A Kerikeri man, who spent a year looking for his family's dream boat, could only stand and watch it burn to the waterline on Thursday last week.
The blaze on Thursday destroyed the 8.5m Sea Ray fibreglass launch, which had been moored just off the Rangitane boat ramp.
Its owner, who did not wish to be named, was at home nearby when he saw smoke coming from the boat about 10.35am and raised the alarm.
The Kerikeri Fire Brigade responded with two appliances and a tanker but could do little to save the boat.
Deputy Chief Fire Officer Greg Imms said the launch was too far offshore for hoses to reach, and an attempt to take firefighting equipment out in borrowed dinghies was unsuccessful. In any case, the boat was burning to the waterline when firefighters arrived.
