There are 12v electric sheets that work even better than electric blankets.

The sheet heats the mattress and the blankets on the bed , so when you crawl in the bed is warm!

Even more delightful is that portion of the bed you do not occupy is also warm!

Cold feet? Slide them over a foot to a nice warm area.

These are made as 12V bunk warmers or 120V for larger double beds.


Thanks! This should save diesel from being squandered in the old Washington Stove Works cast iron beast on cold nights...probably more efficient to heat the bed and turn down the stove

"Now, the Honda buzzing away on the deck is a different story. We keep hearing how they're so quiet, just isn't so. You can hear the unmistakable drone of a portable gas generator from clear across the anchorage. It seems owners always pick sunset to crank them up."

No truer words have been spoken on the generator debate. Bottom line, it doesn't matter if the boat is power or sail, its a question of what the generator is and how its set up. I have been next to inboard generators that were whisper quite - the lower the revs the quieter they are. Diesel tends to be better than gas - the gas ones tend to be higher revving. Of course the muffler set up has a lot to do with it.

I'll echo the sentiments on the "Honda's" - they are torture.

Most probably don't follow "Gone With the Wynns" video blog, but if you have enough money to throw at a problem as they evidently do, you can have air conditioning without a generator, but your lithium battery bank will be large:

Running Generators at Night

I'm currently negotiating for a 2006 Mainship 34 that is equipped with Rolls Surrette batteries. I'm told that they will last several hours under load, but have yet to have the opportunity to test this. Maybe one could operate AC over-night without running a noisy genny?

That they are Rolls Surrette, or Optimas, or Acme is irrelevant. It's a basic math problem. A/C uses a given amount of energy in a given amount of time to do a given amount of work. If the battery bank stores enough energy to meet that demand, it will work. If it does not have enough energy, it matters not who made them, it won't work. Y'can't get 10 pounds out of a 5 pound sack.

The rest of the story regarding running AC off of batteries is that you then have to recharge them. While this may be less of a problem while underway as you're producing power with the alternator, it means a lot of generator time or 2 or 3 boats worth of solar panels. Understand that running the AC off the generator, is more efficient than recharging the batteries with a generator and then converting stored power into 120 VAC (both charging batteries and converting with an inverter aren't 100% efficient).

We put a curtain or blanket over the passageway tween the main salon and the fwd berthing cabin. Turn off (shut) the aft heater outlet (air) and the amount of fuel consumed is dramatically reduced.
Most of the heat loss is through the windows in the main salon.

Re: noisy heaters:

The Espar & Wabasto Heaters *are* indeed noisy. (They Sound like small jet engines.)

The Wallas heaters on the other hand are truly silent and literally cannot be heard more than a foot away from the exhaust outlet.

Something to consider if you want to keep your remote silent anchorage quiet.

I believe that's what the broker was inferring, that one could run the AC on a hot night and pull up anchor in the morning. The port engine is equipped with a much larger alternator which apparently charges the Rolls mush faster. I guess time will tell.

not here

before we sold our 26-year stinkpot (36 years old when sold) i found myself trotting along behind buses in new england winters just to enjoy the aroma.
the genset could not be heard from 30 feet away but we only used it "after hours" in emergencies..............
my few sailing adventures had me twiddling my thumbs WAY too much !

My wife has MS and needs to stay cool. We run the generator to power the air conditioner before we put the boat in the water and don't shut it down until she's back on the trailer. That was for 8 days straight when we were on Lake Powell.

Strange how we can go for days, even weeks at a time without using ours living aboard, on the hook.
Solar panels, marvelous things.

I saw that. I was asking why he thought it was strange that he can go a couple of days using solar.

I don't think its strange.
I think its strange that the poster thinks a larger vessel can't exist without a genset as a daily use item
