Who is the first filipino seaferer's onboard in vessel?

Ancient Malays and ancient Filipino tribes are called the "Austronesians". Now, closely related and both were skilled seafarers. China, Indonesia and Taiwan, are two places of origin for the ancient Filipino and ancient Malay seafarers. Because, at first people thought that the ethnic Malays sailed from Indonesia/Malaysia and up to the Philippines. There's one very good term I can use to describe this, "bogus". Because, Malays and Filipinos share an origin in Taiwan. They reached the Philippines, and then the Indonesian archipelago. They sailed aboard a boat called the "balangay". Ancient villages in the Philippines are called "barangays", based on these seafarers.
