Rule 9 requires vessels to keep as far to the starboard side of the channel as is safe and practicable.

Question 4

A vessel engaged in fishing with nets has restricted maneuverability. How many white lights does it show at night in addition to its sidelights?

Accepted Answer

One white light above a red light

Answer

A vessel engaged in fishing shows a green light over a white light (or red over white if gear extends more than 150 m) and sidelights when underway.

Question 5

What signal must a power-driven vessel sound when overtaking another vessel in a narrow channel to pass on the vessel's starboard side?

Accepted Answer

One prolonged blast

Answer

In the US Inland Rules, one short blast signals intent to pass on the other vessel's port side; one prolonged blast is used in other contexts — however, overtaking signals in a narrow channel use one short blast for starboard-side passing.
