Double-ended Bugis-Makassan pajala-style ship with tripod masts and canted rectangular sails (some of them lowered and stowed on deck), as well as quarter-hung rudders.
This picture is made in 1803 by artist William Westall about a Bugis prahu in the Arnhem coast. The chance comes when Flinders met with Makassan prahu fleet when they're collecting tripang. This prahu weights 25 tons and armed with small cannons.
