Once the building of the boat is completed, the boat's owner will host a large launching ceremony. To celebrate, Tao women wear their agate beads necklaces and octagonal wooden hats a few days prior to the actual event. On the actual day of the launching ceremony, the Tao people gather and slaughter pigs as sacrifice, and the boat owner offers meat and taro to all of the families in his community. The men, dressed in traditional garb, circle the launching boat performing ceremonial rituals to ward off evil spirits before sending it into the water. They also throw the boat in the air several times prior to launch. The ceremony is deemed complete once the boat has remained afloat.
