The document discusses two examples of functional arts in Mindanao: the balangay and the vinta. The balangay, a large wooden boat, was essential for trade and migration among pre-colonial Filipinos, capable of carrying 60 to 90 people. The vinta, a smaller sailboat from the Badjao people of the Sulu archipelago, is known for its colorful geometric sails and is primarily used for fishing and transportation.
