means a recreational boat, often sizeable and luxurious, used for cruising, racing, or simply being seen aboard.

from From the Dutch 'jacht,' short for 'jachtschip' — literally 'hunting ship,' from 'jagen,' to hunt or chase. These were fast, light vessels the Dutch navy used to chase down pirates and smugglers. The pleasure association arrived in the 17th century when the Dutch gave one to the newly restored English king Charles II, who liked it so much he made yachting a royal hobby — and the chase-boat quietly became a status toy.
