Areas Covered

The Marine Unit operates seven days a week, 365 days a year, and covers multiple bodies of water. These include:

  • Atlantic Ocean
  • Indian River
  • Intracoastal Waterway
  • Lake Okeechobee
  • Okeechobee Canal
  • St. Lucie River

Deputies also spend many hours conducting drug and illegal immigrant interdiction patrols. With Martin County's close proximity to the Bahamas and miles of uninhabited beaches, patrolling our coastline is a daunting task. 

The Stonegarden Grant

The Stonegarden Grant, awarded by United States Customs and Border Patrol and the Federal Emergency Management Agency (FEMA). has provided the Marine Unit with additional resources to increase proficiency. One of these was the purchase of three forward-looking infra-red (FLIR) cameras that were installed on selected patrol boats. This technology helps Deputies detect thermal heat from vessels or persons that may be in the water awaiting help during nighttime hours.
