The Duke 12' & 14' Jon Boats
Dominance has a name—and it’s The Duke.
Built from 5052 marine-grade aluminum with seam-welded construction that shrugs off rough landings, sharp rocks, and hard use -- season after season.
With straighter sides, deeper keels, and serious backbone, the 12- and 14-foot Duke models are designed to handle more than just calm waters.
Whether you're tucked into a duck blind or chasing bass in backwater shallows, The Duke delivers strength you can trust and simplicity you can count on.
Born from over 80 years of aluminum boat-building expertise in Marathon, NY.
