rafts and canoes(waka)

 People made rafts and dugout canoe if people would travel it would have to be limited to the islands that are next to each and that can see each other in plain site.Rafts can carry lots of people and can carry heavy loads  but their slow , dugout boats are faster but can only carry a few people.Both of them came unsafe for longer to have big crossings -the rafts would sink and the dugout boats would tip over if a big wave comes by.The high sea would easily push people of the rafts.   

 Outrigger canoes have double hulls.Hulls are really safe because they can’t flip over and they can protect you if a big wave comes it would not flip because of double hull the double hull makes the boat( outrigger canoe)would
