When I got my Freedom Hawk 12, due to scuppers not being that great and my launching of the yak by standing with one foot in it, both hands on the stand up bar, and one foot on the launch pad, I ended up with a lot of water floating around inside the yak.
I bought Freedom Hawk's Elite Guide seat, which is apparently made by Jackson. Typical Freedom Hawk, there was no package to mount the seat. My sons, one is a construction management engineer and the other is an avid biker and a wine cellar master came to their Dad's help. They installed a couple of pad eye hooks and attached the seat with the greatest invention for man since Velcro, Plastic Cable ties. It worked great.
Then, I bought the FH Pathfinder and got a small discount by saying I didn't need the uncomfortable and wet standard seat. We cut the cable ties on the FH 12, and put the Elite Guide Seat in my new Pathfinder and used the eye hooks on the Pathfinder.
The seat is very comfortable and the back angle can be adjusted, but not the seat height and angle. One could Rube Goldberg to adjust the seat height and angle if desired.
The seat is very sturdy and is going on its fourth year. It is built so any water on it will drip down to the yak floor.http://store.freedomhawkkayaks.com/
