Steve:
Advice, that from my experience in these situations, I would agree
with. If the bolt won't turn, anything less than a perfect fit will
begin the 'stripping process' which will ultimately make the job more
difficult.
David, I have tried this 'home made penetration concoction' with
success......by volume, half and half of power steering fluid and
acetone......and make sure if you try this, it gets on the parts you
want unseized and not on other parts, like hoses, belts, etc. I used
an 'eye dropper' which I found very controllable and exact.....almost no
spillage. I loosen the seized bolts on my mixing elbow and exhaust
flange with this concoction before I got into trouble with , maybe a
broken bolt head.

I would NOT try to use an open end wrench of any kind to loosen a bolt
that is really stuck. There is too high a probability that you will
just round off the head and make your task even more difficult. Use
some kind of closed wrench, either the box end of a combination
wrench, or a socket, preferably a six point. From your description it
sounds like a socket is out of the question, which is too bad. I would
not try to use any kind of one size fits all or adjustable for
breaking it loose either. I have never yet seen one that will reliably
transmit torque as good as a solid lump of metal.
Once the bolt is broke free there are many options. I like the box end
wrenches that have the ratchet built in, in situations when a socket
wrench cannot be used. They are almost as good as combination wrenches
for tight fitting situations and the ratchet makes them a lot more
convenient to use.

I was at the boat yesterday and tried to take the heat exchanger
off the engine (Universal M4-30) so I could refurbish the seals
and make sure it is clean
(http://www.pbase.com/mainecruising/heat_exchanger). One bolt
came off easily but the one on the starboard side is a challenge.
I cannot get a socket on it because something from the engine or
transmission is partially blocking frontal access. I found my
wrench selection on board is less than adequate and I need to
upgrade. I tried with a short 1/2" open end wrench and was able
to get it on, but could not budge the bolt. I left it sprayed
with penetrant hoping that will loosen it.
I looked at other wrench types to see what would be useful in
this situation and came upon this ratcheting wrench I had not seen
before:

It looks like something useful to have on the boat as the clamping
action should work on both metric and SAE, it is stainless and it
ratchets. Has anyone tried something like this?
The other type I am considering is the flex head ratcheting wrenches:
