Traditionally the war canoe was highly tapu (sacred). No cooked food was allowed in the craft and the waka had to be entered over the gunwales, not the bow or stern, which were highly decorated with powerful symbols. Canoes were often painted with black or white with black representing death. The main colour was red which stood for tapu. Sometimes a waka would be placed upright as a marker for a dead chief with the curved bottom of the hull carved. Māori told missionaries during the Musket Wars that battles between waka took place at sea with the aim being to ram an enemy's waka amidships at high speed. The ramming vessel would ride up over the gunwale and either force it under water or cause it to roll over. The enemies were either killed, left to drown or captured to be used in cannibal feasts or as slaves if they were female. This description matches the attack on the ship's boat of Abel Tasman in Golden Bay in 1642 when a Māori catamaran rammed a cock boat and four Dutch sailors were killed.
