I would like to submit a response to the "Humming noise from boom" string, but am not sure how. Is this the proper avenue or do I need to go ? My response is:
FYI, we were moored one evening during a strong breeze. When we went below, we heard a strong vibration/throbbing sound that sounded just like there was a large power boat bearing down on us. After several trips on deck to find no traffic, we finally discovered we had the mainsheet so tight that the resonant frequency of the sheet and boom were matching the wind frequency. We eased up slightly on the mainsheet and it went away. Much better peace of mind.

The Promariner chargers are crap!!! I'm on charger #8 in two years. The only
reason I still have one is that they send me a new one each time free. When
that quits, I'm going with the Xantrex.

On our 2002, I've found that sometimes twisting the black plastic
grille covering the 'buzzer' right or left (thus tightening or
loosening it) will temporarily fix it. This 'buzzer' is really a very
small speaker (piezo element aka 'coil' driving a plastic diaphragm
aka 'speaker cone'), thus I think that sometimes the grille expands/
contracts with temperature changes and prevents the diaphragm from
vibrating. A test to confirm this would be to substitute an external
buzzer for the original; I've not done that yet. While I don't ignore
the gauges and buzzers, I tend to rely more on my ears (engine
noises), and nose (engine smells) as monitors.

Let's not forget to tell Bob that his bilge pump is hardwired to the
battery. Very important; done so that the bilge pump will function
regardless of what position you leave the main battery switch in.
Yes, you'd have to leave the main battery switch on either battery one
or two, if you wanted to run anything (fridge) else. Yes, the
breakers (red buttons) are very hard to move. However, even if you'd
managed to 'disengage' or 'open' either or both, that wouldn't kill
your batteries. The windlass doesn't run unless you're at the bow
stepping on the footswitch, and the purpose of the main breaker is to
disconnect the rest of the boat or 'load' from the batteries. The
charger would still charge the batteries. Chargers (like many
electronic widgets) do simply up and die ('worked fine until it
quit'), some more than others. Your charger may be in the 'more'
category, brands below.

It could be the alarm itself. I had to replace mine earlier this year.
I think you can find the part number if you search the archives.
Or the oil pressure sensor on the engine could be bad. (The reason you
hear the alarm before you start the engine is because there is no oil
pressure.) Check to see if the oil pressure warning light comes on. If
it does, then the problem is probably the alarm. If not, then it could
be the sensor, or the wiring to the sensor, or a bad connection somewhere.
BTW, replacing the alarm was very easy.

Yes, the stock one is a 24v part. I replaced mine with 12v and now it
is VERY LOUD!

Guys,
If the alarm doesn't sound. quickly look at the alarm indicator light.
If its lit when the alarm isn't sounding, then the circuit back to the
engine low oil pressure switch is OK.

You may have already done this but it is not uncommon for the plugs on the shore power cord to short out. Check to make sure that you have power on the boat end of the cord.

Subject: [C320-list] Battery Charger Problems
Arrived at the boat this weekend to discover both batteries dead;
completely drained. Shore power was hooked up correctly and the breaker-switch
was
in the on position for the battery charger. The only auxillary units
left on were the bilge pump and refrigeration. The boat had been sitting
unused for several weeks because of the weather. Mold was starting to appear
in the fridge, so it must have been out for a while. There was not even
enough power in the batteries to get the marine radio to function.
Borrowed the marina's battery charger and trickle charged the batteries for
several hours. Created enough battery power to turn on the engine.
Alternator seems to be working ok.
Question is: do chargers just up and die like that? Our is a Promatic
30-3. Doesn't seem to be any switch on the unit itself. When the
dockside power cord is connected to the boat, and the breaker switch to the
charger is turned on, the needle on the charger unit doesn't move at all. And
yes, there is power coming from the dock-side outlet through the power
cable.
Before I order a new unit, I thought I would check in with you experts.
Any suggestions would be helpful. This is our first full season with the
boat and still learning.
If there is one factor that may or may not have to do with this problem is
that several weeks ago I was fiddling with the two knobs at the battery
panel where you can switch from battery 1, to 2, All, or off. Off to the
right are two red knobs. I was trying to learn how to turn on the anchor
windlass (the lower of the two red pull-knobs). The top knob appears to be
the main breaker. I couldn't get either knob to move and didn't want to
bust them by pulling/pushing too hard. Never did figure out how to work the
windlass. Other than that, I haven't done anything out of the ordinary.
With the batteries both juiced up again, all seems to be working well. I
left the boat for the week, but did not reattach the shore power cable.
Left the battery switch to Battery 1. The only auxiliary item left on is
the bilge pump. The fridge is now turned off.
Thanks!

There should be a manufacturers name on it somewhere. Does it use 2 lines or a continuous furling line?

I don't know how to answer that. What options are there?

FWIW I have standard rigging and have always had a hum from the standing
rigging when the wind is up and the boat is in the "groove". I have walked
all over the boat and cannot find anything vibrating. After awhile I just
ignored it and after 10 years it's still there.

Humming, whistling and other kinds of noises are very common when the
wind blows across the slot of an inmast furling system at just the right
angle. If you search the web you can find lots of anecdotes. The usual
solution is to get a sailmaker to make up some kind of an antiwhistle
strip that you hoist up the back of the mast to interrupt the airflow.
