Anomalous maneuvering behaviour has been encountered in large ships where the waterplane area is unmatched to the structure located thereon, as in the case of pure car carriers with large superstructures covering the bulk of the ship's length. Manoeuvrability problems affecting pure car carriers occur at low speed when pursuing restricted waterways, river channels, etc. and during port entry. Wind pressure may aggravate problems experienced. This paper discusses a number of associated manoeuvrability problems on the basis of a comparison of an unnamed 12,304-GT car carrier of non-Japanese ownership with a 43,000-GT tanker and 39,010-GT container ship. Recommendations are made on the appropriate rudder data needed to pursue confined waterways in consideration of wind pressure, currents, and other environmental factors. A number of ship design improvements to enhance course keeping are also instanced. Order from BSRA as No. 50,022.
