A hoy is a small gaff-rigged coasting ship or a heavy barge used for freight, usually with a burthen of about 60 tons (bm). The word derives from the Middle Dutch hoey. In 1495, one of the Paston Letters included the phrase, An hoye of Dorderycht, in such a way as to indicate that such contact was then no more than mildly unusual. The English term was first used on the Dutch Heude-ships that entered service with the Royal Navy.
