Based on the success of the first three new two-deck sightseeing vessels, New York Cruise Lines signed a contract with Gladding-Hearn Shipbuilding to build three more sightseeing vessels, called the Bronx Class. The next set of three vessels added another deck. This third deck included moving the Pilot house up a deck and creating a new second deck lounge with better viewing. These vessels are 165x34x12'-6" in size and certified under subchapter 'K' of 46CFR for 600 passengers.
