Model of a bedar luang sudu, a large wooden sailing junk, used to carry cargo. The hull consists of wooden carvel (flush laid) planking fastened to a series of frames by dowels. It contains a projecting prow, a dandan (square ended projection) over the stern, keel, mast steps, decking and three sails.
The term bedar encompasses a group of boats usually carrying one or two Chinese junk style sails and a European jib. The dandan is a typical feature and is usually either latticed or decked and covered by a matting coop which acts as a shelter for crew. The projection at the bow can vary in length but this is a particular feature of the bedar luang sudu.
