Manoeuvring large ships at close quarters and on shallow water is one of the most difficult aspects of shiphandling because of the complex hydraulic interactions depending on the ships' speeds, on the water depth and on lateral restrictions like in canals. Training is conducted both on meeting and on overtaking ships in shallow waters. This video shows how overtaking in a canal can easily fail.

It remains a sad fact that accidents and near misses continue to occur during pilot transfers with frightening regularity. Most of these fortunately do not result in injury, and a surprisingly high number of them are not even recognised for what they are.
Surveys into pilot ladder safety consistently reveal that unacceptably high numbers of pilot transfer arrangements are not compliant with the regulations.
