This Coast Guard profile is courtesy of Ron Perron.
The following technical data on the United States Coast Guard (CG) Sector Baltimore is derived from personal monitoring from my location just outside of Baltimore, Maryland. As stated on the official Coast Guard web site the mission of Coast Guard Sector Baltimore is to effectively and efficiently:
• Maximize unit readiness
• Prevent or respond to incidents
• Understand and address our customers’ needs
• Achieve unity of effort with our partners in order to provide maritime safety, security, accessibility, and environmental protection for the National Capital Region, and the upper Chesapeake Bay and its tributaries.
Coast Guard Sector Baltimore and its subordinate units include:
Aids-to-Navigation Teams in Baltimore; Crisfield; Potomac.
There are Small Boat Stations in Annapolis; Crisfield; Curtis Bay; Oxford; St. Inigoes; Stillpond; and Washington (Bolling AFB).
Coast Guard Station Curtis Bay, in addition to being an active Small Boat Station, also houses the Coast Guard's main shipyard which performs maintenance, upgrades and new boat building for the entire Coast Guard fleet. Due to the shipyard, there's usually a interesting "flow" of out-of-area vessels showing up on the marine channels.
In communications I regularly hear Coast Guard Sector Baltimore, Coast Guard Station Curtis Bay, Coast Guard Station Annapolis. The Coast Guard Sector Baltimore also is assisted by several area Coast Guard Auxiliary aircraft which provide airborne patrols of the Chesapeake Bay area during peak activity times, normally April-October.
The Coast Guard Sector Baltimore area of responsibility covers the entire Chesapeake Bay, which runs roughly from the Delaware/Pennsylvania border down to the mouth of the Bay near Norfolk Virginia. In order to be able to maintain VHF communications over this area they use a VHF repeater which is located atop the main structure of the Chesapeake Bay Bridge, near Annapolis Maryland. The Sector radio operators refer to this location as the " high site"
