I think the real question has to do with size and weight of the Kayak. I carry mine in my pickup with a bed extender in my trailer hitch receiver and a Rack Back. I also mothership on to my boat… Life is good.
Very good points, salmontim. I don't worry about keeping up as long as I keep site of others in my party. A few miles offshore doesn't bother me since I can still see the horizon line at 5 miles or so. I have no idea how far we peddled since we trolled one particular area for about 4 hours, but loved riding the waves so far! I'm sure there will come a day one when a wave will nail me good, but that just comes with the territory as far as I'm concerned.
I too use my truck bed and bed extender for day trips. For longer road trips, I use racks on top of my Tacoma, then invert the PA12 to rest on it's gunwales and tie it down "canoe style". I'm still perfecting my top rack loading technique as I'm 61 and do it by myself.
Since you take yours to your "mothership", do you tow it behind, or are 'ya lucky enough to bring it aboard? I've got an offshore 26' CC and was wondering how well my PA12 might tow so I can bring my baby along when we're on the water.
