The drone camera could relay footage to a rescue boat and may even be possible to speak through the drones to the person in difficulties, advising them what to do.
Drones of the type to be trialled at Muriwai this summer cost $4000-$5000 and about 20c an hour to run on rechargeable batteries. If they prove effective in rescues, the public might well ask whether they could not be in the air constantly on weekend when beaches are thronged.
They would seem ideal for shark patrol and spotting rips as well as augmenting the eyes of lifeguards trying to monitor swimmers beyond the breakers.
For that level of safety, donors and ratepayers would surely provide additional funds to provide surf clubs with them.
Muriwai will be training its members to use the drones this summer and Surf Life Saving New Zealand is treating the trial as a pilot for a national programme. So the day might not be far away when the sight and sound of a hovering drone becomes an accepted company at our beaches - so long as they are identifiable of course.
The search and rescue benefits of drone technology will not be confined to the sea, on land they can search far more closely than a plane and far more cheaply than a helicopter.
They are going to be more than a new toy.
