I think I figured this Ogeechee River boat out. Narrow stern for easy paddling. Also , with the boat facing downstream, the paddler would not be fighting the current as much to keep the boat in position. Central compartment for fish. Sliding front seat to allow the trot line handler/helper to balance the load. Wide front to carry a large payload. Large rake front and back to make getting out on a sloping bank easier. Unusual characteristics on work boats are almost always there for reason and have evolved over time.
