What is NAICS 33661
NAICS code 33661 covers the Ship and Boat Building industry, which includes establishments primarily engaged in operating shipyards or boat yards. These facilities are equipped with drydocks and fabrication equipment capable of constructing ships, defined as watercraft intended for commercial, industrial, or governmental use, as well as boats designed mainly for personal or recreational use. Businesses in this sector manufacture a wide range of vessels, including cargo ships, passenger ships, barges, and various types of boats like motorboats, kayaks, and inflatable boats. The industry also encompasses repair, conversion, alteration, and specialized services such as ship scaling and prefabrication of ship sections. Government agencies contract with these businesses to meet critical needs for naval defense, transportation, emergency response, and scientific research, relying on their expertise to ensure vessels meet stringent operational and safety standards.
