[Electric Boats] Re: Digest Number 2338

 


I was a designer of explosion proof and marine electrical products. you do not want any gas fumes in the bilge or below decks.!!! It takes very little gas to form an explosive atmosphere in an enclosed space. Gas Powered boats come with instructions to run the blowers (coast guard and fire rated) before using anything that could create a spark (even flipping a switch) after fueling or if you even suspect a gas leak. That would include spilled gas from moving a generator. that is why there are so many regs about instalation, use and storage of gas and gas engines aboard boats.
I once had a rental house on the chagrin river in ohio a few hundred feet from a gas dock and one morning while sipping my coffee I watched a power boat back off the dock and blow up when they tried to start the engine. One injured, one dead. I have been a bit cautious of gas ever since.

In our istalation we paid a bit more we are goeng to use portable diesel generator for a bit safer instalation.

So in addition to it not being designed for an enclosed space installation it could be an active danger to the boat. These are light enough that I would see about an above deck shelter for it that is very! well ventilated and easy to access.

If I remember right one cup of gas evaporated into fumes and mixed with air is the equivalent of greater than 10 times its weight in TNT for explosive power.
