Re: [Electric Boats] Re: Propane generators

 

Ie, for every three months of living aboard and cruising, usage was (the gasoline equivalent of) approximately one 20# standard propane cylinder -- available at Home Depot etc etc (http://uscarb.websitetoolbox.com/post/how-much-propane-will-i-use-compared-to-gasoline-5337749).  Living permanently tied up at the 79th St Boat Basin in the Big Apple is kind of a special situation.  No Home Depots near there!

Re system leaks: very true.  For my barby, I always turn off the valve at the tank (which should be on deck and with the valve protected from unintentional impact) and allow all fuel in the line to burn off.

I've worked with H2 which has the special benefit of rising rapidly when released -- rather than sinking and pooling -- due to its super-light molecular weight.  But even if/when H2 becomes available, I'd stick with C3H8: much bigger molecule and thus easier/cheaper to contain, much less energetic and with lower vapor pressure, and higher CV thanks to its carbon content.  And already available at HDs.

 As long as you are near a good location for refilling your propane tank it should work. But, if you plan to cruise propane can be a problem. When I was living a board in New York City back in the late 1990's there was only one place in the entire city that I could get the tank filled and I would have to leave it overnight.  This was pre 9/11. Wonder how much questioning I'd go through these days from the authorities as to why I was carrying around a propane tank in the city. :)  Personally, for me gas is the most  widely available fuel around. Easily available at docks or at local gas stations. The good thing about EP and the gas sipping generators like the Honda 2000i is I carry a lot less fuel on board than when I had diesel.   I went through less than ten gallons in last years six month season while living aboard and cruising.

Propane is a heavier than air fuel and presents a fire/explosion hazard just like gasoline. A leak in a gasoline system will gravity feed fuel loss to the level of the leak. A propane system stores fuel under pressure and will force all the fuel out in the event of a leak. Both systems have to be maintained and treated with caution.
