The news item is brief, and I'm not sure of the boat brand and size. But it seems likely it was a twin engined boat on the plane. I don't see how else the props and struts would be ripped off after hitting a rope. Maybe there will be more detailed reports once the guys get off the P&O cruise ship in Brisbane tomorrow.
Seems to make a case for a single engined boat with skeg-protected prop!
