Fijian company Bluewater Craft has purposely designed and built a pilot boat, 'Unga', to specifically operate in Tonga.
Unlike most pilot boats in the Pacific, 'Unga' has inboard engines and can reach a maximum speed of 25 knots.
'Unga' is 12.7 metres long, 4.3 metres wide and weighs approximately 6.5 tonnes.
