Dorade retrofit
 

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.

I'd look very hard at the Nicro Day&Night solar vents.
They do work, especially if there's wind or sun.
They don't ship water in normal circumstances, but can, in extremis, be replaced with a plug.
They're cleaner and are less likely to snag sheets
They have batteries to keep 'em going all night. A good thing.
Installation is simpler . Burrowing out some core and backfilling with putty is a good idea. Inside trim rings are available.

Dorades are great. They look "right" when done well, and they do the job
(with some limitations). The downside is that a good installation is
onerous, and an effective dorade (i.e., in the 5" range) is expensive,
especially if you go with bronze or chromed bronze.

First I would not just drill a hole and fit a dorade. You will be most
pleased if you mount a dorade "box" of some sort (either wood or
purpose-built plastic) that retards water ingress, and then mount the vent
itself on the box. This is not simple since most surfaces on a sailing boat
are curved to some degree.

I think you will be happier (and have more leisure time) with the Nicro
solar units mentioned in another post. Get the big ones and start drilling.

Good luck and good sailing.

You can;t really just mount a dorade without a dorade box. Otherwise
you have no protection againt almost any moisture like rain, etc. A solar-
powered vent is a good choice.

Hiya, Skip,

Count me as another vote for solar vents. Unless you just gotta have
the aesthetics of dorades, there's no contest, IMO.

Frank

I think we have some confusion of terminology.

'Dorade' is a successful ocean racer designed by Olin Stephens.

'cowl ventilator ' is a bent funnel which is mounted on a deckplate and encourages air below.

'Dorade box' is a water-trap box on which a cowl ventilator is mounted. Keeps most water from going below. First seen on Dorade.

'dorade vent' is the combination of a cowl ventilator and a Dorade box.

I hope this helps.

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.

Good luck,

Jonathan

I think everybody knows what the disussion is about. Now provide us with
the pronounciation of "dorade"? Is it DOR-ADD or DOR-ADE?

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.
