Idlewild 04/23/06: Punching into head seas near Yap

I was tempted to respond to something that was posted the other day,  but
Ben's comments prompt me to do so now.

Someone wrote to the effect that Jim Leishman had engineered or  othewise
discovered the usefulness of the day tank in tracking fuel consumption.  This
idea, of course, is almost 100 years old.

Now, we have yet another situation where someone solved the ventilation
problem with the boxes we now refer to as Dorades, as they were first used on
that small boat. As well-thought-out and equipped as my boat is, the Vetus vents
with "Dorades" are a joke when any green water comes aboard, and will soon
be replaced with the real thing. The drains on these boxes will be about one
square inch in size, and plentiful (12 on a 20 x 10" x 10" box, constructed
from  5/4 teak). The Dorades on my Westsail 43 are made this way, and they allow
water mist-free ventilation in all conditions short of a storm. Ben may yet
have  an opportunity to fit similar boxes. The ones I see on boats today have
drains  which are much too small, and too few. Style has overcome
practicality, and it  seems that the trawler world still has has much to learn from that
of  sail.

T'was I who wrote that! (response to a question on how
fuel consumption on the N40 ATW was monitored). I
didn't ascribe anything magical to a day tank (in
fact, didn't even call it a day tank), just that
Leishman had calibrated a very small tank in
half-ounce increments, all plumbed with Aero Equippe
(sp?) hoses and stainless steel valves, a bullet proof
solution for crossing a ~2500 nm stretch of ocean with
~900 gallons of diesel. The idea may be a hundred
years old, but I have not seen it deployed so
elegantly in a small production boat. (as a matter of
fact, I don't recall seeing a similar setup on any
other boat in the N40 class). This is now available on
new Nordhavns.

The Dorades on my Westsail 43 allow
mist-free ventilation in all
conditions short of a storm. Style
has overcome practicality, and it
seems that the trawler world still
has has much to learn from that
of  sail.

Given Idlewild's schedule and arduous route, my guess
is they need ventilation in storm conditions too.
These guys seem pretty hardy and awfully resourceful,
chances are they are well ahead of the development
curve - sail or otherwise. I'd be hard pressed to call
Idlewild's design a nod to "style over practicality."
