The DC Boating Safety Certificate

Boating on District of Columbia waters is policed by the Metropolitan Police Department (MPD) Harbor Patrol Unit. MPD states that anyone operating a vessel on District of Columbia waterways is required to have a Boating Safety Certificate.

MPD issues the certificate to people who successfully complete its Boating Safety course. The course teaches the legal requirements, the Navigation Rules, safety equipment and the main causes of accidents.

MPD's page does not describe a separate written exam or a pass mark, so this quiz is for learning and review.

How to use this quiz

Practice set 1 covers the DC rules in this guide: the certificate, young operators, life jackets, speed limits, accidents and registration. The other sets cover the national material that every boating course teaches, such as who gives way, navigation lights, sound signals, buoys and required equipment. Study both, because the MPD course covers the legal requirements and the Navigation Rules together.

Operators and renters under 18

The DC harbor regulations, published by MPD, set rules for young boaters in Section 1026.

  • Operating: a person under 18 may not operate a vessel 16 feet or longer unless they have completed a boating safety course approved by the Harbor Master, or are supervised as the rule requires.
  • Renting: no one may rent a vessel to a person under 18 unless they completed an approved course or are under the constant supervision of a qualifying adult.
  • Proof: an operator must have evidence of an approved course with them, or make it available to the Harbor Master at the launch or berthing point.

Life jackets for young crews

When a vessel 16 feet or longer is operated by someone under 18, the operator and everyone else aboard who is under 18 must wear a Coast Guard-approved life jacket of the right size.

How to check that a life jacket fits.

  1. Zip up the front.
  2. Fasten all the buckles.
  3. Pull the side straps snug.
  4. Have someone lift at the shoulders. A good fit stays below your chin.

Life jackets, speed and safe operation

Every boat needs a Coast Guard-approved wearable life jacket for each person on board. Each one must be in good condition, easy to reach and the right size. MPD notes that boats 16 feet or longer must also carry a throwable device.

Between Fletcher's Cove and Little Falls, everyone aboard must wear a life jacket at all times.

Speed and wakes

  • In listed areas, including upstream of Arlington Memorial Bridge, power-driven vessels may not go faster than 6 statute miles per hour.
  • When passing the Alexandria, Virginia, wharf area, the limit is 10 miles per hour.
  • Operators must control their speed and wake to avoid danger or injury to others.
  • You may not jump another vessel's wake within 100 yards of it.
  • Personal watercraft running at 10 mph or faster must stay at least 25 yards apart.

Towing

When you tow a water-skier, an observer other than the operator must be on board, and the observer must be at least 12 years old.

Personal watercraft

Everyone on a personal watercraft should wear a Coast Guard-approved life jacket. PWC riders also follow the DC wake-jumping and 25-yard spacing rules above.

Alcohol and drugs

The regulations ban operating a vessel while under the influence of alcohol, marijuana or any narcotic drug, barbiturate or hallucinogen.

Reporting accidents

The harbor regulations require a written report to MPD after a serious boating accident, such as one that causes a death, an injury, a disappearance or major damage.

SituationDeadline
Death or disappearanceNotify the Harbor Master immediately
Death within 24 hours, injury needing more than first aid, or a disappearanceWritten report within 48 hours
Other reportable accidentsWritten report within 10 days
AB

Most collisions happen when boats cross. The boat with the other on its starboard side gives way.

  1. A: Give-way boat. It turns right and passes behind B.
  2. B: Stand-on boat. It holds course and speed.

Registration and titling

Any vessel that is operated mainly on DC waters must be registered every year with the DC Boat Registration Office at MPD. Registrations can be renewed online.

  • All registrations expire on December 31 each year.
  • The registration certificate must be on the boat and available for inspection whenever the boat is in use.
  • Registration numbers must be at least 3 inches high.
  • A new validation sticker is issued each year and goes within six inches of the number.
  • Under the District of Columbia Boat Titling Act, a registered vessel used mainly on District waters must also get a certificate of title.

MPD's Online Vessel Registration System lets owners renew without visiting an office. MPD sorts boats with propulsion machinery into registration classes by length, from under 16 feet to over 40 feet, and has a separate class for boats without propulsion machinery.
