I should have qualified my Fathom LV seat comfort statement to note that I removed the backband and hinge, replacing it with the Eddyline “floating” backband (which was specified in my order but they screwed up). Didn’t like that one either so I replaced it with a smaller backband from CLC, which sits much lower. The new owners of the company are working on redesign of that backband setup. Also glued minicell foam to the bare plastic around the seat because of the pressure it caused on my tailbone.
They use Sea-Dog foot braces (now called Sea-Lect). Nice brace because it’s so easily adjusted while in the boat. A good paddling shoe comes in handy on rocky shorelines.
