Mark, I have a Pelican Trailblazer sit-in kayak. You might ask why I have that to fish in. Well, as I said, my daughter gave it to me as a surprise gift. If she had asked...
Now that I am once more hooked on fishing I have thought of buying a fishing friendly boat. But, feelings. I also take into account that this is a very light boat, and the ones I would be interested in are not.
Fishing from a paddle board has to be challenging. I assume that you are a minimalist when it comes to gear. I applaud that approach.
When I left Virginia, the serious river kayak fishermen all had sit-in boats, and usually carried one rod, maybe two at the most. Some fished tubes exclusively. And they caught fish, and big small-mouth bass at that. The salt guys in Florida had somewhat more complex rigs, and sit-on boats. Now, I am mind boggled when I look at some of the outfits that guys go fishing in. I have counted as many as seven rods, plus fish finders, elaborate anchoring mechanisms; and of course the ubiquitous go-pro. I doubt that those guys I knew are actually catching more or bigger fish.
I am working to get my boat organized; but, I will keep it simple.
