Knabat bogolu is a type of traditional war vessel from Mentawai islands, west Sumatra, Indonesia. This vessel is shaped like a kora kora, but with different outrigger boom placement. Like kora kora, it also has deckhouse at the center of the hull. It has two main booms which slope down to the float (katir in Malay language) and each has an accessory boom. A boom-spar is located above the vessel, one end of which rests on the roof. The float (katir) is double on each side. It has 2 masts, equipped with tanja sail. The stern of the vessel is more highly arched than the bow. Both the bow and the stern had decorative tufts and ropes.
