Boat Operation & Navigation Rules
Q1: The phrase "red right returning" in the U.S. Aids to Navigation system means that
when returning from sea:
A. Red buoys should be kept on the vessel's left (port) side
B. Red buoys should be kept on the vessel's right (starboard) side [CORRECT]
C. Red buoys indicate the deepest water channel
D. Red buoys mark areas where vessel speed is restricted
Correct Answer: B
Rationale: "Red right returning" is one of the first phrases we teach in iLearnToBoat
because it keeps you in safe water. When you are heading back toward shore or
upstream, red markers stay on your right side.
Q2: Before launching your 18-foot bowrider for a day on the lake, you run through your
pre-departure checklist. Which of the following is the MOST critical item to verify before
backing the trailer down the ramp?
A. That the fishing rods are secured in the rod holders
B. That the drain plug is properly installed [CORRECT]
C. That the cooler is stocked with ice
D. That the stereo system is functioning
Correct Answer: B
,Rationale: Forgetting the drain plug is one of the most common and costly mistakes
boaters make. If that plug is not in, your boat will start taking on water as soon as it hits
the lake, and you could be looking at a sunken vessel before you even leave the ramp.
Q3: A displacement hull is best described as a hull design that:
A. Rides on top of the water at high speeds using lift generated by the hull shape
B. Pushes through the water rather than rising on top of it, providing stability but slower
speeds [CORRECT]
C. Is designed exclusively for personal watercraft and small tenders
D. Requires a jet drive rather than a propeller for propulsion
Correct Answer: B
Rationale: Displacement hulls, like those on trawlers and sailboats, move by pushing
water aside rather than planing on top of it. That makes them slower but generally more
stable and fuel-efficient for cruising.
Q4: You are loading your 20-foot center console for a fishing trip with four adult friends.
The capacity plate states "Maximum Persons: 6" and "Maximum Weight: 1,200 lbs." Your
combined passenger weight is 850 lbs, and you have 400 lbs of gear and ice. What is
the correct action?
A. Proceed as planned since you have fewer than 6 people on board
B. Reduce gear or passengers so total load does not exceed 1,200 lbs [CORRECT]
C. Move all gear to the bow to improve balance
D. The capacity plate only applies in rough water, so you are fine on a calm day
Correct Answer: B
Rationale: The capacity plate gives you a maximum weight limit for a reason, and that
includes people plus gear. Going over 1,200 lbs makes the boat unstable and increases
your risk of swamping, even on flat water.
Q5: While preparing to dock, a passenger falls overboard near the stern. The engine is
still in gear at idle speed. Your FIRST action should be to:
A. Throw a life ring toward the person immediately
B. Shift the engine to neutral and shut it down [CORRECT]
C. Put the engine in reverse to back away from the person
D. Jump into the water to assist the passenger
, Correct Answer: B
Rationale: A spinning propeller is one of the deadliest hazards on a boat. Before you do
anything else, you get that engine into neutral and shut it down so the prop stops
turning. Then you can focus on getting the person back on board safely.
Q6: You have just finished fueling your boat at the marina. Before starting the engine,
you should:
A. Open all hatches and run the blower for at least 4 minutes [CORRECT]
B. Start the engine immediately to clear any fumes
C. Wipe down the deck with a dry cloth
D. Check the oil level and add fuel stabilizer
Correct Answer: A
Rationale: Gasoline vapors are heavier than air and can pool in the bilge, creating an
explosive mixture. Always open the hatches, sniff for fumes, and run the bilge blower for
at least four minutes before you hit the starter.
Q7: In the U.S. Aids to Navigation system, a red lateral marker is typically shaped like a:
A. Cylinder (can)
B. Cone (nun) [CORRECT]
C. Sphere
D. Diamond
Correct Answer: B
Rationale: Red markers are cone-shaped, which we call nun buoys, and they carry even
numbers. Green markers are can-shaped with odd numbers. That shape difference
helps you identify them quickly, even if the color is hard to see at dawn or dusk.
Q8: You are cruising upstream on a river and see a green can-shaped buoy marked with
the number "7." You should pass this buoy:
A. With the buoy on your right (starboard) side
B. With the buoy on your left (port) side [CORRECT]
C. Between the buoy and the nearest red marker
D. Only during daylight hours
