I'm sure the women of america and their physicians will have a difficult
time deciding from one of your cheap rube goldberg substitutions for
standard mammography gear, and the non-mammographic research and devices
being developed at the reputable Dartmouth School of Medicine.

Probably similar to what Cardinal Bellarmine told Galileo.

Halyards against masts(not shrouds), a noise I quickly stop hearing
although it drives others crazy. Most of the time you can minimize it
simply by pulling the halyard tight. I always forget to do this.

make much outside noise. Some of those owners think the Honda's
should be outlawed at anchorages.

What's with Honda's being the bad guy? Why mention Honda? These
generators are made by a variety of manufacturers.

I would say Honda generators aren't the problem, it's the construction
site type generators that are the problem. You know the ones.

I use an inverter, four golf cart batteries for the house bank, and have
a large alternator on the main engine. I'm good for 4 days on the hook,
no charging, and the ice cream is hard enough to bend a spoon. I use
electricity exactly the same at anchor that I use it at the dock.

Occasionally, with an hour or two of charging, I have a full tank of hot
water for showers, and topped off batteries.

A separate generator is not necessary as far as I can see. Not even
desirable.

Big, water cooled internal generators that run all day and night are
very annoying to me. Shut the damn thing off and shut off some lights.

Everyone who thinks they have to run their generator to make coffee is
the problem.

That's the one usually mentioned, because they are the most common,
because from most accounts they are the best. Wasn't knocking Honda.
That's what I'd get.

Mind you, I know about this only from reading, and the Honda's are
sometimes specifically mentioned.

I'd have a similar setup on a bigger boat with an internal diesel.
And also have solar and perhaps wind.
But my boating plans will likely end with OB power, and my post about
OB's with better charging output was in that vein. That way I could
easily do without a dedicated generator.

water for showers, and topped off batteries.

I agree "not desirable." The "not necessary" is harder to pin down.
I don't know where you boat/sail, but reading journals of Caribbean
and Florida cruisers (Florida is where I'll be) there are plenty of
complaints about droning generators running almost constantly,
including all night.
The heat can be brutal, and though my wife is hardy, it may be
necessary to provide a respite with A/C. Not that I don't appreciate
a cooling off myself, but with her no respite from sweating could be a
deal killer.
My intent there is to use the smallest home unit and cool only a berth
area. How I would do that is another subject.
But having limited A/C was the reason behind my initial post.
Duty cycle would be light, but the amps might be impossible to
replace practically with a small OB alternator.

Big, water cooled internal generators that run all day and night are
very annoying to me. Shut the damn thing off and shut off some lights.

Yet those running them often complain about the gas generators on
decks, and say their gensets are almost dead silent.

Everyone who thinks they have to run their generator to make coffee is
the problem.

Add TV's, microwaves, walk-in reefers, etc.
Not anything I want to do. But I appreciate a good night's sleep
at less than 90 degrees.
BTW, if you search a bit for Hondas and cruisers, you might be
surprised to find how many small sailboats with alts attached to
diesels use the Honda's often enough because they don't want to run
the inboard, for one reason or another.
So though you and I may agree about keeping electric power consumption
low, others disagree.
I wonder how the Texans and other gulf cruisers handle the heat when
they cruise if they don't have A/C.
For a short trip sleeping on deck is a possibility, but I think when
you get to week you want to dive into a cool berth when nightime
temps stay high, below decks is hotter, and it's raining.
I'm willing to torture myself a bit - but I'm a man.
My wife has a different psychological makeup.
Thank God for that!

I was thinking about you being down there in Texas and wonder how you
handle exactly that.

Well I don't drink coffee so there wouldn't be a coffee maker.

But dude - gotta have air conditioning. :)

Don't leave home without it.

Or mount the AC and run the generator - like everybody else would do - if they
were out here...

That's a good question and I can partially answer it - A/C. My son
has been using the Grady which has A/C in the step down. From what
he's told me, it gets hot there even at night when the temps are in
the high 70s. No cross ventilation in the cuddy. I can speak to the
cuddy being a little uncomfortable when I took it down to Charleston a
couple of months ago.

http://www.gradywhite.com/336/ - click on the cabin tour.

And we've got a Honda EU3000i on the boat to run the A/C.

I'll give you a personal evaluation when I go down in August. :)

you get to week you want to dive into a cool berth when nightime

Not me. My physiological heat control circled the bowl in SEA and only
got worse when I lived down South for a few years in MS and LA. I hate
the cold and I hate the heat.

I'm only comfortable between the temperatures of 68 and 80 degrees
which means I probably should move to Hawaii. :)
