Overboard - Remote Control--Engine Off

Hi all,

Working on a new important safety device. This device, should you go overboard while your outboard engine is in gear, will shut-down your outboard, without a tether. (That does not mean forget about using the tether).
When I finish the design and have tested it, I'll let my friends here know the real results. That you will have an additional option to shut-down your outboard should rough weather/wave conditions send you into the water with your boat still moving under engine power.

A few such concepts have been discussed here before you may want to do a search. But IIRC the summary of concerns are:

- What makes the device any better than a standard kill cord.
- Issues with standard KC are (a) forgetting or choosing not to wear it (b) UV fatigue (c)accidental shut off when stretching.
- So how does it insure you wear it. Feeling is a WiFi device gets chucked in a locker, when you start the engine it will let you because its on-board
- How does it fair in the elements. This can not fail at the wrong time, either killing engine when you mustn't loose power or failing to when you go over.
- How far can you get from the boat before shut off. Risk of engine strike before shut off?
- How does your crew get back to you? Is there an over-ride or second toggle?
- What if the helm goes to the pub with it in his pocket... can the second mate still use the boat?

Hi all,
Seems we have some jokers amongst the crowd. My unit does the same as the $500.00 dollar device, but will cost me less than a 1/5th of the price. Parts are ordered, including an emergency strobe. Range I estimate at 250-450 feet. The remote will also have the ability to turn on/off two other 12 volt max 10amp devices. I suspect I will have the working prototype ready by this May. Scott.

We are a bunch of jokers but I think some are trying to be diplomatic about your idea. Personally, I don't see the point in what you are doing. I'll explain my PERSONAL view:

You say this device is to be secondary to using a tether (killcord?) so straight away I see it as a redundant complication - more bits to fail. I've suffered killswitch failure at sea - twice - and I wouldn't want two of the things working in tandem.

If you regard it as back up (in case of forgetting to attach a killcord) then I'd say (IMVHO) that a 450 foot range is very dangerous indeed. Google what happens when RIBs and small boats eject the driver - very often they lock into a tight circle and eventually run the person in the water over - often many times. IMO, your device will do nothing to prevent this scenario.

I think he may be planning a 450m range to press a button to switch it off? So you manually intervene rather than it looses contact and switches off.

If its 450m and loss of contact I'm gonna get annoyed when I leave it in the car. Halfway out the harbour the engine dies for apparently no reason. Towed in. Restarts. Halfway out again. Almost exactly the same spot she dies again. Blah blah

Scott, there is a use for a device which alerts people on a vessel that someone has fallen overboard. Generally it is quite different from a rib though. People who sail in watches may well be interested as often only one person is awake and on deck at a time and so if someone goes over the boat can be far away. However consider that those devices should ideally do the following:

- Alert other crew members to the incident audible/visual
- mark the casualty position on the chart plotter
- possibly reduce speed / remove autopilot, if that isn't going to expose the remaining occupants to more risk.
-If single handed possibly activate a distress message (that is probably the hardest bit to achieve)

Preferably the system would be activated automatically (by loss of signal so it fails safe) as you can't assume the casualty is conscious, or capable of pressing a distress button. If you believe this is not true Google cold shock.

There are a few commercial systems around for this sort of thing. Whilst you can build the parts cheaper, you can't robustly test them etc...
