Chamorros of the Mariana Islands in 1521, Antonio Pigafetta recorded that the Chamorros' sailboats far surpassed Magellan's in speed and maneuverability. Similarly, the Spanish priest Francisco Combés, describing the large karakoa outrigger warships of the Visayan Islands in the Philippines, remarked: Outrigger fishing canoes are also used among certain non-Austronesian groups, such as the Sinhalese in Sri Lanka, where they are known as oruwa, as well as among some groups in the Andaman and Nicobar Islands. They can also be found in East Africa (e.g., the ungalawa of Tanzania). The acquisition of the catamaran and outrigger boat technology by the non-Austronesian peoples in Sri Lanka and southern India is the result of very early Austronesian contact with the region, including the Maldives and Laccadive Islands. This is estimated to have occurred around 1000 to 600 BCE and onwards. This may have possibly included limited colonization that have since been assimilated. 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. The technology has persisted into the modern age. Outrigger boats can be quite large fishing or transport vessels. In the Philippines, outrigger boats (called bangka or paraw) are often fitted with petrol engines. The links between seafaring and outrigger boats in the Philippines extend through to political life, in which the smallest political unit in the country is still called "barangay" after the historical balangay outrigger boats used in the original migrations of the first Austronesian peoples across the archipelago and beyond. The Polynesian Voyaging Society has two double-hull sailing catamarans, Hokulea and Hawaiiloa, and sails them between various islands in the Pacific using traditional Polynesian navigation methods without instruments. The Hikianalia and Alingano Maisu are other extant double-hulled voyaging canoes. Terminology and linguistics The German linguist Otto Dempwolff (1934-1938) originally reconstructed the Proto-Austronesian word for "boat" as *waŋkaŋ, and included the reflexes for both *baŋkaʔ and *waŋkaʔ as its descendants. However modern linguists like Robert Blust generally reject this. Mahdi (2016) instead reconstructs four words for "boat" in the Austronesian languages, all ultimately derived from the monosyllabic protoforms *Cu and *baŋ. They are: a) *qaCu - cognates include Squliq-Atayal qasuʔ, Pazeh ʔasuʔ, and Bunun hatoʔ b) *qabaŋ - cognates include
