This past weekend the sammich maker and I were down in Padre Island and got to use our friends' dual seater Hobie. Had a great time - she was simply giddy, which is a rarity for her. She even stated how cool it would be to have a 2-seater kayak.
My question is about seating, specifically back support. The only "trouble" I had on our kayak trip was that, my abs wore out from having to sort of do a half-abdominal crunch because the back support was so inadequate. My arms never got tired, but my abs did.
Are there options for better back support with regards to seating?
