What is the primary reason boaters should avoid anchoring on coral reefs?
Answer: Anchors can physically crush and break coral structures
Anchors and anchor chains can crush, break, and permanently destroy fragile coral structures that may have taken decades to grow.
Which action best describes 'Leave No Trace' principles as applied to boating?
Answer: Removing all waste and minimizing environmental impact on waterways
Leave No Trace means packing out all waste and minimizing your footprint so waterways remain undisturbed for wildlife and future visitors.
How far offshore must a vessel be before legally discharging untreated sewage in federal waters?
Answer: 12 nautical miles
Under federal law, untreated sewage may only be discharged beyond 3 nautical miles, but MARPOL rules restrict it further to 12 nautical miles from shore.
What is 'aquatic invasive species' (AIS) transport most commonly caused by?
Answer: Boaters moving watercraft between bodies of water without proper cleaning
Boats, trailers, and equipment moved between water bodies without cleaning are the most common pathway for spreading aquatic invasive species.
When should a boater use a Type III PFD to help protect manatees?
Answer: Type III PFDs have no connection to manatee protection
PFD type selection is unrelated to manatee protection; manatee zones are protected by speed restrictions, not PFD requirements.
What does the 'Clean, Drain, Dry' protocol require boaters to do?
Answer: Remove all aquatic plants and animals, drain all water, and dry equipment before moving to another water body
Clean, Drain, Dry requires removing visible organisms, draining all water compartments, and drying equipment to prevent invasive species transport.
Which fuel additive is banned in many jurisdictions because it contaminates groundwater near marinas?
Answer: MTBE (methyl tertiary-butyl ether)
MTBE was widely used as a fuel oxygenate but is now banned or restricted in many states because it readily contaminates groundwater and drinking water supplies.
