The following factors
shall
be taken into account when executing the plan or deciding on any departure there
from the plan:
x
The reliability and condition of the vessel's navigational equipment;
x
Estimated times of arrival at critical points for tide heights and flow;
x
Meteorological conditions, (particularly in areas known to be affected by frequent periods of low
visibility) as well as weather routeing information;
x
Daytime versus night-time passing of danger points, and any effect this may have on position fixing
accuracy; and
x
Traffic conditions, especially at navigational focal points.

The following information
shall
be entered in the Passage Plan and marked on the appropriate chart, where
it enhances safe navigation:
x
Parallel indexing (not from floating objects unless they have been first checked for position);
x
Chart changes;
x
Methods and frequency of position fixing;
x
Prominent navigation and radar marks;
x
No go areas;
x
Zone indicated by navigation warnings;
x
Landfall targets and lights;
x
Clearing lines and bearings;
x
Transits, heading marks and leading lines;
x
Significant tides or current;
x
Safe speed and necessary speed alterations;
x
Changes in machinery status;
x
Minimum UKC;
x
Positions where the echo sounder
shall
be activated;
x
Crossing and high density traffic areas;
x
Safe distance off;
x
Anchor clearance;
x
Contingency plans;
x
Abort positions;
x
VTS and reporting points.
Charted passage planning information
should
not
obscure printed details, nor
should
the information on
charts be obliterated by the use of highlight or felt-tip pen, ink, etc.
Zone indicated in navigation warnings
shall
be temporary marked on maps present onboard, with clear
reference to the warning reference, date it was received, and if available, date
should
be cancelled.
No go areas
should
be temporarily marked, showing areas where the attention of the navigator needs to be
drawn to a danger such as shallow water or a wreck close to the course line.
Extensive use of no-go areas
should
be discouraged. No-go areas vary with change of draft and tide and
shall
therefore also vary with the time of passage. They
shall
not therefore be permanently marked.
