we're aiming to add better light to moderate 120 to 60 degrees apparent capabilites filling the gap between my quite heavy 150% genoa
(terrific upwind and moderate to heavy foresail) and symmetrical spi (terrific DDW to about 120 degrees apparent).
The challenge with non-foil Code 0 sails
is gaining sufficient low stretch luff tension. I'm planning on a 2:1 halyard
of about 10mm V-100. This means the sprit and rigging
likewise has to be substantial enough to take the loads.
Dave, make sure that your stays, and stay attachments are up to the job! I have been through 4 or 5 versions, before I finally got what i needed. The forces using a Code 0 are incredible! For your size boat I would go minimum
½" wires for the stays. I would reccomend that you have some 316L brackets made that attach on the outside of the bows, down low, that go across the bow inboard to attach the stays. This spreads the force to both sides of the hulls.
You need to be aware of the large force that works nearly horizontally on the forebeam. If your forebeam doesn't have a beam in the middle going back to the bridgedeck, you can either add one, or else, do like I did.
I made an "horisontal dolphin/seagull striker" that is fitted on the aft side of the forebeam just under the tramp. It is made of 12 mm wire. The "height" is around 10-12", and it attaches to a couple of hooks that attach to the outer edges of the forebeam.
Before adding this I was getting nearly an inch of deflection in the beam!
My code 0 is 70 m2 and made of kevlar, the halyard is Dyneema
, 12 mm. No purchase
on the halyard that stays on the selftailer.
Once the whole bowsprit was working OK, i managed to bend the top 2m of my mast
and had to replace the mast
. The Code 0 is a masthead version. I was inattentive, on a reach of around 80 degr. relative, sailing round an island. As the wind
went forward, I just trimmed the sail, the boat accelerated to 12-13 knots, it was great, until I noticed the luff was sagging. Looking up, the top of the mast had bent about ½ a metre!
That's how you burn 10 grand!!! NOT SMART.
I use a German made Bartels endless furler in a size IV, that will handle up to 100 m2 Code 0, and larger asymmetrics/screachers.
The list prices are: Endless furler size IV (180 mm diameter) 570 Euros
Swivel to match: 290 Euros
In total around 1300 US$
I didn't check if they have a US dealer, but their site is here: frameenglisch
The prices are on page 1 of their price list.
It has worked well for me for more than 6 years. Just ease the halyard a few inches before rolling the sail up.
My new mast has an extra set of spreaders to support the top.
