I have the balance point of my canoe marked with a piece of tape on each side, so I know exactly where to place the yoke clamps in a hurry. The clamps on the commercial yoke are tightened with large knurled knobs. They do not have to be super tight to hold firm and I have not noticed any damage on my Rapidfire wood gunwales. The adjustement point does not really change when I store my paddle centered underneath. With my Rapidfire I have a hand line going from bow to stern clipped together in the middle, long enough to comfortably grip it at hip level with one hand. It controls the tilt of bow/stern as I walk. The bolt holes for my custom bent tubing yoke are in one fixed location in my Hornbeck gunwales. I don't worry about yoke balance adjustment with my Hornbeck because the bottom support rod makess the whole contraption fixed and rigid.I have one very similar (if not the same) as Glenn's. Mine has aluminum clamps so I glued on some ccf so as to not damage wood gunwales.
Can you describe how your strap yoke mounts? I was trying to invent something like your picture for my solo peregrine canoeI made a strap yokes.
I considered purchasing a solo canoe and wanted a carry yoke that was lightweight, quick to deploy, easy to stow and would not be lost or misplaced. I often make and modify equipment so this became a DIY project.Can you describe how your strap yoke mounts? I was trying to invent something like your picture for my solo peregrine canoe
