thread related to ventilation

[luis nin estevez]

Hi,
I'm trying to find threads about ventilation in little cruisers, but through "Search" I only see a blank page as answer.
Can you help me.
Thank you,
Rds

Luis..... I used 12 volt computer fans and a dedicated solat panel to drive them. My boat is always dry and fresh smelling and at the same temperature as the outside air. The fans are about three inches square and rated about 24 cubic feet per minite with a .8 watt draw.

Edited to add: They have been is service now for six years but not in salt air, this far up the bay we are in fresh water.

Luis,

Welcome aboard! The SEARCH feature is broken for Building/Repair but works in the other areas of the Forum.

For those who don't know Luis, he is building John Wlesford's SWAGGIE in Uruguay. If all goes well, his boat will be the first SWAGGIE launched.

Here is another post from paladin (Chuck)...

for what it's worth....and my two cents ain't much.......I would go with the Dudley Dix Cape henry 21......it would be within the purview of a dedicated person to build in less than a year, would have more room inside, and with NO dorades but use the Nicro solar ventilators and replace the NiCad battery with an equal size (physically) NiMH and double the "out of sunlight" operational time and set them all to SUCK out the air instead of bringing it in...there's enough air leaks in a boat already....forget the windows or ports...use a large lexan panel on the coach roof and maybe a 1/2 in lexan port at eye level so that you can see outside...the horizon...when sailing solo and you go below for a snack.....a single burner sea swing stove is all you need....a cheeep potty and holding tank will be required.....but a bucket will work when you are out of folks sight....keep it simple...build the darn thing and GO!

There are others in various sections here. Use nicro for your search word. Chuck will be along soon and answer your questions.

Cheers!

Hello Luis....
The little Nicro solar vents are wonderful devices. If you cannot obtain them for whatever reason at your location, I would be happy to make some drawings so that you can fabricate a version of your own using Solar panels and charging circuit.
Basically you must construct a small dorade type box, without the cowl ventilator. From the underside of the cabin run a flexible tube from the bottom of the box, behind a bulkhead, and into the bilge. With small exhaust fans on constant exhaust the air is drawn from the bilge and out of the boat. Fresh air is drawn into the main area of the boat, down into the bilge and out, keeping the boat fresh and dry.
if you need some sketches, use the e-mail function to send me your snail mail address. it may take me a few days to respond

My experience with Nicro vents isn't so favourable. I installed one in Grantala. It was the most expensive one available locally at over $300 ($US225) with another $60 for the chrome cover.

The on-off switch failed in a relatively short time - and would not have been used more than 20 times. I've still got it - disassembled in a plastic bag, waiting for me to get around to melting the great wad of hot glue that is holding the 2 cent switch in.

I don't like feeling ripped off - and that's how I feel with my Nicro vent.

:mad:

Ian...
the ones i use do not have an on/off switch and have been working for about 14 years.....

My computer fans cost about ten bucks each and the Seimens solar panel was about 120 USD. I mounted the fans under Nicro water trap vents.

I 'd like to install Nicro solar vents ; however, I don't know which one and how many I will need for my SWAGGIE. Any thoughts?

I looked at your site, very nice, big, little boat. When I planned my ventilation I wanted five air changes per hour in the cabin and choose fans to meet that need.
Loose bolts in your hat-- in the states we say loose screw somewhere. :D

Luis,

I have had mostly good results with Nicro vents although I do not use the rechargeable battery units since I think (I know) they would be less reliable. They have always worked very good in keeping mold and smells away in a humid coastal climate. One problem is that two units were snatched overboard by jib sheets. A cover that fastens the unit securely to the deck is necessary to prevent that on a sailboat.

I now use a wind powered Nicro vent to exhaust the fuel tank space in a powerboat and it seems to work fine. The little DC pancake fans for cooling electronic equipment powered by solar panel that heve been mentioned might be better in that they don't need to be mounted in a sunny spot. Mounting them in a Dorade or other protected deck vent would probably work well.
