... The effects of hull roughness on loss of speed at constant power are investigated. Vessel lifetime roughness profiles are postulated based on construction, coatings and maintenance. These are utilized to determine loss of speed and change in running attitude for planing boats. The formulations...

... 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...

... The effects on Required Freight Rate (RFR) of hull roughness causing loss of speed at constant power are investigated. Vessel lifetime roughness profiles are postulated based on construction, coatings, operation and maintenance. These are utilized to determine the loss of speed. The results...
