Just do it - the best decision I've made for both my PA14 and my Solo Skiff. I can haul either over soft sand for long distances with minimal exertion. I like having the wheels with me at all times which sure came in handy down in Baja this last trip when I had to portage over 1/4 mile of sand bar that exposed itself at low tide...
is it advantageous in high surf conditions like 2-3' ? what happens if you roll in open water or surf? I've never rolled an PA on open water, but don't tell me it can't happen. just curious? I would imagine, if you rupture hull that it would be advantageous?
