Under Rule 19 — Conduct of Vessels in Restricted Visibility, what should a navigator remember?
A
The key principle is: if the other vessel is on your starboard side, you give way.
B
Rule 19 applies when vessels are not visually in sight of one another.
C
Stand-on vessel initially maintains course and speed.
D
Rule 18 is about responsibilities between vessel classes, not a magic answer that replaces the rest of COLREG.
