The town of Sibu can be assessed by oceangoing vessels for 80 miles (130 km), while an additional 100 miles (160 km) of the river can be assessed by shallow-draft craft. The remaining parts of the river, leading into the Sarawak interior, can only be assessed by small canoes. Speedboats and longboats are the major form of transport between Kapit and Belaga. Transportation above Belaga to the Balui River requires longboats. The Rajang River is also used for transporting logs. During the monsoon season, some areas of the interior are accessible only by river. Meanwhile, in the towns downriver, market traders are often affected by floods.Richard C, 2010. Page 9
