In 2018, Pirate Ships of Baltimore was unveiled as the newest attraction in the Inner Harbor. Located between the World Trade Center and the National Aquarium Pier 3, the dock houses a fleet of 12 electric boats that hold up to six passengers each. A clean energy alternative, the Electric Pirate Ships operate on lithium-ion battery power, fueled by solar energy and provide fun for children and adults of all ages who want to storm the harbor.
