Instructional film showing the organisation, necessary preparations and execution of various types of sea towing of Admiralty vessels by ocean-going and harbour tugs.
The role of the towing master is shown, illustrated by the the towing of a frigate by the tugs Typhoon and Dalmatian; problems, such as a broken towline, are encountered. The use of harbour tugs at the beginning and end of a sea tow is also discussed. Part of a towing master's job is to be ready for any emergency. This is illustrated by the twoing of the stricken frigate HMS Aurora; a towing line is transferred by helicopter and messenger cables are connected. The narrator notes that "no two jobs are the same".
