From the Upper Chesapeake
There are two ways to approach Baltimore Harbor. At the southern end of the Tolchester Channel, head west up the Brewerton Channel Eastern Extension. It will take you into the Patapsco River and Baltimore. Or, you can bypass the length of the main shipping channel and break off east of Pooles Island and head southwest through the marked channel, leaving the green buoys to starboard as you head south. This channel intersects the Brewerton Channel and Craighill Channel just south of North Point at the mouth of the Patapsco River at R “2B” Q R, and R “4”, which is when you return to red-right-returning mode.

From the south and Annapolis
Follow the various angles of the Craighill Channel north. Just north of Q G “25”, this channel intersects the Brewerton Channel. Head west-northwest alongside Brewerton Channel into the Patapsco River. The Brewerton Channel runs west-northwest up the Patapsco River. The channel swings northwesterly and passes Fort Carroll and then under the Francis Scott Key bridge where it becomes the Fort McHenry Channel. North of the bridge, Brewerton Channel becomes the Fort McHenry Channel and continues to Baltimore. The Curtis Bay Channel branches off to the west at G “1CB” Q G. As you near Fort McHenry, the channel splits again. Take the northern fork into Northwest Harbor East and West Channel, where you’ll find Henderson’s Wharf and Fells Point to north.
