Glad to hear you are considering getting into kayak fishing.
It is great sport and you will enjoy it very much.
There are plenty of good kayaks out there but I only feel comfortable recommending what I use. That being said...
I'm sure everyone will chime in on their faves.
However, few can attest to thousands of hours on the water with their selected kayaks.
I make my living using kayaks. That being said, my fleet of Ocean Kayak Scrambler XT Angler Editions gets put to the test on a daily basis.
Unless you physically exceed the specifications of the Scrambler, there is no better kayak for the money, period.
