I generally teach people to "test" the kill switch after launching the boat and getting it into a safe place, then use the key for the rest of the day.

I guess it's just a matter of if the switches are wired in parallel or series, as to how they work. Should be a simple wiring modification.

I recently heard a suggestion from an instructor for whom I have tremendous respect that we should be teaching "RYA Approved" methods, matched to a bit of common sense. He suggested that on day one of the PB2, every changeover is done by the book. On day 2, we take the view of "let's be adults about this - the RYA method is the safest, but as long as one person has hold of the killcord at all times, we can do a changeover with the engine running."

What are your thoughts on this?

It depends what your intention is! And, this is one of the risks with it - if people aren't quite sure they misunderstand and misuse, as well as just another electronic component to fail. All the more likely if people are using different boats with different configs.

On a pb2 course I teach turning the engine off BEFORE removing the killcord. This means restarting the rib on the key maybe 50 or 60 times each day, basically every time we switch helms. That fine by me, that's what the battery is for, and it drums the process into the trainees so it becomes second nature for when they get their own rib

There are some exceptions. When we are using a pull start tiller steer (20hp) for part of the course some of the less strong trainees struggle to restart it. If that happens I say "I'll hold the killcord while you change over, but it should really be turned off". If I make the person that struggles restart the engine every time they get embarrassed about it, which then affects their learning of the current exercise. But on the electric start its engine off every time.

Just ordered our lot of cords, the Suzuki design looks like it can be "hot" swapped, I'll be up at the boat to do some brake work so we can run it up on the muffs to test the theory.

To be brutally honest though, if our motor doesnt start after a kill cord activation we need to know this and we shouldn't be relying on it staying going all day if its that fussy. So no problem in changing our behaviour to switch off the engine to change drivers/helms.

The Milly accident has made our club think about this and move to a more safe safety culture so its good.

I think the idea of that is so that once the helm has gone for a swim the crew can restart & go fetch....... (read on)

....but based on the people I am usually out with there are maybe 2 of the regulars that I would fully trust to come back to me & not knock me sensless with the bow were I bobbing in the brine......




As has been said dozens of times before - we are trying to legislate for human nature, which by it's very being is self destructive - we forget, we get complacent, and if things get so complicated to be foolproof a proportion of us will try to circumvent it for an easy life.



As someone who (as alluded to earlier) has a museum piece of an engine that is statistically less likely to restart, I still pull the cord off safely clear of the launch place. That's why I have an Aux.

And yes, I sail single handed most of the time so I take my cord off & leave the merc spluttering on the transom to tie up, but realistically if I go over the side in that situation I'm way more likely to die of either getting crushed between boat & pier or being knocked unconcious against pier or boat & drowning than being minced by the engine with it's mechanical neutral lock.


Never forget that every situation is differnet and should be appraised on it's own merits & risks. Wide brush policies are rarely the best option.
