BOSTON: Want to learn about American history? Take a boat ride in Boston Harbour — and get ready to listen as well as look. The ‘Birth of a Nation’ cruise highlights the historical significance of Boston Harbour before and during the American Revolution. An audio tour features stories about episodes like the Boston Tea Party, Paul Revere’s ride and the Battle of Bunker Hill.

From the top deck of Seaport Belle, a replica steamship, passengers can peer down the channel to the right and imagine tea crashing into the water during the Boston Tea Party. Actors portraying characters from the period explain on the audio tour how in 1773, colonial activists boarded East India Company ships and dumped 1,800 pounds (810 kilograms) of tea overboard in protest of a tea tax imposed by the British.

Also narrated is the tale of Revere’s ride, west from Boston, and his famous warning to colonial leaders: “The British are coming.”

The story notes that Revere was captured by British soldiers before he left Lexington.

“He got caught,” said Steve Woods, visiting Boston from England and taking the cruise with his wife and daughter. “I didn’t know that.”

The tours depart from Rowes Wharf and are run by Massachusetts Bay Lines Inc.

Airplanes rise from Logan International Airport as Seaport Belle turns away from the South Boston docks and heads directly toward Charlestown, home of Bunker Hill and the USS Constitution.

The steamship, which runs on the hour during the day, stops briefly in the Charlestown Navy Yard. Passengers can get off and return on any future tour later in the day.

Along the tour, don’t be fooled by the laundry detergent bottles bobbing in the harbour. Those are lobster-pot markers; they’re cheaper than wood buoys.

Long after the tea was dumped, Boston Harbour became the dirtiest in the nation because of sewage. But it has undergone a $4.5 billion cleanup since the late 1980s. A decade ago, the 34 harbour islands were added to the National Park system.—AP
