Really they should manufacture a dual killcord, one plastic fitting for the switch but two curly leads. That way helm 2 can attach before helm 1 detaches if swapping helms.

That would not help my berthing scenario where I am a long way from the helm getting fenders out of lockers, but it's generally calmer seas and shallow enough to anchor in that instance, so a dead engine is only an inconvenience rather than a danger.

You can already diy this solution (as the rya recommend when training children) but it doesn't help do what Simon wants which is have the kc permanently attached to life jackets to prevent forgetfulness. it would be theoretically possible to have two kill switches wired in so you can connect one before removing the other one but it introduces other risks.

I like that idea, and it's a modification that I'd seriously consider.

Unfortunately I can see it being counterproductive if it became mainstream as anyone less inclined to use a kill cord wouldn't even need to have the annoying bit of red curly stuff dangling in the breeze!

If you really don't want a kc dangling you only need a pair of scissors...

I teach PB2 on a rib with dual kill switches. Pulling either will kill the engine. That setup would work perfectly in the swapping helms scenario, but I have only ever seen it on ribs used for teaching (and the Honda Youth Rib Challenge boats but in those the 2nd kill switch is forward of the console for the person crouched in the bow area).

Some remote throttles come with a spare kill switch plastic bit (no curly lead) stored in a purpose built slot

Don't you want it wired so either switch (rather than both) keeps the engine running? i.e. Helm 1 is on one switch with engine running, then Helm 2 comes along plugs into second switch, and the first helm pulls chord and walks away. Engine stays running all the time, unless both chords are tugged. Only one is chord is usually connected at a time apart from during changeover, when it requires both people to be thrown to stop engine.

The one I use needs both to be plugged in for the engine to run. Means I can kill the power at any time by just moving my leg or yanking the cord, or if I get ejected from the boat the trainees cannot come back and run me over

Which is why I believe that the engine should be stopped every time with the kill cord. I cannot see any reason why this should not be SOP taught by the RYA. It is not a fault tolerant system and so MUST be tested every time.

Someone suggested that some engines should not be stopped with the kill cord. This is not true. Disconnecting the battery on a modern engine could be bad. Using the kill cord on a properly installed engine will never be bad and is equivalent to turning off the key.

Understood Chris, and that is what you need for a training boat. Instead I was thinking of Simon B's situation where they want to change helm safely, while also allowing them to keep the engine running.
