It is understood the launch's owner lives in Christchurch and was bringing a boat from Whangarei to Picton.
"We probably get two or three similar taskings each year, the last one was only a couple of weeks ago, that was a yacht going from Picton to Tauranga."
Because the owner was a Coastguard member, the tow cost him nothing.
"One of the benefits of Coastguard membership is a free assist regardless of which unit you belong too. We did charge him for the fuel transferred. If they are not members we charge them $280 per hour. For example the yacht a week or so ago was not a member and that cost him just over $1000."
People are not charged for "emergency" callouts.
Mr van Tuel said the incident was a good reminder for skippers to ensure they had enough fresh fuel on board.
