Question 2

Which statement about wildlife watching from a boat is correct?

Accepted Answer

Maintaining a safe distance and avoiding sudden movements minimizes stress to marine wildlife

Answer

Question 3

What is the purpose of a Marine Sanitation Device (MSD) Type I?

Accepted Answer

It treats sewage to reduce bacteria levels below a legal threshold before discharge

Answer

It stores sewage in a holding tank until it can be pumped out ashore

Answer

It incinerates sewage waste using engine heat

Answer

It converts sewage into gray water through chemical neutralization

Question 4

How does boat engine exhaust contribute to water quality problems?

Accepted Answer

Hydrocarbons and nitrogen oxides from two-stroke engines dissolve in water and harm aquatic organisms

Answer

Exhaust gases create acid rain that directly acidifies local water bodies below the boat

Answer

Exhaust raises water temperature significantly in confined marina areas

Answer

Carbon dioxide from exhaust causes immediate hypoxia in fish near the vessel

Question 5

What should a boater do if they observe someone else illegally dumping garbage overboard?

Accepted Answer

Note the vessel description and registration number and report to the Coast Guard or environmental authorities

Answer

Confront the violator directly and demand they retrieve the garbage

Answer

Answer

Ignore it since enforcement is the Coast Guard's responsibility and reporting is futile

Question 6

Which practice most effectively reduces underwater noise pollution that affects marine mammals?

Accepted Answer

Slowing vessel speed and reducing unnecessary engine idling near known marine mammal habitats

Answer

Painting hull interiors with sound-absorbing coatings

Answer

Using high-frequency depth sounders instead of low-frequency ones

Answer

Operating only during daylight hours when marine mammals surface more frequently

Question 7

What is the recommended action when boating near nesting shorebirds on a beach or island?

Accepted Answer

Maintain at least 150-300 feet distance and do not land or anchor near nesting colonies
