Haven't yet, but been meaning to do a peddle/paddle/camp run with my Brompton and Alpacka Packraft - already short tour out the single front T-bag so rear rack is free for the boat. I also have/had a Travoy and a couple Feathercraft folding/inflatable yaks, but the Razorlite looks better suited for this purpose.

I've always liked the idea of self-sufficient travel by land OR sea, but dang hauling around ~40lbs/100L of boat/trailer for the land portions would sort of kill what I enjoy about multi-modal touring with the ultra-compact Brompton rig.
