When can a vessel enter a separation zone
A vessel other than a CROSSING vessel or a vessel JOINING or LEAVING a lane shall not normally enter a separation zone or cross a separation line except:
(i) in cases of emergency to avoid immediate danger;
(ii) to engage in fishing within a separation zone.
To avoid a Close Quarter situation what may be the most effective action if there is sufficient sea room
If there is sufficient sea room alteration of course alone may be enough provided another CQ situation isn’t caused.

C - CHARACTERISTICS, efficiency and limitations of the radar equipment.
R - any constraints imposed by the radar RANGE scale in use.

I - The possibility that small vessels ICE and other floating objects may not be detected by radar at an adequate range.
N - The NUMBER location and movement of vessels detected by radar.
E - The more EXACT ASSESSMENT of the visibility that may be possible when radar is used to determine the range of vessels or other objects in the vicinity.
