Enclosed cabin powerboat - kill cord usage debate

Umm, switch off the ignition perhaps..?
Then turn it further to the spring loaded stop position! This isn't rocket science. :D

:D
No, it isn't "rocket science". Your suggestion, switch the ignition off. For a reason I do not understand, boat diesel engines do not work like car diesels, if I switch the ignition off in my wife's diesel car , the engine stops...................but a poster on a boating forum who didn't seem to know that merely switching the ignition to off on some diesel powered boats would not stop a boat diesel engine running ? Diesel car driving guests on board would not know that either.

You're making a meal of this. It was a throw-away comment to point out you COULD stop an engine if someone had collapsed over the throttle.

Because in a car it is safety related and in most cases when you switch the ignition off it stops the engine, in a marine environment you could switch an engine/s off accidentally and losing your engine/s could cause fatalities and it comes down to risk management and which has the lowest risk in its own environment.

But, how many faulty diesel engined cars have a problem with the engine and begin revving after being switched off because they are sucking up sump oil and running on it. If this happens in a car you can dip the clutch or put an auto into neutral and apply the brakes, boats are not fitted with Ferodo and in most cases losing engines causes a greater risk.
 
To differentiate between an open power boat and a cruiser.
An open power boat can be “thrown”, manouvered, around such that the driver can be ejected. 1, because of the smaller lesser weight. 2 because it is open.
A cruiser being heavier and larger cannot be manouvered in the same fashion.
eg my 3m rib with 15hp outboard in a sudden full helm change whilst planing would leave be at least 5m away.
Whereas in the 40’ flybridge cruiser, suddenly being steered full lock, I could still stand up and drink my tea.
Or to be ejected from the saloon I would have to climb the steps, open a door, step over a rail and jump.
Then there are all the degrees between.

On life jackets I use 2 phrases. Wear it unless it is safe not to, and useless unless worn.
On kill cords. The kill cord is fitted BEFORE the hand even touches the gear/throttle lever. To encourage this I teach that the kill cord is physically handed to the next person on a changeover or if removed, it is wrapped around the throttle lever as a reminder to fit it

Thanks for the information, with no sarcasm or snide comments. Very useful.
