OBS Defensive Driving Techniques 3

Question 1

A defensive boater approaching a marina entrance should:

Accepted Answer

Reduce speed, watch for swimmers and divers, and follow posted signs

Answer

Marina areas have swimmers, divers, and slow-moving vessels, so slow speed and heightened awareness are essential.

Question 2

When two power-driven vessels are on crossing courses and risk collision, which vessel must give way?

Accepted Answer

The vessel that has the other on its own starboard side

Answer

Under COLREGS Rule 15, when two power vessels cross, the vessel that has the other on its starboard side is the give-way vessel.

Question 3

What should a boater do if their engine fails in a shipping channel?

Accepted Answer

Attempt to anchor, display distress signals, and contact the Coast Guard

Answer

Anchoring (if possible), displaying distress signals, and contacting the Coast Guard ensures others are aware of your emergency situation.

Question 4

The 'two-minute rule' in defensive boating refers to:

Accepted Answer

Running bilge blowers for two minutes before igniting gasoline engines

Answer

Running the blower for at least four minutes (commonly called the two-minute rule) clears fuel vapors before starting a gasoline inboard engine.

Question 5

When operating near a large commercial vessel, why should you stay well clear even if you have right of way?

Accepted Answer

Large vessels cannot maneuver quickly and may not see small boats

Answer

Large ships have limited maneuverability and restricted visibility, making it dangerous for small boats to insist on their right of way.
