Marine Services

The Marine Services Unit provides law enforcement, search and rescue and boater safety and education services in all waterways surrounding Marin County.

"Rescue One"

The Marine Patrol Unit operates a 32 foot Almar patrol boat, “Rescue One” patrolling the waters of Marin County. The boat is equipped with state of the art technology including a forward looking infrared camera, radar, global positioning system, night vision binoculars, and a directional finder that allows Rescue One to hone in on radio signals to locate distressed vessels. The boat includes a dewatering/fire fighting pump, towlines, rescue equipment, and medical supplies.

The Marine Patrol Unit also operates a 24’ Almar Rigid Hull Inflatable boat powered by twin 150 HP Mercury Optimax outboard engines. The 24’ RHI is a vessel jointly utilized by the Marin Sheriff’s Dive Team. Both of these vessels were purchased by federal and state grants. In addition to the patrol boats, the Marine Unit operates two Wave Runners that were donated by Yamaha to provide water safety. Personal watercraft allow rescue and law enforcement operations in shallow water where patrol vessels are unable to operate.


The Marine Patrol Unit consists of one commander and one full time Deputy. In addtion, there are two Deputies who are assigned to the unit as a part-time, collateral duty. There are 10 marine patrol reserves, a volunteer group, who ride with the full time deputies as support staff. The reserve unit donates over 1,000 volunteer hours per year maintaining and operating Rescue One.

The primary area of patrol extends from Point Bonita outside the Golden Gate Bridge to San Antonio Creek on the Petaluma River. This area encompasses 59 miles of shoreline and over 90 square miles of water within the Marin County border. The unit also provides patrol along the coastal waterways of Marin County from the Golden Gate Bridge to Tomales Bay.
