The displacement tonnage can be reduced while the cabin space can be increased, for a better cost efficiency. Large cargo vessels, can be designed allow railroad cars to roll directly into the hulls, and unload in the same manner. Any Hydro-Lance ship is designed specific to the partner or customer's market, and mission. Cargo Turnaround can now be measured in hours, not days. . The hull behaves much like an arrow.
More energy is required to turn the moving arrow than to keep it straight.
The speed shortens the wave frequency, gaining greater stability and less stress. The results are amazing. Turning the Hydro-Lance vessel is accomplished from the bow, as different from more conventional ships with stern rudders. The slight angle change of the nose section allows the hull to track in a turning radius of two arc degrees per second at the rated cruising speed, and even faster for emergency situations. At harbor speeds, trusters are provided in the rails for tractor turns and docking. .
