With regard to comfort, we traveled an estimated 36 miles during the week, and there were no issues. The padded seat was comfortable and the adjustable foot rests allowed me to change positions as needed. The big question in my mind was going to be portaging. For frame of reference, I am 44 y.o. and in decent shape. Our trip included three meaningful portgages. 75 rods, 180 rods, and 200 rods. there were a number of short 25 to 35 rod portages. The prototypical kayak portage is over one shoulder. I was able to portage fine, but I have a few comments:
i) I used a short piece of swim noodle on the gunwale to pad my shoulder;
ii) the lower gunwale cut across my hip quite uncomfortably- at first I used my rain gear as a pad to protect my hip, but that was cumbersome. After some trial and error, I figured out that if I placed my rain pants over my belt that the lower gunwale would rest perfectly on my belt resulting in a good weight distribution between my hips and shoulder. However, this only worked on my right side and not left (not sure why). Of course, each person's physical build, and therefore comfort, will be different so it will require trial and error. Once I got it figured out, it was no problem.
