A superyacht is a privately or commercially operated luxury yacht (motor or sail powered), which is professionally crewed and has a load line length of 24 meters and above. Some yachts are either used exclusively by their owners or are available part-time for commercial charter, while others are operated all year round as charter businesses. The number of very large yachts has grown rapidly since the 1990s and increasingly only yachts above 65 meters (213ft) stand out among other luxury yachts. The average length of new builds is around 46 meters.
The term superyacht began to appear at the beginning of the 20th century when wealthy individuals constructed large private yachts for personal pleasure like the Jemima F III, which was built in 1908 at 111 feet, the largest motor- powered yacht in the world back then. Between 1997 and 2008, there was a massive growth in the number, size, and popularity of large private or super-sized luxury yachts in the 24-to-70-metre (79 to 230 ft) size range. Luxury yachts, megayachts, or superyachts typically have no real homeport as such, although a yacht must be registered in a port of the country where its flag state is registered.
