I had my choice of the PA-12 or the 14 and I went with the 12 due to transportation issues.
I have both a pick-up and a trailer, but decided to go with the 12 due to the fact that it's much more convenient to carry a boat in the back of my Ford Sport-Trac
with a Harbor Freight
bed extender than try to located a parking spot for a truck/trailer combo. Many places that I launch on the Indian River do not have trailer specific parking, whereas a truck with bed extender can park anywhere.
Also, the prior statement about a trailer being easier to load/unload than a P/U is false. I have a kayak specific SportsRig
micro-trailer and it is easier and faster to use the bed extender....which is a benefit on tourney day, or saving on tolls while traveling on the Turnpike or finding that last public beach parking spot that is for cars only.
I may go with a PA-14 next year, but I find (so far) that the 12 serves my well and is more than stable enough for my 6' 225lbs "beer & brats physique" for standing and sight fishing.
