This could usher in a more robust safety system from manufacturers like an inhibitting RFID chip or something in the loop that should be around your leg, but it could easily be cut off (the chip not the leg)

It would be funny if it was wet, the spark would certainly wake him up!

Give him a length of electric fence cord. That would keep his ticker lively.

Is there a hint of what happened in the sentence:

"Stop the engine before transferring the kill cord to another driver."


The suggestions of an RFID device don't work. Its OK if you have it in your pocket, but would you cary a spare so you can retrieve the person? The spare will still be in the boat so the RFID wont know its missing. People will leave the RFID aboard for next time then forget to put it in their pocket etc.

Low tech works. Yes the cord needs a decent breaking strain. Cord length is probably rarely considered.

The only way I can see a reminder working would be if the switch maybe needed to be tripped before restarting the engine. So you stop at a jetty for lunch. When you restart the engine either it wont restart till you remove and reinsert the kill cord which should remind you to attach the cord, OR it produces some form of warning (light, alarm, speed limitter) if you haven't....

That is an absolutely excellent idea. It makes you have to positively think about it.. Would stop twits with Mercurys who leave the switch permanently on with no cord, and all other make of kill cord too. Only the real idiots could "forget" to clip it on to themselves if they had to clip & unclip each time. Would stop those with cable ties around the kill switch, etc etc. Having to actually touch it in order to un clip and reclip is the best reminder of all.

Only issue is that it would undoubtedly require a move to an "electronic" style switch as opposed to the currect "discrete electronic" system, if you get what I mean. But it would still be low tech enough to be reliable

I've been giving this some thought and I'd like to float (pardon the pun) an idea for comments/opinions.

My first thought was for something along the lines of a 'dead man's brake' and so I got to thinking about those sort of applications. The train analogy, where the driver has to maintain pressure on the throttle (as I understand it) is not an option, as discussed earlier with the idea of a sprung loaded throttle. But a far more common arrangement may be viable.

If you have an electric lawnmower then I suspect you'll already be familiar with it.

In the case of my Bosch, before the motor will start (on a push button), you have to pull back the bar that runs parallel to the handle. As soon as you let go of that pull bar the motor stops.

My idea would be to have a secondary 'ring' behind the steering wheel that has to be pulled back against the wheel before the engine will start. As soon as that ring is released, the engine would stop. And to stop anyone from simply tie-wrapping the ring to the wheel, the 'trip' action of the ring being drawn back would have to take place within a defined time (say 3 seconds) before the starter circuit is activated.

I don't know about anyone else, but I can't see why the helm would need to let go of the wheel (and hence the ring) under any normal conditions.

If this is a crap idea then I'm happy to be shot down. If not, then how do I patent it?

You can't patent it as you've just made it public. :-)

I know, but would it work? If so, consider it my gift to the boating world

Disagree entirely. I often potter along at idle in flat calm sea looking at the scenery or animals/birds. I often take both hands off the wheel as I eat a butty or something. Turn 180 to talk to someone for a second.

Same applies for spring loaded throttle, not fit for all purposes. Trolling whilst fishing for example.

I maintain. EDUCATION EDUCATION and give people common sense.

Nice idea but it'd become tiring on the hands after a while and you'd have to keep a grip round all parts of the wheel. You'd also be relying on a rotating contact round the wheel continuing to work.

I have a far simpler idea.

Run a version of an 'alternator field disconnect' on the ignition swich, so you can ONLY stop the motor (ie, stop the alternator putting out power) by pulling off the kill cord.
Turning the ignition switch to 'off' won't stop the motor so the kill cord has to be removed and refitted to restart the motor. Once the motor has stopped, the ignition key will work as normal.


Simple and easy to fit and to retrofit (would simply mean a replacement ignition switch).


It's very hard to leave a killcord dangling if you have to remove it to stop the motor.
