How did macassans build their boats?

Macassans built their boats, known as praus, using traditional techniques that involved local timber and materials. The construction often featured a wooden frame covered with planks, and the boats were designed for both fishing and trade. They also incorporated sails made from woven palm fibers or cotton, allowing for effective navigation in the waters of the Arafura Sea. The craftsmanship reflected their deep understanding of maritime practices and the local environment.
