For whatever reason, I seem to be particularly sensitive to mold, having
just had another recurrence of a burst eardrum here at home (clogged
Eustachian tubes, infection follows, pressure builds up and necropsy
finishes it).

I'm a physician so I'm a little confused. Necropsy is a synonym of autopsy
which usually occurs after death. Thus it would seem that your (earthly)
problems are over and worrying about ventilation on the boat is the least of
your concerns ;-)

Necropsy certainly "finishes it".

Hiya...

Seems I have a misremembrance of terminology.

What I'm trying to convey is that I develop a bit of dead skin where there
used to be an eardrum. As this is the analysis/diagnosis of both vets :{))
I went to separated by more than 4 years, I concluded it was chronic. That
it's a product of mold is a presumption of my current home's circumstance,
as very expensively determined by sophisticated air sampling in and around
the premises to have higher than normal concentrations of same...

I think what I meant to say was having necrotic tissue - is that more
appropriate to the discussion of the symptoms? Or, for the physicians here,
what *did* I want to say? :{))

See my other followup, to myself, for the OnT discussion...

Hi, Y'all,

Well, on the recommendation of nearly every list to which I've posed this
question, solar vents are superior in performance and cost, in particular
for water intrusion.

As it happens, we already have one or two (not sure if the other is a fan or
just a vent), and it seems to keep the boat relatively fresh.

With awnings, however, I don't think they'd work. My thought now is to have
a very low draw muffin fan constantly moving air through, perhaps in the
anchor locker, pulling through the entire boat.

The draw's small enough that it could run all the time, particularly with
the electrical system I'm headed for (1300AH, major solar plus KISS
generator) in the Caribbean.

Interesting, I have 4 dorade vents and one solar vent. Only the solar vent
leaks, but only when the wind and rain are just right - just enough that I
need to be carefull what I leave sitting under it.

I had two of the Nicro solar vents on my C&C 36. They lasted about three
years before the plastic deteriorated and started leaking like crazy. This
was the stainless model so I was surprised to the see the plastic below the
stainless cover fall apart so fast. Nicro told me to take a hike when I
asked them about the problem. Solution was to throw them overboard and plug
the hole...then I sold the boat.

I imagine Skip has necrosis in mind.
Pressure which reduces blood flow
with the usual consequence

Brian Whatcott Altus, OK

We took the dorades off Leonidas ten years ago and then used four types
of solar vents. None worked very well. They all leaked badly. In
ideal conditions they provided only small amounts of air, but their
batteries frequently were too low, they do not work in sultry overcast
conditions and then they just stopped working. The makers/agents were
uninterested in problems.

We have gone back to dorades, and if you install them I suggest:
* biggest cowls you can find (sucks in more air),
* rotating cowls so you can orientate them to the wind,
* we face them away from the wind in stronger winds & they then suck
air out of the boat,
* when boat is left in marina we face them in opposite directions to
cope with wind shifts,
* "three legged" rope guards over all cowls,
* insect screens inside the boxes,
* fairly large dorade boxes as they work as water separators, and this
requires space,
* some way of sealing the vent into the boat (eg screw down mushroom
cap). The traditional pair of sox is suboptimal.

Best of luck and fair winds

... Has anyone retrofit
dorades to their boats?

We're looking at long periods on the hook, when we'll be off the
boat all
day (commuting, in the Caribbean) and are looking at mold and mildew

prevention.

For whatever reason, I seem to be particularly sensitive to mold,
having
just had another recurrence of a burst eardrum here at home (clogged

Eustachian tubes, infection follows, pressure builds up and necropsy

finishes it). Thus, making sure we have a free flow of air will be
important.

We'll have full awnings, but don't want to leave the boat open, nor
do we
want to go to bars/grates which would allow leaving the hatches
cracked/open
but (in my, prior security industry-experienced, view) severely
compromising
emergency exit.

Thus the thought of dorades. Two questions about that:

Is it a big deal in our cored deck, or about the same as installing
a winch
or other topside item?

If you've done it, are you happy with the outcome?

I'm thinking in terms of a couple forward, facing forward, and
another
couple aft, facing aft, when we're at anchor, with caps for in and
out when
we're in the Briny (I'd sure hate to dump a bucket of water down on
the new
bedding!!). That, I presume, would allow for a pretty consistent
air flow
through the boat. Finding somewhere to put them which won't screw
up our
deck space any more than is already the case will be the biggest
challenge.

So, experience??

Thanks.

What are, "three legged" rope guards over all cowls"?
