consoles where the Puma has it out in front of the consoles. You loose the daybox the Puma has due to this also, while it is handy and I use it for my bouy’s, extra hooks, scents, extra pliers, nails and extra line I could easily put in in another bin.
The deck space is nearly identical but the PIV is just slightly wider and shorter (albeit not much in either direction) than the Puma.
No length issues with the PIV, my buddy places 7’6″ rods in his with absolutely no problems. That is one advantage to the two boats you have narrowed down too, the rod boxes are longer and provide a ton of room to put rods in the lockers without bending the fire out of your rod tips.
