A rare sight. Four of the Hawaii Pilots Association’s pilot boats were gathered together in Honolulu Harbor, which provided a great photo op.
Research on hydrodynamic interaction indicates that if the speed of the ship near a bank is too high, the rudder may be less able to cope with the forces induced and control will be lost. The Nautical Institute highlights this in its latest Mars Report, in which an LPG carrier hit a barge being towed by a tugboat as a result of hydrodynamic forces.
