How did double-hulled voyaging canoes withstand long ocean journeys?

Double-hulled voyaging canoes were remarkable feats of engineering that allowed Polynesians to traverse thousands of miles of open ocean. These vessels, which could reach lengths of 100 to 150 feet (30 to 45 metres), were constructed from numerous small wooden components.1

Rather than using rigid fasteners, the builders skillfully fitted these components together and secured them using lashings made from various types of vegetable fibre, such as coconut, hibiscus, pandanus, or banyan bark. This method of construction provided the necessary flexibility for the craft to withstand the constant pounding of wind and waves during long-range voyages. Additionally, because these canoes were narrow, the double-hull design was essential for providing the stability required for seaworthy travel across the Pacific.12
