Deliver a lightweight floatation device using a toy remote controlled helicopter to sinking person in the sea.
Alternatively model airplanes could be used, but they are not very good at hovering.
I think this could be much faster method of delivery of floatation device compared to lifeguard
running and jumping into the water.
Is Baywatch listening ?
More reliable, perhaps.

Alternatively, a stack of aerobie life rings with a skeet launcher. |
|
| |
I'd guess a lot of rescues have to be made in stormy conditions.
Model helicopters (the controllable ones - not the tiny indoor ones) are hard enough to control in good conditions. |
|
| |
Perhaps a harpoon with a flotation device - doesn't require the standed person to be concious. |

an article I read recently discussed using quadcopter drones to deploy lifesaving equipment to drowning people. Even a small drone could get to the victim faster than an Olympic swimmer. I'll give this a bun, even though technology has surpassed this idea. |
|

I saw a video on that a few months ago. It looked pretty
effective. |
|
| |
Didn't Patent Bending try a couple of methods (I think
a rocket and a cannon) for this purpose? |
|
| |
If the quad floated, it would give new meaning to deploying the lifesaver. |
|
| |
Don't just drop pool toys on me and leave! Tow me
to shore already! |
|

Actually, you probably could make a quadcopter that
doubled as a flotation device. The body would be
made largely of expanded polystyrene with a tougher
shell. |
|
| |
The only problem would be sealing around the
propeller shafts, but that would probably be doable. |
|
| |
Well I think Sweden is trialling or looking at or thinking about autonomous drones equipped with Defribulators for extremely rapid response for heart attacks. So there's a lot of movement in this space. |
|
| |
Lifesavers might be better off with a cannon of sorts that shoots a floating line across the victim who can grab on and be towed back to shore. This could be made with off-the shelf components (and would very much be increased incentive for people to become lifesavers...). |
|
| |
There are quadcopters available that are semi-waterproof, ie they can land in water and, mostly, the motors stay dry-ish (with appropriate water proofing and maintenance of the bearings it all survives nicely). Maybe a contactless magnetic coupling could be used to conduct drive across a waterproof membrane? |
|
| |
//there's a lot of movement in this space// They
wouldn't be much use otherwise. |
|
| |
Waterproof, amphibious quadcopters have been on the
market for at least a year now. I think Flite Test has a
video on one. You'd just need to add a lot more
flotation to that. I recommend aerogel for minimal
extra weight it has to carry. |
|

Cannons would be a fixed target deal but a fishing line tied drone life-ring would have all the advantages. |
