Harbor Patrol & Marine Units

Harbor Patrol & Marine SAR Response Protocols

Standard operating procedures for open-water, coastal, and inland waterway rescue

Step-by-step operational framework for deploying harbor patrol vessels, rescue watercraft (PWC), and marine law enforcement dive teams into aquatic emergency scenes.

  1. Initial Mayday Verification & Datum Establishment Logging VHF Ch. 16 distress calls, recording GPS coordinates, and establishing last known position (LKP) and corrected datum.
  2. Dynamic Search Pattern Deployment Executing expanding square, sector (psi), or parallel trackline search patterns accounting for wind leeway and tidal set.
  3. Surface Rescue & Drowning Triage Deploying rescue swimmers or PWC operators for active water rescue, applying spinal immobilization in water, and initiating CPR/AED protocols.
  4. Towing, Salvage & Safe Handoff Rigging emergency towing bridles, dewatering swamped vessels, and transferring rescued mariners to shore-based EMS.

Marine Unit Capabilities & Specialized Watercraft

Heavy patrol boats, rescue watercraft, and public safety dive teams

Surface Intercept

Harbor Patrol & Fireboat Units

Heavy-duty, all-weather patrol vessels equipped with radar, FLIR thermal imaging, fire suppression monitors, and advanced marine radios.

Rapid Shallow Water

Rescue Watercraft (PWC) Teams

Sled-equipped personal watercraft capable of rapid surf zone entry, swiftwater rescue, and maneuvering in shallow or obstacle-laden waters.

Subsurface Recovery

Public Safety Dive & Sonar Units

Scuba-certified recovery divers and side-scan sonar operators specializing in submerged vehicle recovery, evidence searches, and underwater body recovery.

USCG Datum, Side-Scan Sonar & Drift Vector Framework

Maritime drift calculation, acoustic bottom imaging, and federal interagency coordination

Aquatic rescue operations require precise drift vector modeling using NOAA tide tables, wind leeway calculations, and high-resolution acoustic imaging.

Drift & Current Modeling

Leeway & Tidal Set Calculations

Integrating surface current vectors, wind direction, and object-specific leeway coefficients to accurately predict object and person drift paths over time.

Acoustic Underwater Search

Side-Scan Sonar & ROV Mapping

Deploying tow-fish side-scan sonar and remotely operated vehicles (ROVs) to map lakebeds, ocean floors, and river bottoms with acoustic imagery.

Advanced Marine Tactics: Tidal Rapids, Night Towing & Subsurface Recovery

Extreme current navigation, dark-water towing, and deep-water recovery operations

Complex marine environments demand advanced seamanship for navigating turbulent tidal gates, conducting secure night-time vessel tows, and managing deep-water recoveries.

Heavy Current Navigation

Tidal Inlet & Rip Current Operations

Navigating constricted tidal rapids and heavy coastal surf zones utilizing specialized hull designs, twin-screw maneuvering, and tethered swiftwater rescue boats.

Nighttime Operations

Black-Water Towing & FLIR Scanning

Executing nighttime vessel tows in zero-visibility conditions using radar overlay, thermal infrared (FLIR) horizon scanning, and deck-mounted searchlights.

Subsurface Search

Black-Water Dive & Tethered Grid Searches

Conducting zero-visibility underwater searches using tethered circular grid patterns, diver-held communications, and surface-supplied air systems.

Specialized Aquatic Operations: Swiftwater Dams, Mass Casualty & HAZMAT Spill Response

Hydraulic keeper rescue, mass-casualty triage, and fuel containment protocols

When marine emergencies escalate into riverine hydraulic traps, mass casualty sinkings, or hazardous chemical spills, specialized tactical protocols govern emergency response.

Riverine Hazards

Swiftwater & Low-Head Dam Extrication

Executing throw-bag deployment, tension-diagonal rescue lines, and tethered boat maneuvers to extract swimmers trapped in recirculating hydraulic keeper boils below low-head dams.

Multi-Patient Triage

Water Rescue Mass Casualty Triage

Adapting simple triage and rapid treatment protocols for water-borne survivors, establishing dockside hypothermia rewarming sectors, and managing immersion shock victims.

Environmental Protection

HAZMAT Containment & Fuel Spill Control

Deploying sorbent and containment booms, vapor suppression blankets, and specialized marine PPE when rescue operations coincide with burning vessels or toxic cargo spills.

Maritime Safety & Navigational Hazard Notice

Aquatic Hazards: Rapidly changing weather, hypothermic water temperatures, shifting shoals, and heavy commercial vessel traffic pose extreme dangers to rescue crews. All marine operations must comply with USCG Navigation Rules (COLREGS) and local command safety limits.

🚔 Law Enforcement

Law Enforcement Marine Patrol

State wildlife and boating agencies, sheriff's marine units and harbor police enforce boating law and are often first on scene for capsizings, overdue boaters and persons in the water on inland lakes and coastal waters.

When to request a law enforcement unit

  • Overdue boater or vessel on a lake, river or bay.
  • Boating accident with injuries or missing persons.
  • Shoreline and on-water search coordinated with the Coast Guard.
  • Securing a water scene for divers and investigators.

Coordination tips

  • Notify the Coast Guard sector on navigable waters; they can issue marine broadcasts and coordinate assets.
  • Collect float plans, launch-site vehicle information and last cell activity early.
  • Use NASBLA BOAT-credentialed crews where available for night and heavy-weather operations.
