"I took the video of the offending boat pulling out of the one he had T-boned.

"I think it must have been either an electrical fault on the drive-by-wire steering system, or a human fault - whichever way he went the wrong way and careered straight into this multi-million dollar ship."
The witness said their were people on both boats at the time of the crash.
"In the video you can see them coming out onto the duck board to have a look. It all happened within 15 minutes within the end of the show," he said.
An Auckland Transport spokesperson said they knew about the collision and have seen video of it, but the harbourmaster wouldn't be taking any action.

A spokesperson for the Auckland On Water Boat Show said as the incident happened after the vessel had departed the boat show, they were unable to provide comment on the incident.
Pacific Charters said they take bookings for the Quest 2 boat, but the owner was currently out of town.
"We gather it was a Riviera but we don't know quite what happened," a spokesman said.
"It was a wide open bit of water right beside it so it was very strange to see it happen.
"The insurers and Maritime will have to be involved and look into the incident."
Maritime NZ said they were aware of the incident but couldn't comment further due to the investigation being underway.
The Herald has approached the owners of both boats for comment.
