After exactly one season of fishing and kayaking under my belt, I think fishing from a yak is a blast.
I have a Scupper Pro by Ocean, and am getting an XFactor by Malibu, just to give you a couple more models to look at.
The Scupper is a wet ride, the XFactor is not.
One of the paddle sports companies hosted a demo days last summer in SLC, you may want to investigate that.
I’m a big guy, 6’4", 240lbs, and I can sit in my yak all day comfortably, I do use a high back seat for back support.
Wind is a problem, but possible, it just makes it more work to paddle, not like a canoe, where wind is a killer.
The lower the yak is in the water, the less the wind can grab it, i intentionally went out in foul conditions last year with a fully loaded yak, just as a test, and in 20mph sustained winds and 2’ chop I still paddled from Hideout to Carter Creek (5 miles?), it just made it harder to track a straight line, and the ride was wetter than usual.
Boat control while fishing was difficult, but this year I will have a ‘sea anchor’ (drogue) and an anchor trolley system to help deal with boat control.
I don’t paddle in winter, only because I don’t have the right gear, with a drysuit you could still paddle in cold weather.
Yak fishing is a blast, check it out, you won’t be sorry.
P.S. For some ideas, check out plasticnavy.com, these guys fish saltwater, and you won’t believe the amount of rigging possible on some yaks, fish finders, nav lights, up to a dozen rod holders, bait tanks/live wells, bait cutting boards, fish lockers, outriggers, trolling motors, you name it, and someone has it on their fishing yak.
