    let's hope the dev isn't one used to targetting generation Z's wasters, or the thing will just fly around pulsing RGB rainbow effects, find the drowning person, then hover over them while livestreaming it on twitch with the caption "Sink or swim? In at the deep end... Lolz. Donate below to patreon to help save them, or contribute to a gofundme page to help recover and repatriate the body.

    Re: Royal Navy tests rescue drones for 'man overboard' accidents

    There are some really good, wearable man-overboard systems that have trackers on them. I'd say this combined with a drone that hovers, drops a floatation aid and guides the rescue crew would be awesome. An advance would be a tethered floatation aid that is attached to the ship. Potentially you could reel them in closer / prevent them from floating further away and prolonging time in the water.

    The first thing you have to consider is whether this will get used for some kind of extreme drone assisted surfing. I'm assuming the Navy Matelots are as bad as the Army's Squaddies.

    Re: Royal Navy tests rescue drones for 'man overboard' accidents

    Perhaps it's only the bigger ships... but I thought if you went over, it cost so much to turn the ship around and pick you up that the Navy would just leave you there - I recall Tony Scott desperately wanting a certain shot for Top Gun, but the sun was in the wrong direction and the captain on CVN65 couldn't justify the expense of turning the ship... until Tony grabbed his personal cheque book and paid the $25,000 out of his own pocket.

    If it's true, a drone simply hovering over you wouldn't do much if there's no rescue coming anyway.

    A lot of these large ships have outboard craft to deploy and retrieve but if they can't find the person because the ship was moving too quickly and the combination of current and ship speed means they only have a limited time to try and find them before having to return to the ship else be lost themselves. However, upon alarm of man overboard a drone can be deployed to find them and either be a beacon or drop a tracked bouyancy aid then RTB then finding them with the outboard craft would be rapid and they can return to the larger ship much quicker.

    Frankly, I don't know why everyone isn't issued with a bracelet/anklet that is like those old Loc8tor beacons where you can send out a pulse and measure the response to home in. All that R&D and drone budget could be cast aside with just a bracelet that just reflects an RF signal for homing... (edit: how to disparage the 1 over board person from the hundreds of others on a ship? You don't, you measure from the ship in a localised area with a low power squirt and then can alarm when one moves out of the range the outboard just uses a directional RF so doesn't pick up the other sailors on the ship)

    That's what I was thinking of - combine it with the drone and the man overboard gets a floatation aid almost immediately and the RIB crew can easily just head towards the drone. If you could practically tether the floatation aid and the person was able, you could just stop the ship, reel them in, lift up and recover without even deploying a rescue crew. But I am envisioning a nice calm Carribean sea rather than the more likely conditions for a man overboard which is rough and hardly survivable seas.

    Re: Royal Navy tests rescue drones for 'man overboard' accidents

    So much have changed.

    In the old days when the Royal Navy lost something, they put a boat in the water and told the guy to row in circles until we get back.

    Re: Royal Navy tests rescue drones for 'man overboard' accidents

    I'm no expert and I'm sure this has been thought of but from seeing the coastguard/police hovering over the water near me when someone goes overboard (or worse) it takes even fully kitted out manned choppers a while to locate someone in a (comparatively) small body of water vs the ocean. Not sure how these things would work at scale or what happens when they get into range issues.

    Still, one extra set of eyes is better than not having them at all!

    I was reading an article recently about a camera boom that they put on Life Boats that they've been testing which uses deep learning to remove the background noise of waves to isolate inconsistencies to find missing persons. Maybe it works similarly?

    If they use a bigger drone it can do the recovery as well.
    And when it's not scooping up drunken sailors who have had one too many scoops it can carry two Royal Marine backpacks ashore at a time rather than one.

    The problem is a military vessel will not want its crew wearing things where the enemy can find them using RF scanning. Can you imagine that. Not only spotting the ship but then working out the best place to aim the missile at for maximum effect? That's not going to happen surely?

    I don't think that'll be much of a concern, the ship will be a substantially large enough ping contact that hundreds of sailors wearing something that reflects a band of RF would be noisy enough that they wouldn't be able to go "oh look, there's a hundred people, fire there!"

    I would expect most mission critical systems would have pretty equal numbers of people spread out over a ship so it's not like there'll be a large cluster near engineering etc.
