I also considered the gas version so it didnt make a mess of the electrics. But the supplier said if he was on a RIB that caught fire he would just jump off !

So I went for a small 2kg hand held and plan to mount it low down on the outside of the main console. Easy access, removable when stowing the boat.

I also figured if it catches fire Im going to jump off rather than try to put out the flames.
But by the time you've noticed the fire & use your manual ext. It has to have taken hold any way, which could be a lot later than an automatic one would have picked up on an overheating cable. If the fire is in the console, you have to open the hatch to tackle it with your manual ext. Which a; allows oxygen into an otherwise sealed (ish) compartment & b; puts you close to the fire.
Chances are, an automatic extinguisher would have put out the fire before you even knew about it.

That would be a 5 year warranty and unlimited shelf life. No recharge needed and it is a one time use device.

Thanks for the info on them. I couldn't find anything that would handle the marine environment on my little SIB that was small enough. The Quick Draw extinguisher fits the bill and was very reasonably priced here in the USA. Although I do not have to carry a fire extinguisher by law, I will start carrying the Quick Draw fire extinguisher now. Just gotta find a place towards the bow away from my fuel tank and motor to store it. Might attach it to the anchor crate. There is not a lot of safe storage on a boat that gets filled with scuba tanks.

Poly / Pikey Dave - all valid points, which Im still considering and mulling over. (Ive got the 2kg hand held one as a stop gap)

The salesman at the London boat show basically told me the automatic versions would require a lot of heat and flames to go off. So I figured by that time the proximity of the fuel fillers leading to the tanks would likely mean its pretty much time to get off the boat. He seemed pretty open and honest about it and did himself out of a sale, so I didnt doubt what he said.

A smoldering wire would also go un-noticed by me as its inside my console until its too late.

Ideally Im after a gas extinguisher thats automatic and sensitive so it will stop the smoldering wire setting the whole lot off. Not an automatic one that needs naked flames before it goes off.

Has anyone got experience of how sensitive the automatic ones are ?

Excellent - or perhaps I could fit a big plug. When it starts to go up in flames I could just pull the plug and let the sea put it out.

Yup, it will never catch fire with this much water in it:

I think that an auto needs to get up to about 70C before it goes off.

Maybe a smoke detector in the console would be a good idea?
