1 A decked sailing vessel of very shallow draught used for the transport of small quantities of freight on the Norfolk Broads in England. They have a considerable beam in relation to their length and are fitted with a single mast carrying a large loose-footed gaff-rigged mainsail and no headsails. The mast is normally stepped with its heel on deck and supported in a lutchet, similar to a tabernacle, so that it can be lowered to the deck when passing under bridges, etc.
