You are in a sailing vessel at night. Astern of you, you see a vessel's lights as shown in picture 1, on the same course as yours. With no other information, you know: That there will be a risk of collision only if the range decreases and the compass bearing does not change.
When underway in a power-driven vessel, which vessel must you give way to? A vessel not under command.
You are in charge of a 12-metre vessel in the Gulf of Eilat at night, under sail only. You are sailing slowly about half a mile offshore, showing sidelights and a sternlight as the law requires. A large tanker appears on your starboard side, and you are right ahead of her bow.

Your vessel is power-driven and has a working radar. At night the radar shows a vessel 20° on your starboard bow at a range of 3 miles. By eye, her navigation lights are hard to make out.
