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 (a hoy of Dordrecht),[2] 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.
