The Nicro fan units keep air moving all the time, even a dead calm. My
Alberg has two, one mounted in the bow one over the lazaette. The bow
unit died this past spring and I can tell you the difference that little
fan made was definetly noticeable by the crop of mildew I got because of
not replacing it immediately.

When you drill through your core, you should saturate the surrounding
edge of the hole with epoxy resin, use a heat gun to thin it out a bit
and drive it in deeper on the edges. Digging it out and putting in putty
just pushes the unsealed edge back out of sight.

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.

Sorry for not being clearer. To treat the edge of a 4" hole in a cored
glass deck, you want both to seal the core and to re-establish a structural
connection between the skins. I'd burrow out the core to a depth of 1/2 and
fill the trough with a putty of epoxy, wood flour and cabosil. For
burrowing the trough i'd try a slotting router bit.

I put 2 dorade boxes on my boat a couple of years ago.
They are great at keeping the cabin fresh in brisk conditions when you
can't crack a hatch. When you have a hard driving rain at anchor the cool
breeze is very welcome.
They don't pass a lot of air in most conditions but they do help. I used
off the shelf teak boxes then cambered them to fit the deck and be level
on top. They also have a vetus mushroom vent that is operable from below
and a SS hoop to keep lines from fouling the cowl. These were a lot of
work but they look good and they work good. I figure whatever you do to
your boat, do the best you can the first time or ya end up doing it over.

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.
