Yacht has one of the least phonetic spellings in English, and it is Dutch. English took it in the 1550s as yeaghe, from early Dutch jaght or Norwegian jaght, and spent a century trying to write it before settling on a form that preserves the Dutch ch — a throat sound English does not have and simply drops.
The word is a shortening of Middle Low German jachtschip, literally "chasing ship" — a fast pirate ship, from jagen, "to chase, hunt." So the vessel now associated with leisure is named for pursuit, and English first used it for a ship of state for important personages before the wealthy took it over for pleasure. It belongs to the substantial Dutch nautical layer alongside sloop, deck, dock, cruise, skipper and boss.
