I do not have a Kona, but I do own an Oasis. I do have a buddy who owns a Kona. He uses it to fish on the Colorado River (Blythe area) and rides wave with others.
Have you thought about an Outfitter or Oasis. I throughly enjoy my Oasis. I use it solo or with someone and on all types of water (fresh, salt, protected, and open). I primarily use it as a pedaling sailor, but am ready to start fishing with her.
May I suggest you take all out for a test ride before purchasing. Enjoy and have fun.
