So, with a decent swell running last Friday I stuck my camera on the mount with the extension bar to see how it would fare. I began with the camera in the upright position, which as expected fared well, and gave a nice image of the sea & paddler in perspective.
I then mounted it offset on a 45 degree angle to capture Rob paddling alongside, and in some turbulent water, including a few small breakers across the deck, again everything held solid.
Finally, we set up up at deck level, out off the edge of the gunwale, pointed back up & across, where it was often being dragged by the moving water in concert with my hull speed. No problems, with a short amount of time to make sure the cup is fixed and holds, everything is well designed & the results are excellent.
The conclusion, this is another great piece of kit from Kayalu that stands up to the rigours of sea paddling.
The Kayalu Toughbar 8" extension arms are available from the online store for $39.95.
