Funafuti is the only port, but there is a deep-water berth in the lagoon at Nukufetau. The merchant marine fleet consists of two passenger/cargo ships ''Nivaga III'' and ''Manu Folau''. The ''Nivaga III'' and ''Manu Folau'' provide round-trip visits to the outer islands every three or four weeks, and travel between Suva, Fiji and Funafuti three or four times a year. The ''Manu Folau'', a 50-metre vessel, was a gift from Japan to the people of Tuvalu.
