Scenario 2 Course change examples
1.
Course alteration to pass ahead of the Interception zone
[Not recommended]
— As the target
vessel is moving faster than your vessel you will pass astern of the target.
2. Course alteration to pass ahead of the first Interception zone
[Not recommended]
— Although
this course alteration is sufficient to avoid a potential bow-to-bow collision, it has created a
second Interception zone where the target may now run you down from behind.
3.
Course alteration to pass between the 2 Interception zones
[Not recommended]
— Although this
may seem like the quickest option,
proceed with caution
, as the gap between the 2 Interception
zones can close quickly, especially when your vessel slows down.
4.
Course alteration to clear astern of the target vessel and its Interception zone. This would be the
preferred manoeuvre as it correctly alters your vessel’s course so that it is clear of the target’s
Interception zone, and passes safely astern of the target. This manoeuvre also clearly indicates
to the target vessel your change of course.
