Today, the site presents a representation of the trades and businesses typical of a mid-to-late 19th-century seaport, including those which would have been located on the water's edge and others which would have operated further inland. Trades and skills represented within the village include medicine, general sales, chandlery sales, navigation, life saving, cooperage, blacksmithing, sail making, rigging suppliers, whaling, commercial fishery, oystering, and rope making.

The village also contains a church, seamen's friends site, residences of several periods, and other structures, the vast majority of which are period. Vessel highlights include the last wooden whaleship in the world, a Newfoundland commercial fishing schooner, and a lighthouse tender used to smuggle Jews out of Nazi-occupied Denmark.

The seaport is also home to exhibits of maritime history and art, a planetarium, carefully restored tall ships and historic vessels, and a working preservation shipyard. Demonstrations depict whale boat stations and rowing, period domestic life, life saving techniques, rope making, sail hauling and furling, and sea chanteys.

The seaport offers a planetarium, traditional and interactive exhibits, presentations, field trip programs, interpretive activities aboard the seaport's fleet of ships, outreach programs, summer camps, a playground, children's games and activities, living history demonstrations and reenactors, opportunities to sail or row, steamship and catboat rides, a water taxi, adult and college classes, guided and self-guided tours, and overnight activities.
