One of the most important technological exchanges of the spice trade network was the early introduction of maritime technologies to India, the Middle East, East Africa, and China by the Austronesian peoples. These technologies include the plank-sewn hulls, catamarans, outrigger boats, and possibly the lateen sail. This is still evident in Sri Lankan and South Indian languages. For example, Tamil "paṭavu", Telugu "paḍava", and Kannada "paḍahu", all meaning "ship", are all derived from Proto‑Hesperonesian "*padaw", "sailboat", with Austronesian cognates like Javanese "perahu", Kadazan "padau", Maranao "padaw", Cebuano "paráw", Samoan "folau", Hawaiian "halau", and Māori "wharau".
