The Polynesians were expert seafarers and fishermen even it is said they found America! . The type of vessel used is an outrigger canoe which gets its stability from a pole that is lowered into the water with two other poles attached. This is called an outrigger and unlike south-east Asia that in Polynesia they don’t have two outriggers. They also made double hulled canoe and asymmetric canoe which had one longer canoe and one shorter. These were one of the first open sea going ships.
