This paper describes a new radar system which aims to give the Master of a vessel, on a television screen, the kind of information which could be obtained visually from a wheelhouse window in daylight in clear weather. The system was described by Mr. P.O. Prior at a meeting of the Institute held on 17 January and an account of the discussion will be given in the next number of the Journal. S. R. Parsons is Chief Engineer of Kelvin Hughes and Captain J. P. Stewart a Marine Consultant.

The early history of marine radar when the phrase ‘radar assisted collision’ was coined, the setting up of radar simulator schools to assist in teaching the interpretation of the radar picture, and more recently the increased number of collisions at sea, particularly in congested areas like the English Channel and the approaches to major harbours, all call into question the adequacy of the presentation of radar data on conventional relative and true-motion radar sets.
