The term Malayan Sailboat is composed of two words, PROA (4 letters) and Prahu (5 letters). PROA is a type of boat originating from the Malay Archipelago, which is a group of islands in Southeast Asia. It is characterized by its asymmetrical hulls, with one hull being much longer than the other. Prahu is another type of boat from the same region, which is typically larger than the PROA and is used for fishing and trading.
