Yacht
A yacht is a recreational boat or ship. ... In modern use the term designates two rather different classes of watercraft, sailing and power boats. Yachts differ from working ships mainly by their leisure purpose, and it was not until the rise of the steamboat and other types of powerboat that sailing vessels in general came to be perceived as luxury, or recreational vessels. Later the term came to encompass motor boats for primarily private pleasure purposes as well. [Yacht. Wikipedia]
