Comfort Blanket
Instead of cooling the entire cabin how about some sort of "comfort blanket" for sleeping. Sorta like a heating pad, only in reverse. Circulate some cold water through tubes or something much more brilliant than that.

They have used coolant/water through tubes/mats under bedding in hospitals for many years. Have always wondered if could be applied, using a low power consumption curc. pump, either direct or indirect from cooler (hopefully) seawater? Maybe a projest for Sara?

The issue with a cooling blanket or something similar is that a boat has a high humidity atmosphere for the most part. Anything colder than the air is going to get condensation on it.

there has been an apparent break from the old tradition of using canvas as a tool---i wonder why--is most effective and reliable....is it because the marina residents donot like the appearance of cruising boats?? or what isit--isnt simple to make a/c for boats nor is it reliable--keeping simple keeps ye on th ewater ...lol sailing instead of repairing...

Hahhahahaha..... Nice one ZeeHag..... best post I've read for Yonks...

Can some one tell me what the name of the box that the air scoop/funnel/vent
is called?

Do you mean the Dorado Vent....

**daddle** · 26-03-2010, 05:57

Four methods...sailboats can change their position on the face of the earth. Therefore a motivated occupant can simply move to most any climate they desire. Say San Francisco, for example.

Also, as an engineer you'll need to wrestle with this weird amp-hour measurement boaters use (comparable to coulombs I think) rather than the more useful watt-hour.

Thanks boatman61

Now is that the actual name of the vent that looks like an old fashioned
telephone mouth peice or the box that it sits on?

**daddle** · 26-03-2010, 06:33

D-o-r-a-d-e is a different kind of fish than a Dorado. And it's the vent you seek.

**boatman61** · 26-03-2010, 06:38

The "Mouthpeice" is a KOWELL..aka Cowl... the actual Dorado/e is the box it sits on which basiclly has 2 bits of wood or plastic inside, designed to stop any/most water that may get inside the box from entering the boat(Capsize excluded)... this then drains away through holes at the side...
Though someone may know otherwise....

**s/v Jedi** · 26-03-2010, 06:40

The box that the dorade vent is mounted on is called a "water separator" or "dorade box". The boxes that you can buy are often very ugly so many boats have custom build them.

Jedi has 15 dorades but all the water separators are integrated into the deck coamings or other superstructure.

There's plenty of boat ACs out there that work fine. Provided you have lots of AC current to power it. What's needed is a 12-24VDC heat pump type system that uses less than 10Amps...On a boat, the biggest issue is generally the power sources that are needed to run the current assortment of devices that more and more sailors, or their wifes, won't leave home without...

Real sailors use awnings for shade and open hatches/ports for air flow rather than reley on AC. haha. How many on this forum lived before there as such a thing as home AC in any form?? Remember sleeping porches? Good old days?? I'm not too sure about that...

1.Get awnings up. 2.Take off clothes.3.still hot? go for a swim! No engineer needed . No consumption of energy.

Furface · 26-03-2010, 06:46

Cowl and dorado, got it. Thanks boatman61 and s/v jedi.

See Dorade box - Wikipedia, the free encyclopedia for how they work and the history.

The name comes from the name of the yacht (Dorade) that first had these boxes. Dorade & Dorado are both fishes and they might even swap the type of fish meant from one language to another.
Here's the first ever Dorade box aboard the Dorade:

Dorade is an Olin Stephens designed yacht built in 1930. Rod Stephens designed the dorade box. Rod was the brother of Olin and the brothers started S&S with Drake Sparkman.
