We visited
our sail maker just before Christmas to talk to him about getting a Code D sail
made for Mareda. I stammered around clumsily, explaining that I wasn't exactly
clear about the technical specifications.
He stopped me immediately.
“Let me
make it simple for you,” he said.
“NOBODY knows what a Code D is, nor a Code 0, nor a Code 5. You just tell me what you want the sail to
do, and I’ll make it.”
This did,
in fact, clear up a lot. Various
technical articles and web sites of the major sail makers all have a different
opinion on what these headsails are supposed to do. In general, a “Code” sail simply means a
headsail on a removable furler. The Code
D is a light-to-medium wind reaching sail that can be used with a large apparent
wind angle from 60° to a full 180° polled out. I suspect that the name “Code D” was invented
by Delta sails, while the generic term for it is a Code 2. But I much prefer my sail maker’s take on
things: forget about what it’s called and focus on what it does.

While smaller than a classic spinnaker, a Code D can
be used with a larger range of wind angles than with either a symmetrical or
asymmetrical spinnaker, and the fact that it is on a removable furler makes it
easy to set and easy to douse by short-handed crews. This is exactly what we are looking for.
Fortunately, our sail maker already has some
experience directly with Sun Odyssey 379s and suggests a sail area of 65 m2. A symmetrical spinnaker for the SO 379 is 99
m2 so we will lose some power, but we’ll gladly trade power for ease
of handling. Because it’s so easy to
use, we’ll put it up earlier and take it down later than with a spinnaker, or
so we’re told by Code D owners.
In the technical articles that compare various
headsail options, the Code D wins over both symmetrical and asymmetrical
spinnakers and even the famous Jimmy Cornell touted Parasailor. If you can read
French, a couple of great articles are:

But this ease of handling comes at a price. To furl
and un-furl correctly, the size, cut, and material of the sail have to be
adapted specifically to your boat. The error
tolerance for the length of the stay is less than 1%. Too short or too long by
more than this and you’ll end up with a mess when you try to furl the
sail. People who buy sails and furler
systems without having a custom fit are usually the same ones who gripe that
furling spinnakers are crap.
The price, however, even with our custom-made sail, is
still cheaper than the spinnaker option from Jeanneau for the SO379. Go figure.
The only downside, then, is that we have to be patient and wait for the
sail maker to make his detailed measurements once the boat is delivered. He says once he has all the numbers he needs,
he can deliver the sail in 15 days. He’ll
also be making a 3rd reef point in the main sail for us, and we’ll
have to rig up a way to fix it to the boom.
It just can’t be any worse than what we had to do on Spray.
In Part 2, I’ll describe the nitty-gritty of the
hardware, equipment, and installation, with pictures from Mareda, sometime in
late May when she's all rigged. Stay Tuned !
