Question 10

A PDV is apporaching on your starboard side, action?

Answer 10

Take a series of compass bearings to ascertain if a risk of collision exists.
If a ROC exists ,this is a crossing situation so as per R15 i will avoid crossing ahead of the other vessel and take early and substantial action as per R16.
Ensure my starboard side is clear, Sounds 1 short blast, alter course to starboard passing astern of the other vessel, continue to monitor until well past and clear.

Answer 16

Sound signal: 1L + 2S / Lights 2 all round lights in a vertical line the upper and lower being red and middle white / Shape: Three shapes in a vertical line the upper and lower being black balls and middle diamond / Length can be determine by the masthead lights.

Question 17

Answer 17

Lights: 3 all round red lights in a vertical line / Shape: Black cylinder / Yes length can be determined by the masthead lights.

Question 18

When identifying trawling / fishing vessels, can length be determined by their lights configurations?

Answer 18
