The tugboat’s engine had overheated at the weekend while trying to salvage the Oceanfresh fishing vessel MV Wairau, stuck on the reef in Rutaki.
Toa had to be towed back into the harbour by Vision.
Cook Islands Ports Authority general manager Nooroa (Bim) Tou said: “Vision is the only boat we can rely on at the moment to assist with ship movements inside the harbour basin.”
Toa’s captain was onboard to give directions and advise Vision’s skipper Keith Christianson of orders from the pilot on the tanker.
There are two ways piloting the ship by stern in (weather pending) or bow inwards and start turning, said Tou.
“Noting also the tallest point of the vessels is the bridge and its aerial mast that at times breaches the aviation flight height restrictions at the international berth terminal.”
“Having the vessel stern south moves the vessels highest point further south without compromising the flight path height restrictions.”
