The Annapolis Boat Shows, Inc. will conduct in-water operations in support of the annual United States Sailboat and United States Powerboat Shows in Annapolis Harbor at Annapolis, MD through October 29, 2021. Temporary pilings, floating docks, and submerged electrical cables will be installed in the northwestern area of Annapolis Harbor. To support the Annapolis Harbor in-water operations, long tows will occur across the Severn River during the following dates in 2021: (a) October 3-6; (b) October 18-21; and (c) October 25-29. During these periods, mariners are urged to use extreme caution when transiting the area and to operate vessels at a reduced speed that allows a safe course and minimizes wake near the towing operations. Information regarding special anchoring restrictions in Annapolis Harbor in the event of severe weather during this period should be directed to the Annapolis City Harbormaster’s Office on marine band radio VHF-FM channel 71 or telephone (410) 263-7973.
