My home town is in that part of Northern AR where Supreme and Shawnee boats are made. Supreme is cadillac of fiberglass jon boats in that area. Most the guides on the White River run a Supreme boat. Supreme is basically a modern version of the Shawnee. They have the walk through live well and several dry storage boxes. It is a little wider than the Shawnee which gives you a lot more room in the boat. Supreme has a completely flat bottom vs the Shawnee that has the 2 support boards that run from the front to back on the floor of the boat.
Shanee has been using basically the same mold for there boats for years and has not ever updated there body style. Shawnee is a good boat that is a lot less expensive than the Supreme. I think a new Supreme boat and trailer runs around $5,000-7,000.
My Shawnee works fine but it would be nice to have more room and the built in dry storage boxes.
