This means that a vessel could be 2 miles away or less. Therefore, I will reduce my speed to a minimum to maintain my course or I will take all way off and navigate with extreme caution.

Question 9

There is a target on your port bow and a target on your starboard quarter, what are your actions?

Answer 9

As per rule 19d(i) so far as possible I should avoid altering my course to port for a vessel fwd of my beam however and as per 19d(ii) so far as possible I should avoid altering my course towards a vessel abeam or abaft by beam. Therefore, I would slow down or because the rule states “so far as possible” I could still alter course in this situation and I would choose to do so where there is the most sea room.
