Radar Watchkeeping
The IMO has given the following guidelines for “Officers in
Charge of
a Navigational Watch”, with regard to the proper use of radar.
1 The officer of the watch should use radar
when appropriate and whenever restricted visibility is encountered or expected
and at all times in congested waters having due regard to its limitations.
2 Whenever radar is in use, the officer of the
watch should select an appropriate range scale, observe the display carefully and
plot effectively.
3 The officer of the watch should ensure that
range scales employed are changed at sufficiently frequent intervals so that
echoes are detected as early as possible and that small or poor echoes do not
escape attention.
4 The officer of the watch should ensure that
plotting or systematic analysis is commenced in ample time, remembering that
sufficient time can be made available by reducing speed if necessary.
5 In clear weather, whenever possible, the
officer of the watch should carry out radar practise.
