Sounds too good to be true!

From the brief description I believe that the generator described is a
DC generator which in turn drives an inverter to produce AC.
Essentially the same system as the new Honda. If so it should solve a
lot of problems.

Sure you have.

We have a nice quiet engine room diesel running at 1800 RPM, with a
sound shield and water lift muffler. It's almost inaudible from off
the boat except for the chuffing of the exhaust water. We try to have
it off by 11:00PM and no one has ever complained. If they do I'll
invite them over for frozen pizza and Hagen Daz ice cream.

That's an interesting product but you can get almost as much power
using a big alternator and an inverter. Add a large battery bank of
400 to 800 Amp Hours and you have a great deal of flexibility. It's
important to get the alternator mounted correctly: Solid mount,
properly aligned, and the right belt(s).

If I were planning on putting a generator in a boat I'd "ping" Larry
as he recently described a new model Honda that apparently is a DC

is quite and efficient.

Unfortunately that is not a marine generator that can be installed
below decks, nor it is a diesel.
Technically untrue. You can create an isolated compartment and vent
overboard.

I don't think Glenn's goal can be achieved on a small boat without silly
compromises. Frex, I could create the compartment, sound proof it, etc,
but then he'd lose his fuel tank, etc.

It all depends on breeze. If you on anchor, it's ok. If you are tied up
at the dock, especially in Aug and Sep, then it's tough, but then you
have shore power.

The only time I've been badly distressed in FL during summer is being
anchored in the inland near a spit of land which was full of flying
insects. I wanted to shut the boat up due to the insects -- not the heat.

I suggest you TRY it first and then decide. I never had any temperature
issues away from land aside from flyng insects.

Pie in the sky. It'll never happen. Portable generator users don't
wanna listen to a bunch of portables grinding away all night long
any more than the rest of us. When they turn off their noise they
expect it to be quiet. That's how these people are. It's me, myself
and I. That's their mentality.

Built-in generators with water lift mufflers are an acceptable
alternative as far as noise goes. If there's any wind at all they
can't even be heard because their exhaust sounds pretty much like
waves lapping on a hull. But, most of them are diesel. And we all
know diesel stinks. I sure don't wanna be breathing diesel fumes
all night long. Even if I can't hear the exhaust, I can smell the
fumes. So what diesel boats need to do is anchor downwind of
EVERYBODY! Unfortunately you rarely see it. They know that
downwind from everybody exposes them to assholes who anchor upwind
of everybody and run generators.

The only civilized alternative is anchored boats should all contain
considerate people who care about their fellow boater and who all
agree that once the sun sets any and all generators are to be
turned off. (Ever hear of storage batteries? Try fans instead of
air conditioning!) This includes those obnoxious wind generators,
too. The noise they make is particularly bothersome. How has it
come about that a few selfish people are ruining cruising for all
concerned?
