The term 'Lateen-rigged Arabian sailing vessel' refers to a type of boat known as a DHOW, which is a traditional Arab sailing vessel with a triangular sail. The lateen rig is a type of sail that is triangular in shape and is attached to a long yardarm, which is then attached to the mast. Dhows have been used for centuries in the Arabian Gulf and Indian Ocean regions for fishing, trading, and pearl diving.
