I recently got a “too good to resist” deal on a 2000 Eddyline Falcon and got it out for the first time today. The stock seat pan took some getting used to. There’s a very pronounced hump in the center, making it feel almost like a bicycle seat. At first it felt very funny, but after a while I stopped noticing it. It does give a very locked in feel when you also push the legs into the thigh braces.
I’m wondering if this seat is something unique to my older kayak, or is it a style used elsewhere? I don’t know if I would choose it over a more conventional seat, but it is surprising how well it works.
