Just wanted to add my 2 cents here. I have a 2014 Outback and absolutely love it. I've peddled all the Hobie's, and for me the Outback gives me the speed/stability/storage/maneuverability that's a perfect combo. The PA is a great fishing platform but just a bit too big for many of my applications. I'm not the biggest guy at 5-7" 160lbs and often stand to sight cast, and move freely about the yak to access the front and rear hatch with no stability issues. The biggest improvement for me was the addition of the Browning turkey hunting chair mentioned above, it pretty much turns the Outback into a mini-PA. With the stock seat I can last 4-6 hours before needing to stretch my legs/back, with the chair added its a non-issue, I can be on the water 12-hours straight. The seat does raise the center of gravity, so for offshore or moving water situations I revert back to the stock seat. I can't upload any pics, but you can see the setup in the video below.
I can not get your link to open , that's was one of things I was looking at ,was to raise the seat also if I purchase the Outback .Do you have any pictures or details on what you did to get if to fit inside the Outback ? Did you actually attach the seat to the Outback ?
My Ride has an elevated seat and I can say that I can fish for hours and my legs or butt not going numb and it seems to give more ability to move around and get to your fishing equipment a lot easier . All though when it's a windy day ,you get blew around like a leaf on the water because you catch the wind setting up higher , I don't the ability to switch to a lower seat because I only have one position and I did not purchase a low seat . That's one of the things that really dislike about the kayak I have other than it does not have any pedals .
