We all know we need nav lights for when the sun goes down but it’s important to understand what we are looking at when we see the lights on other boats – they all tell a story. It’s also necessary to know the rules surrounding lights. Here’s a short quiz to test your knowledge. Good luck!
- Navigation lights are designed to:
- Actually indicate the relative heading of a given vesselThat is true!
- Indicate the distance from your given locationNav lights are not designed to figure out distances, but if they are really big you’re probably too close!
- Provide on deck illumination in addition to nav related informationNo, that’s what a flashlight is for…
- Provide forward illumination not unlike headlights on a carIncorrect – boats don’t have headlights…
- The arc of light that the stern light casts is 135-degrees, the same as:
- The “overtaking zone”You got it!
- The turning radius of most sailboatsThat’s funny – you must have accidentally hit this button
- The “Herreshoff zone”We made that up…
- The “leading zone”We invented that term for this quiz…try again.
- Sailboats under 60-feet:
- Must have two stern lights and one multicolored bow light when sailing in limited visibility or at nightNo, one stern light is plenty.
- Must, by law, have spare emergency nav lights onboardNo, that’s not right but not a terrible idea.
- May carry the sidelights and stern light in a single lantern on a mastheadYes!
- May not carry the sidelights and stern light in a single lantern on a mastheadNot right, lighten up!
- A vessel at anchor is required to:
- Display a blue light at as high an altitude as possibleBlue lights are pretty, but you are incorrect.
- Display an all around white light where it can best be seenYou are right and we are proud!
- Display a red light from the spreadersThat sounds like an exotic place to be but it’s not a correct answer.
- At least carry Coast Guard approved neon glow sticks and display them from a place where they can best be seenThe CG approves a lot of things but not green neon glow sticks…
- “Sidelights” are:
- White (port) and blue (starboard)Sorry, that be wrong!
- Blue (port) and green (starboard)Nope, maybe you haven’t been night sailing yet?
- Red (port) and green (starboard)Of course!
- Both redNo – hint, it’s two different colors.
- In a crossing situation:
- The vessel that can see the other vessel’s green light is the give way vessel. Incorrect – be careful out there!
- The vessel that can see the other vessel’s blue light is the give way vesselNo – blue light?
- The vessel that can see the other vessel’s red light is the give way vesselYes!
- Lights have nothing to do with who gives wayActually they do!
- A vessel under sail:
- Should have their steaming light onIt’s easy to confuse but that is not correct.
- Should not have their steaming light onYou are right!
- Should have the blue “sailing beacon” litUh no, what made you think there something called a blue sailing beacon?
- Should have their yellow “sailing beacon” litWe’ve never heard of a yellow sailing beacon…try again!
