Through extensive use of scale models in ship testing tanks the scientists were able to document the phenomenon called interaction. They discovered that when two vessels approached, the sudden pressure effects which build up are sometimes greater than can be counteracted by rudder and engine. Interaction effects are most pronounced in shallow water and at speed.

The film is an aid to practising ship handlers. It shows case studies and some of the test results, thereby raising awareness of the subject and offers advice on how to accommodate the sometimes unavoidable effects.
