I have one in my cabin and absolutely love it! I regularly fish with another adult and it really doesn’t make much if any difference on space. If anything it’s better because I’m able stay a lot more organized and I don’t have to dig around to find what I need. You won’t regret getting one!
Best accessory you can buy in my opinion, I sold my cabin (it fit perfectly between the seats) and purchased a cottage and it fits perfectly with the single seat too.
