Luzzu while at sea. On 30 October 1948, a luzzu that was being used as a Gozo ferry capsized and sunk off Ħondoq ir-Rummien, Gozo. 23 people were killed. The town of Marsaxlokk is especially famous for the large numbers of luzzu and similar craft operating in its harbour. The luzzu is often considered as a symbol of Malta. Some luzzi have been converted to passenger carriers for tourists although the vast majority continue to be used as fishing vessels. A "kajjik" is similar in appearance and function to the luzzu, but has a square transom instead of a double-ended hull.
