We call it a "Jac" because it’s better than an ordinary Jon boat; it’s an all-welded boat that will provide the stability for hunting and shallow water work and stand up to rugged use.
The narrow series fits into tight duck blinds, and into the bed of your pickup. The extra width and depth of the Wide Series Jacs provides additional stability and buoyancy. This helps keep you dry and allows for larger payloads and larger motors.
