Marine Unit

The Green Bay Police Department (GBPD) Marine Unit patrols the Fox River within the city limits and the "lower" bay of Green Bay. You will see GBPD Marine Officers patrolling these federally regulated waterways at various times during the season.


Our mission is to protect and provide a safe environment on the water which may include assisting disabled vessels, working to provide maritime support during Dive Team/Special Weapons and Tactics (SWAT) operations, as well as aiding in search and rescue incidents.

We work closely with the United States Coast Guard (USCG) and USCG Auxiliary, the Wisconsin Department of Natural Resources and Green Bay Metro Fire Department in these emergency operations.

Unit Composition

Lieutenant Jordan Atlas is the Unit Supervisor that oversees the day to day operations and the patrols that occur throughout the season.

The Marine Unit is comprised of 12 boat operators trained in maritime law and advanced operations to include:

  • Enforcement of municipal, state and federal laws
  • Navigation
  • Safety inspections
  • Search and rescue
  • Vessel contacts

The Marine Unit works with SWAT in tactical operations to include high risk water born scenarios.


The Marine Unit consists of two vessels, including:

  • Number 109 which is a 2006 Zodiac (30 foot) powered by twin 250 horsepower Mercury Verado outboard engines
  • Number 165 which is a 2005 Safe Boat (25 foot) powered by twin 225 horsepower Honda outboard engines

Safe Boat

The department purchased the Safe Boat from United States government surplus in 2018 after it was decommissioned by the USCG. After receiving a new bright blue paint job from its original USCG orange it has a new home on the Fox River.

Unit Responses

The Marine Unit has responded to numerous calls for boater assistance ranging from disabled boats to vessels sinking. The Marine Unit has responded to disturbances on the river, maintained crime scenes, investigated boat crashes and made arrests on intoxicated boaters.

Operation Dry WaterOperation Dry Water

The Marine Unit wants everyone to have a safe and successful season. Recreating on the water and stopping along the City Deck or other piers to visit local restaurants can be fun for the whole family but just like on land if you’ve had too much to drink please have a designated driver. 

The Marine Unit partners with the USCG yearly for an educational campaign "Operation Dry Water" where the statistics of boating injuries related to alcohol are shared with the public. Inevitably there are those who still put themselves and others at risk and are arrested for Operating While Intoxicated.

Department of Natural Resources Support

The Green Bay Police Department Marine Unit would not be possible without the fiduciary support of the Wisconsin Department of Natural Resources (WI DNR). Current state statutes make it possible for reimbursements up to 75% for equipment and patrol hours that local law enforcement agencies spend providing law enforcement on Wisconsin rivers and lakes.

Dignitary Security Details & Event Support

The Marine Unit has been asked to support dignitary security details on and around the waterways of Green Bay, and be the foremost authority at large events to include Fire over the Fox (4th of July), Nicolet Bank’s Tall Ships Festival, and the Dragon Boat Races a fundraising event for the Boys and Girls Club of Greater Green Bay.
