A balangay, or barangay, is a type of lashed-lug boat built by joining planks edge-to-edge using pins, dowels, and fiber lashings.
The Venetian chronicler Antonio Pigafetta, who was with Ferdinand Magellan when setting foot in the Philippines in 1521 called the native boats balangai or balanghai.
[6] In the Visayas and Mindanao, there are multiple names for balangay-type boats, including baloto (not to be confused with the balutu), baroto, biray, lapid, tilimbao (or tinimbao).
[6][12] Cargo-carrying versions of balangay with high sides and no outriggers (which necessitated the use of long oars instead of paddles) were also known as bidok, birok, or biroko (also spelled biroco) in the Visayas.
And these banks are placed in counterweights (outriggers), which are made of a very large bamboo plant found on all the Philippine Islands of the West.
"In Tagalog regions, the balangay or barangay has the same functions as in the southern islands but differ in that it is constructed through the sewn-plank technique, rather than through dowels.
The raiders were regularly attacking coastal settlements in Spanish-controlled areas and carrying off inhabitants to be sold as slaves in markets as far as Batavia and the Sultanate of Gowa.
[10][19][20][21] Notable leaders of these defense squadrons include Don Pedro Estevan, a principalía of Tabaco, Albay; and Julián Bermejo, an Augustinian friar who commanded ten balangay and established an alarm system using a line of small relay forts in southern Cebu.
The most significant was the Battle of Tabogon Bay (modern Tabgon, Caramoan) in 1818, where the combined fleets of Estevan and Don José Blanco defeated around forty Moro warships led by Prince Nune, the son of a sultan from Mindanao.
The 1818 victory led to increased usage of defense fleets and the reduction of Moro raids to only sporadic attacks on isolated fishermen or smaller villages until their eventual suppression in 1896.
Traditionally, the planks and other ship parts were shaped with straight (dalag) or curved (bintong) adzes hammered with a mallet called a pakang.
Instead, they have a central plank fitted with three parallel lines of thin lugs which serve as additional attachment points for lashings.
They are locked in place with wooden dowels or pins (treenails) around 19 cm (7.5 in) long slotted into holes drilled into the edges of the strakes.
[15][13][22] The second stage is known as os-os or us-us, which involves lashing the planks very tightly to wooden ribs (agar) with fiber or rattan ropes.
The ropes are tied to holes bored diagonally into lugs (tambuko), which are rectangular or rounded protrusions on the inner surface of the planks.
A total of nine wooden boats were accidentally found by locals searching for alluvial gold on land near the Masao River.
More modern methods using accelerator mass spectrometry carbon-14 dating yielded more reliable results ranging from the 7th to 10th centuries CE.
Having originally been discovered by treasure hunters, the early excavations of the site in the 1970s and 1980s suffered from poor written and photographic documentation and conservation measures.
The Balangay was chosen so that the "future generations of Filipinos will recognize the invaluable contribution of their forefathers in shaping the country's maritime tradition and in passing on the values of solidarity, harmony, determination, courage and bravery.
[35] In 2009, the Kaya ng Pinoy Inc. that conquered Mount Everest in 2006 announced plans to re-construct a balangay boat, with the help of Sama-Bajau (Sama Dilaya) and other tribal members who retained the lashed-lug boat-building techniques which were mostly lost in other islands.
The balangay's voyage traced the routes of Filipino Ancestors during the waves of Austronesian settlement through Maritime Southeast Asia and the Pacific.
They journeyed from Manila Bay to the southern tip of Sulu, stopping off at numerous Philippine cities along the way to promote the project.
[38][41] The second leg of the voyage (2010–2011) saw the balangay boats navigate around South East Asia – Brunei, Indonesia, Malaysia, Singapore, Cambodia, Thailand and up to the territorial waters of Vietnam before heading back to the Philippines.
[38][41] The balangay was navigated by the old method used by the ancient mariners – steering by the Sun, the stars, the wind, cloud formations, wave patterns and bird migrations.
[38][41][42] The organisers say that the voyage "aims to bring us back to the greatness of our ancestors and how colonialism robbed these away from us and produced the Filipino today".
It also displays the cultural materials such as human and animal remains, hunting goods, jewelries, coffins, pots and other items associated to the boat.
