Four men were lucky they did not add to the national drowning statistics on Sunday after they floated several kilometres down the Kawarau River on inflatable airbeds.
Queenstown Lakes District harbourmaster Marty Black said the men, believed to be from the United States, had no life jackets, no cellphones and no ''Plan B''.
Mr Black encountered the group on Sunday afternoon above the confluence of the Arrow River and ''strongly advised'' them to get off the river at that point.
''They told me they'd get out, but then I got a call from the bungy operation [AJ Hackett Kawarau Bungy] saying these guys had just floated down under the bridge at Gibbston.''
The men, understood to be staying in Queenstown, would be receiving fines of $300 for not wearing life jackets.
