OBS Boat Operation & Docking Skills Flashcards

What is the primary cause of most recreational boating capsizings in small boats?

Answer: Overloading or uneven weight distribution

Overloading and shifting weight unevenly raise the center of gravity and reduce freeboard, making capsizing far more likely.

When returning to a marina in rough water, what is the safest approach angle to waves?

Answer: Take waves at a 45-degree angle to the bow

A quartering approach at roughly 45 degrees reduces the impact of waves while maintaining control and avoiding broaching.

Which of the following best describes the 'five-second rule' used in boating?

Answer: Allow at least five seconds of travel time between you and any object for stopping distance

The five-second rule is a simple way to estimate safe following distance, since boats cannot stop nearly as quickly as cars.

What action should a boat operator take when they hear a prolonged blast from a large vessel in a channel?

Answer: Clear the channel immediately; the vessel is signaling its approach around a blind bend

A prolonged blast (4–6 seconds) signals a vessel's approach to a bend or area where visibility is restricted, warning other traffic to clear the way.

What is the correct response when your boat is the stand-on (privileged) vessel in a crossing situation?

Answer: Maintain course and speed, but be ready to maneuver if a collision becomes imminent

The stand-on vessel must maintain course and speed so the give-way vessel can predict its position, but must take action if a collision becomes inevitable.

How should you secure a boat to a dock cleat using a line?

Answer: Make one full loop around the cleat base, then cross in a figure-eight, and finish with a locking hitch

The cleat hitch (loop, figure-eight, locking hitch) distributes load evenly and can be released quickly even under tension.
