Help with Nacra 6.0na with Spinnaker

I have purchased a 94 Nacra 6.0na. My experience is with an older 5.8 so I think I can rig the boat, but the 6.0 has a tramp launched spinnaker. I have never rigged a spin and need help. Any pictures or other advice would be appreciated. The boat has a spin pole and jib roll furler.

Thanks

Mike,



Like many others, I have some experience with tramp launching a spin from a boat like yours. I have #111, '94 N6.0na. Now I have a retrofitted snuffer and I-20 spin.



Launching, first I put out the tack, then the head, then trim it. all going almost dead down wind.



Retrieving, make sure the halyard is not tangled, throw it off the stern and let it drag in the water, this keeps tension on the chjute as it comes down, so it doesn't end up under the boat.

collapse the chute at the foot by releasing the tack line, the release the halyard and pull it down onto the tramp. then stow it in the bag and clean up the lines.



I won't go into block placement and what I've done to route my spin sheet around the boards, and then behind the jib sheets. It takes three blocks on each side to do it, but iot really reduces line fouling. Your clew block depends on your foot length and cut of your chute. Didn't it already have a place for them for your set-up?



Good luck, let me/us know how it's going.

Picture is worth a thousand words...I will take some pictures when I am rigged in the next week or so. What size spinnaker are you running? Please describe the hardware on the pole and boat and I will try to figure out if it is similar to my set up.

I have an identically rigged Prindle 19, with the obvious exception of the bridle foil. I can take pictures next time it's rigged if you like, or try to answer specific questions. Good luck

Thanks for the help.

I just got the boat a few days ago, and will not be able to rig it till Saturday. There are two different size spins with the boat. I have not measured them yet. The spin pole has a bail at the end, I assume for attaching a block. There are two small sheet metal screws in the end of the pole? The main traveler was modified at the ends to accept blocks. There are two hounds on the mast, I guess for the different size spins. The most puzzling piece is two cam cleats on top of the rear traveler about a foot from the end. They are positioned for cleating a line coming from aft of the rear beam? On the front beam there are also two cleats, roll furler, spin guy? I have not determined where the halyard cleats yet. There are two large cam cleats on slides. They fit in the jib tracks. They could be for cross sheeting the jib and/or cleating the spin.

Thanks again for the help.

I would bet that the cleats on the rear beam are for a rudder control system. That was popular on the 5.8's and some 6.0's did it as well. I would also guess that the cleats on the slides are for the jib inhaul/outhaul system. Do you know if the spinnaker system was designed with a single halyard/tack line or if they were separate lines? If it's a single halyard/tack line, there is probably a set of back-to-back bullet blocks (Harken #114 - http://www.harkenstore.com/uniface.urd/scpdinw1.ShowProd?B4RPMEB9Y8V4ZO) in the setup somewhere.

Tim,

The cleats on the slides are Harken 150s. The jib inhaul/outhaul stock jam cleats are still in place. Is the spin sheet usually cleated while sailing? The spin equipment does have the back to back blocks you mentioned. How does this system work?

Thanks

Most cats flying chutes don't have cleats unless they are doing long distance racing and they set up something on the windward side (cleat on the shroud, etc.) for temporary cleating. The single halyard/tack line is hard to explain with words, but I'll give it a shot.



The tack line starts at the end of the spin pole, comes back through one end of the back-to-back blocks, goes back to the end of the pole through a bullet block. It then comes back to the tramp where it hooks on to the tack of the spin. You should not ever have to pull this line.



The spin halyard starts at the head of the spinnaker, goes through the block on the spinnaker mast tang, down to the base of the mast, through a block on the spin pole, out through the empty end of the back-to-back block, and then back to a cleat on the tramp.



When you pull the spin halyard it also pulls in the tack line so that the tack of the spin is pulled out. Hopefully this helps.

Read this document on how to make a spin setup it has some drawings that might help.



go to folder at



http://www.geocities.com/kustzeilen/Genaker/



There you'll find a word97 document with vector drawings and a decribtion of some 10 pages.



There are also some pictures in the same folder ; one showing the back to back harken blocks.



It also described the way a spi is rigged to some extend



Hope this helps.

Thanks for the help guys. At least I have an idea of how it works now. I will try it Saturday and let all know how it goes.

Thanks

The spinnaker worked great this weekend although the air was light. The combination halyard and tack line is a neat trick. My only problem was the tack line and the spin sheet got into the jib sheets while the spin was down.



We furled the jib, then launched the spin over the jib sheets. I noticed in some pictures today that some people leave the jib out while flying the spinnaker. In this case would they launch the spin over or under the jib sheets?



Also if anyone can describe the setup for the furler/bridle/jib connection it would be appreciated. I got it to work, but I don't think that is how it was designed.



Thanks

I don't have a 6.0, but just added a spin to my H-18. We've found so far that if you are going to furl the jib, it works best to set the spinnaker THEN furl the jib. When dousing, unfurl the jib FIRST, then douse the spinnaker. This helps us put the spinnaker away such that it doesn't interfere with jib, and keeps us sailing with all the needed sail area at all times while racing. If we did the jib first and last instead of last and first, we ended up sailing a lot under main only, but we're still learning!

The chute launches and douses UNDER the jib sheets. If you have barberhaulers to the main beam, go in front of them too, or take them off for spinnaker work. Your jib will never need to be out that far with the chute up.

The length of the tack line/halyard should be just enough to securely stow the chute while there are just a few inches (or a foot or two) of line beyond the halyard cleat. Between snugging up the halyard after the spin bag is zipped, and stowing the spin sheet, umm, somewhere, you shouldn't have a lot of trouble. I stuff it in the sleeve that covers the transverse wire for my jib blocks, but I have a P-19, and I don't remember if the 6.O comes with one or not.



No idea on the bridle/furler/jib (got all but the bridle foil, and I'm confused enough about mine!)
