A yacht is a sail- or motor-propelled watercraft made for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a yacht, as opposed to a boat, such a pleasure vessel is likely to be at least 33 feet (10 m) in length and may have been judged to have good aesthetic qualities.
A motorboat or powerboat is a boat that is exclusively powered by an engine; faster examples may be called "speedboats".
A turboshaft engine is a form of gas turbine that is optimized to produce shaft horsepower rather than jet thrust. In concept, turboshaft engines are very similar to turbojets, with additional turbine expansion to extract heat energy from the exhaust and convert it into output shaft power. They are even more similar to turboprops, with only minor differences, and a single engine is often sold in both forms.
A superyacht or megayacht is a large and luxurious pleasure vessel. There are no official or agreed upon definitions for such yachts, but these terms are regularly used to describe professionally crewed motor or sailing yachts, ranging from 40 metres (130 ft) to more than 180 metres (590 ft) in length, and sometimes include yachts as small as 24 metres (79 ft).
