A defensive boater approaching a marina entrance should:
Answer: Reduce speed, watch for swimmers and divers, and follow posted signs
Marina areas have swimmers, divers, and slow-moving vessels, so slow speed and heightened awareness are essential.
When two power-driven vessels are on crossing courses and risk collision, which vessel must give way?
Answer: The vessel that has the other on its own starboard side
Under COLREGS Rule 15, when two power vessels cross, the vessel that has the other on its starboard side is the give-way vessel.
What should a boater do if their engine fails in a shipping channel?
Answer: Attempt to anchor, display distress signals, and contact the Coast Guard
Anchoring (if possible), displaying distress signals, and contacting the Coast Guard ensures others are aware of your emergency situation.
The 'two-minute rule' in defensive boating refers to:
Answer: Running bilge blowers for two minutes before igniting gasoline engines
Running the blower for at least four minutes (commonly called the two-minute rule) clears fuel vapors before starting a gasoline inboard engine.
When operating near a large commercial vessel, why should you stay well clear even if you have right of way?
Answer: Large vessels cannot maneuver quickly and may not see small boats
Large ships have limited maneuverability and restricted visibility, making it dangerous for small boats to insist on their right of way.
Which signal indicates a vessel is backing up (moving astern)?
Answer: Three short blasts
Three short blasts on the horn indicate a vessel is operating its engines in reverse.
A defensive boater always checks wake effects because wakes can:
Answer: Capsize small boats, damage docks, and endanger swimmers
Wakes from your vessel can cause serious harm to small boats, people in the water, and waterfront property even outside posted no-wake zones.
