Growth in inland waterway barge transport has resulted in a steady increase in towboat propulsive power. Use of ducted propellers, multiple screw installations and tunnel sterns has enabled this power increase. This paper concerns the trends in comtemporary, high-powered towboat tunnel stern design. Tunnel stern designs from over 60 towboats are used to develop empirical formulas characterizing the stern tunnel design. Tunnel flow angles and are then introduced for use in avoiding vibration problems from poor tunnel flow conditions.
