North Fork Outdoors inflatable SUP's are high quality and have some unique features like a raised seat.
Pros
Raised seat/storage, 4 or 6 inch depth, 36 inch width can handle the big boys, affordable price, excellent for sight fishing, motor mount available
Cons
6 inch model is a little heavy.
Usage
Mostly I fly fish from it on stillwaters, but it can certainly handle rivers too.
