What does one short blast on a horn mean in inland waters?
Answer: I intend to leave you on my starboard (right) side
In US inland rules, one short blast means the vessel is directing its course to starboard (right).
What does five or more short blasts on a horn indicate?
Answer: A danger or distress signal — the other vessel's intentions are unclear
Five or more short rapid blasts is the danger signal, used when the operator is in doubt about the intentions of another vessel.
What navigation lights must a vessel under 23 feet (7 meters) display while underway at night?
Answer: Combined red/green bow light and a white stern light, or an all-around white light
Vessels under 7 meters may display sidelights and a stern light or, if not practical, an all-around white light.
A vessel displaying a red light over a white light indicates what type of vessel?
Answer: A vessel engaged in fishing
A vessel engaged in fishing (other than trolling) displays red over white lights to indicate its limited maneuverability.
What does a flashing blue light on a vessel indicate?
Answer: The vessel is a law enforcement vessel
Flashing blue lights are used by law enforcement vessels to signal other boaters to stop or yield.
If you see both red and green lights plus a white light ahead at night, what is the other vessel doing?
Answer: The vessel is heading directly toward you
Seeing both sidelights (red and green) plus a white masthead light means the vessel is approaching head-on.
