Annapolis Nautical Chart
America's sailing capital sits where the Severn River meets the open Bay. The chart covers the approaches past Greenbury Point, the marked harbor channel into Spa Creek and Back Creek, the Naval Academy anchorages, and the busy waters under the Bay Bridge just north. Watch the shoals off Tolly Point and Hackett Point on the way in — depths drop from 20+ ft in the channel to 2–4 ft close inshore.
