Hi, just a thought
What if you rig a circuit to say a bulb or buzzer on the console so it doesnt interfer with the engine but does allert the driver.
I'm not electrically minded but im sure someone will be along soon that could draw a wiring diagram for 'dumies' which i would be interested in seeing as i have pondered this question before....

K&S - it is very easy to do. Get a suitable 12V lamp and mount on the dash. Get a suitable buzzer and wire in series to the lamp. Wire one side of these to the battery. The other is then wired in parallel to each kill cord switch. Then these are wired (preferably via a fuse) to the battery. If you want to get fancy you can add a "mute" switch somewhere to shut the bloody buzzer up.

If you really want a wiring diagram - I will scribble one for you - but as per my comments above I think it is unlikely to ever be needed. Especially since keeping a good look out in all directions you would soon notice if the other half had disappeared.

It sounds like there would be scope for someone to be wearing a kill cord but it not be "live" within your description ("switched out of circuit") that sounds vulnerable to being forgotten about to me.

Given that kill cord switches have a reputation of being unreliable does multiplying the switches not increase the risk of a problem preventing starting?
Thankfully I have never lost anyone overboard, and hope I never do.
The plan was to have the switch on the console with a warning light to show if 'out of circuit'.
Because of the reputation of them being unreliable was another reason for being able to take them 'out of circuit'.

May have a rethink and do a hybrid system with the 2 X double jockeys at the stern and the single behind the helmsmans wired with kill switches to a strobe/sounder on the console. Additionally on the single jockey behind the helmsmans seat fit a engine kill switch for when one of the youngsters is at the helm, in case I go overboard, which is my worst nightmare.

Hi, thanks for the explination Polwart, easy when someone else explains it. Think i could probably manage that.
I'm sure its a bit over the top and will probably never be used but what if .... for the sake of a few quid i think i will fit a system ... having to wear their own kil cords adds to the excitment for the kids

There has been stuff here before on how to link two cords together on a single switch when training. My preference when letting someone inexperienced helm is for me to keep the kill cord. If I go over then it stops if they go over then I am able to go back for them...

I would of thought the multiple kill cord thing would be daft. What if your littleone moves their legs while your at high speed, kicks the kill cord and sends you flying as you dont expect it.

On my old rib if an inexperienced person was at the helm then I had 2 cords on the switch as I was along side them, but on the new rib I will be on a seperate jockey behind them and I dont want the kill switch stretching back from the console.

K&S - I am bored in a hotel on Business so have done you a doodle - not up to JW's standard...

2 versions - the simple version and then a very slightly more complicated version with a single pole double throw switch (2 position) that allows you to turn off the system (or silence it after activated) but provides a warning light (LED) as rickuk3 was suggesting to show that the system is disabled.

Of course you can add more and more features to this to make it more sophisticated - but that is more and more potential faults...

I would suggest if you do this that rather than wire direct to battery as shown it is wired so it is only on when the ignition is on.

Surley, the bulb and sounder would be better in Parallel.
If used in series should the bulb fail then the buzzer would not sound either.
all IMVHO of course
