Thelorcha is a type of sailing vessel having ajunk rig with a Cantonese or other Chinese-stylebatten sails on a Portuguese or other European-stylehull. The hull structure made the lorcha faster and able to carry more cargo than the normaljunk. The advantage of the junk rig was in its ease of handling and resulting reduced crewing requirement, together with its relatively low cost of construction. Owing to its simplicity, it was also easier to repair. Lorchas were made locally ofcamphor orteak and generally were of 30 to 150 tonsburthen.
