U.S. Coast Guard stations and sector commands in Puerto Rico protect the state's navigable waterways, ports, and coastline through search and rescue operations, maritime law enforcement, and boating safety programs. Federal oversight is coordinated through the Coast Guard District responsible for the region.

Residents of Puerto Rico who operate recreational or commercial vessels should be familiar with the local Coast Guard sector's jurisdiction, contact information, and any state-specific boating regulations that apply to their waterways.

Residents and boaters in Puerto Rico should keep the local Coast Guard Sector's non-emergency contact number on hand, ensure their vessels carry all required safety equipment, and register boats as required under state and federal law. For emergencies on the water, contact the Coast Guard immediately on VHF Channel 16.
