<br/><br/> The effects of hull roughness on ship maneuvering characteristics are investigated. The hydrodynamic derivatives in the equations of motion for surface vessel maneuvering are modified to incorporate roughness of the hull and rudder. Vessel lifetime roughness profiles are postulated based on construction, coatings, operation and maintenance for a vessel life of 25 years. These are then applied to the turning maneuver for representations of several naval surface vessels types including an aircraft carrier, destroyer, amphibious support ship and two auxiliaries. The implication for naval missions are discussed.
