Portlands wooden hull was built by the New England Company in Bath, Maine. The 1200-horsepower vertical-beam steam engine was constructed by the Portland Company, with a bore, or cylinder diameter, measuring 5feet across, together with a 12abbr=onNaNabbr=on stroke. The ship's two iron boilers were constructed at the Bath Iron Works, also in Bath, Maine.
Portland was built for the Portland Steam Packet Company (later renamed Portland Steamship Company), at a cost of $250,000, to provide overnight passenger service between Boston and Portland. She was one of New England's largest and most luxurious paddle steamers in existence at the time, and after nine years' solid performance, she had earned a reputation as a safe and dependable vessel.
On November 27, 1898, Portland, having departed Boston earlier, was en route to Portland, Maine, following her traditional route. Unbeknownst to the crew, a powerful storm system was quickly traveling north, and Portland, despite her reputation as a remarkably safe vessel, was ill-equipped to handle such extreme conditions.
At some point during the storm, Portland sank off of Cape Ann with all hands, the exact number of which cannot be determined, as the only known passenger list went down with the ship. Initial newspaper accounts at the time estimated the loss as from 99 to 118 persons.[2] [3] The bodies of only 16 crew and 35 passengers were ever recovered, but present-day estimates are that the Portland was carrying, in total, from 193 to 245 persons, including 63 crew.[4]
Her loss represented New England's greatest steamship disaster prior to the year 1900.[5]
The shipwreck is lying below the surface of the Atlantic Ocean near Gloucester, Massachusetts, at an undisclosed location within the federally-protected Stellwagen Bank National Marine Sanctuary. The site was first located in 1989 by John Fish and Arnold Carr of American Underwater Search and Survey. The find was confirmed in 2002 by a National Oceanic and Atmospheric Administration expedition that used ROV's to photograph the wreck.[6] The wreck was added to the National Register of Historic Places in 2005.[7]
In 2008, five Massachusetts scuba divers became the first to reach the steamship, also known as the "Titanic of New England".[8] The divers made three successful dives, and reported that the wreck was strewn with artifacts, like stacks of dishes, mugs, wash basins and toilets, but no human remains. They did not, however, explore below the deck because of the danger. Because of the depth of the wreck site, they reported that some of their dive lights imploded, and they could only explore the site for 10–15 minutes before needing to return to the surface. The divers "were unable to retrieve artifacts" due to rules in place at the Stellwagen Bank National Marine Sanctuary.
