I just purchased a 2013 PA14 yesterday, so I'm dealing with the differences in the 2012 PA14 seat that I'm used to and the Vantage seat. Since I don't have anything mounted on the rails of the 2012 PA14, I just coasted up to shallow water and swung my feet over to either side and let he PA drift in until I felt the bottom.
It's a different ball game with the Vantage seat arrangement. Getting in the 2012 PA from the ramp, I just walked it out deep enough to where the bow would not hit the ramp when sitting down and just back up to either side of the seat/rail and just sat in. Then swung my feet around and I was good. It seems you have to climb in/out more with the 2013 model due to the arms on the Vantage seat and the narrower seat.
I don't anticipate any issues after I get used to it after a few trips. The new boat got slimed this morning and the first bass landed is pictured below. So it was a great day!
