Is There a Natural Gas Powered Boat In Our Future?

If someone had asked me that question a year ago, I would have said:
"Nonsense, can't possibly happen." Now I'm a little less sure of
that.

Some interesting things have been going on. The supply of natural
gas in the US and Canada has dramatically increased as a result of
improved drilling and exploration technology. We now have more
natural gas than we can readily use or transport, and as a result, at
least in the short term, prices for natural gas have decreased. As
an example, the historic price multiple between a barrel of oil and a
thousand cubic feet of natural gas has been approximately 10 to 1.
It is now at 40 to 1, a huge reduction. This has resulted in a number
of efforts to leverage natural gas as a transportation fuel, i.e.,
trucks, trains, ships, taxi fleets, busses, etc.

Obviously a lot of new infrastructure needs to be built to provide for
compression, transportation and end user filling stations. A lot of
work has already been done in the area of diesel to natural gas
conversion engines. Once a few more of these pieces come together,
natural gas as a transportation fuel will become much more common than
it is now.

In the meanwhile there are some interesting investment opportunities.
