NAUTICAL exclamation: ahoy
Ahoy is a signal word used to call to a ship or boat, stemming from the Middle English cry, ‘Hoy!’. The word had fallen into obsolescence before rising from obscurity as the sport of sailing rose in popularity. ‘Ahoy’ can also be used as a greeting, a warning, or a farewell.
Adding the rhyming Irish last name makes this a perfect boat name for celebrating St. Patrick’s day.
