By the end of the 18th century, coinciding with the museum's 1799 founding, Salem was one of the nation's most prosperous seaports, and extensive trading of furs, spices, dyes, and other goods brought much wealth to the region. This long legacy of trade contributed greatly to the foundation and growth of PEM's maritime art collection, which is among the finest of its kind in the country. The collection includes over 50,000 objects, including paintings, model ships, scrimshaw, and more. Many diverse styles and periods of maritime art are on display in the collection, from navigational tools such as sextants to modern marine art, which addresses "nostalgic themes" and represents "the seafaring life of previous times." One significant feature of the currently installed collection is a recreation of a room in Cleopatra's Barge, an opulent yacht which was built by Salem's Crowninshield family and eventually became the royal yacht of King Kamehameha II.
