Vessels with high block coefficients feature underwater hulls that closely resemble rectangular cuboids, maximizing internal volumetric capacity for bulk cargo and vehicles. However, this full-bodied geometry creates substantial hydrodynamic resistance, making the vessel highly sensitive to minor rudder inputs and prone to continuous course deviations.

As a result, high block coefficient ships require active steering corrections to hold a steady heading, making them far easier to maneuver in restricted ports and locks but much harder to keep on a straight line across open waters.
