The MS Mount Washington is a prominent passenger vessel serving Lake Winnipesaukee in Laconia, New Hampshire. As the flagship of the Winnipesaukee Flagship Corporation, it is renowned for its scenic cruises during the spring, summer, and fall months. The ship's home port is at Weirs Beach, from where it makes multiple daily excursions to various ports of call, including Meredith Bay, Center Harbor, Wolfeboro, and Alton Bay. During winter, the vessel remains at its winter home in Center Harbor, protected by bubblers that prevent ice formation around it, and can be pulled from the water as needed for major maintenance. The current MS Mount Washington has a storied history dating back to 1872 with the original paddle steamer of the same name. The original vessel was built by the Boston and Maine Railroad Company, measuring 187 feet (57 m) in length with a beam of 49 feet (15 m). Powered by a 450-horsepower single-cylinder steam engine operating at approximately 26 RPM, it utilized a walking beam mechanism to transfer power to its paddle wheels. It served primarily as a passenger and cargo transporter, capable of carrying over 60,000 passengers in a season. The original vessel was destroyed by fire in 1939 while docked at her home port. A successor vessel was constructed in 1940 using a sectioned hull of the 1888 iron-hulled sidewheeler Chateaugay from Lake Champlain. This twin-screw ship was powered by steam engines from ocean yachts, making her the new Mount Washington. During World War II, her engines and boilers were requisitioned for navy use, but she was later re-powered with diesel engines, earning the "M/V" designation. In 1982, she was extended by 20 feet to expand passenger facilities, increasing her size and comfort, and further modernized in 2010 with new Caterpillar engines for improved efficiency. The MS Mount Washington features a classic design, with her current configuration supporting up to four cruises daily at peak season, including scenic dinner dance cruises. She has played a vital role in the region’s tourism, combining historical significance with modern amenities, and remains a key maritime icon on Lake Winnipesaukee.
