SP fishing is super fun and the added height above the water can be helpful. I fished from an SUP in the shallow water of the sounds on the Outer Banks off NC. I kayak fished a bunch too but the SUP was handy for pulling across mud flats, grass thickets, and for getting out of to wade fish. An SUP would work well enough out here. One thing I will say is that with nothing really under the water line and a persons big profile up in the air the wind moves a SUP much faster than a kayak.
The Jackson looks much better set up to fish but look at these too.
