A snuffer system will save you about 12 seconds on the hoist and douse and greatly reduces the pucker factor on the douse if it's really windy. It's still reasonable to carry the spinnaker in a bag on the trampoline for distance sailing - but around the cans, it will cost you some significant time to launch from the deck.
A self tacker too!? Geeesh, you really care for this crew person don't you? <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

I would suggest talking to Rick Bliss at New England Catamarans. www.new-england-catamarans.com He was the leader of the whole 6.0 fleet charge in New England several years ago. The New England 6.0 fleet at it's peak had a local sailor make up some sweet carbon snuffer heads just like the old end pole heads the I-20s came with but without the angle. There might be some around still. Rick also sold a carbon pole out of a place in Boston that went with the head. We used the Skip Elliot snuffer bags. I think that whole set up came out to around a grand. You could probably get a cheaper aluminum pole but keep in mind that the 6.0 has a much bigger spinnaker than the I-20, F-18 and etc. If your boat came with the New England style spinnaker or similar (around 350sq. feet) then you just need to have patches added. If it came with the Worrell style (around 450sq. feet) spinnaker it may be a bit big to snuff. I was going to try adding patches to mine but never got around to it. I did however use the New England Style chute with snuffer and it worked great and I was able to hold my own with I-20s downwind and even pass them in lighter stuff. I have 2 pictures of my snuffer set up in this album.As far as the self tacking jib, it's nothing I ever considered because the 6.0 jib is what really gives the boat it's power and really makes it an awesome ride on a reach. It would be convienent but you'd have to invest in a much smaller jib and lose lots of power. It would definitley be easier on your crew. One thing I would look at is the picture of my jib sheet system. It greatly improves the friendliness of the boat without the crosswire if your boat still has the stock set up. -Todd | | | Re: NACRA 6.0 Spinaker

Posts: 1,459 Annapolis,MD | Ok, what I'm about to say might come off as blasphemy to the accepted notion of how a 6.0 should be rigged, but so be it, here goes...
I believe that the accepted approach to the 6.0 is wrong - that you keep the huge jib and add a large spinnaker. I believe what should be done to this boat is give it a good square top main, alter the jib to sheet to the front crossbeam, and run a flatter more modern kite like that on the Nacra-20. I have yet to try this, but for my experience base on this I have raced my 6.0 with stock sailplan, and with very nice Smyth sails (square top main, even bigger jib). The other 6.0 in our Fleet has used similar sails to the Smyth sails with the NE style spin on a snuffer rig.
The big jib on the 6.0 is nice for reaching, but I think the overlap with the main compromises things upwind, and the wire system is a bear. The tramp loops are a nice way to eliminate this, but I believe that leaves something to be desired as well. Get the jib trim wrong on a big overlapping jib and see how slow you can go on a fast boat..
But if the chute being used is capable of sailing at higher angles like the N-20 spins, the need for the big butt jib goes away and the boat has a better useable range under spinnaker. The more modern shaped flat top main can help recover lost power on close reaches. The only real downside I can see to this is in real light air stuff, but honestly I'm not convinced it will be that much.
If I end up keeping my 6.0 I'll be trying some of these things. Maybe I'll see what happens when the N-20 boards are used as well...

Posts: 12,310 South Carolina | I talked to someone (I can't remember who, but it was someone whose opinion I valued) who wanted to take a N20 rig and put it on a 6.0 chassis - convinced that the hulls of the 6.0 are superior to the N20 I think in non-planing conditions, the 6.0 hulls are definitely superior. They're also more prone to bite you if you push to hard.

Posts: 6,049 Sebring, Florida. | I wonder it that is do-able. Are the distances the same, between the mast step, bow tangs, daggerboards, etc? Will it work? I have thought about putting the F18 sails and spin. on a 5.5 without the bridle foil. I don't know if it would be ballanced corectly though.

Posts: 606 League City, TX | I purchased a used 6.0 that came with a spinaker that has a deck launch system. I have only used it a few times and it seems a bit of a chore for the crew. I am wondering if it would be worth the money to go to a snuffer system, and also to a self tacking jib. I am in my 60's and only do recreational sailing on weekends, and a few short distance races a year. Miami to Key Largo and maybe one other. Any thoughts on which snuffer system would work best. Thanks You should contact Todd Bouton (send him a PM at the TCDYC site.) He has a Nacra 6.0NA with an I-20 spin and home made snuffer system that is both economical, easy to build and effective. It uses corrugated plastic pipe, roof fittings and zip ties. When he first unveiled it we rolled around lauging and proclaiming it would never work. After a couple of succesful trial sets and take downs on the beach we had to eat our words. I went out on the maiden test voyage as crew and can testify that the kite goes up and down just fine with his system. He runs the snuffer tube and pole between the foil and the bridles (below the foils it catches too much water in the rough stuff). Self tackers are great for novice crews. With a resonably sized spinnaker on the boat (e.g. I-20) I don't think you will miss the big jib too much. Perhaps an I-20 jib and self tacker kit could be made to work. It's important to get the hoist height on the jib correct to get a reasonable sheeting angle. Good luck with your modifications - they will all be supported by the UBCCU (United Beach Cat Crew Union). Chris. | | | Re: NACRA 6.0 Spinaker

A couple of notes, not necessarily meant to poke holes just observations.
Switching from a large to a smaller spin needs to be paired up with different techniques - the smaller kite will need hotter angles to get going, using big kite techniques might not get the most out of the N-20 spin. The sheeting angles may not have been right as well as the luff.
The NE 6.0 and variants use the stock main and jib. Again, I would move to a more modern main cut to compliment the smaller kite and jib.
The 6.0 is still a fast boat, I guess I believe with proper rig development you wouldn't need to manhandle as much.
A number of years ago in the NE-100 I crewed on a Tornado that was going through the transition to the new rig. We had the original pin head main, single trap, but self-tacking jib and spinnaker. I remember coming into the Bay at the end of day one coming upon a 6.0 under spin that was barely under control with the big sail. We sailed right by it with less sail area and far less drama, not even flying a hull. Got me to thinking about it.
But in the end you may be right, maybe the 6.0 needs more ummph. But maybe not...
On the other hand if taking some of the edge off makes it a more enjoyable boat to sail, maybe that's ultimately better even if it results in a slower rating. In the end I still can't bring myself to part with my 6.0 even though I'm a N-20 convert! | | | Re: NACRA 6.0 Spinaker

Posts: 1,459 Annapolis,MD | That's right, I remember you there as well! The 6.0 chute didn't seem as big as the Worrell chutes, but you're right that was pre-NE 6.0, so it could have been a biggee. I have a pic I took from a waterproof throw-away camara, I'll have to dig it out. I do remember when it was real light the 6.0s just motored away from us when there was no spin involved. Day 2 was gawd-awful painful... Pics of that race are on the WRCRA site, but for some reason the link to the larger pic of the 6.0 picture doesn't work.
Is your 6.0 on the East or West side of the Bay? Any idea if the owner might interested in joining on some of the reindeer games in Galesville or on the Bay in general? We've got two 6.0s active in the Fleet, one with the Smyth sails, one with RacerX sails (similar to the Smyth in dimension) with spin, and I'm sure they'd love a new friend to square off with! Could you PM contact info to me? Always hunting new blood... | | | Re: NACRA 6.0 Spinaker

Posts: 887 Crofton, MD | Is the 6.0 guy at Podickory Point YC?? that is right near the bridge... I have spent two or three hours with him on the tele. Girlfriend is driving his decision on club and location. Also, he thinks that part of the bay is easier to get to than G'ville. I've invited him to the Invasion and the awards party; I'll forward you his contact info. He has talked with Roger and I directed him to You both, Keith and Todd and even Mark. My hope is that he will realize g'ville is closer time wise then combine that with other boats to race he may be converted after spending his summer in traffic getting to his boat. I'll forward you his contact info. I also plan to have him crew for me on a Tuesday night, just not the first one. 6.0 spinny stuff. We had an earlier generation of worrell spin, it was big, but not the monster some refer to. By my calcs. it was around 425sf. We were learning the technique of spin handling on cats, so I don't really know it potential. However, the RacerX spin we had built was somewhere in the 380ish range and was/is fast. We frustrated a couple of our N20 guys by being faster and lower than them, when I had really good crew. It was not based on the NE spec, it maximized luff length, shortened foot and was flat but not N20 flat. Also the leach was shorter to allow rear beam sheeting and better visibility under it. It is snuffable. I have threatened to put the RacerX 6.0 spin on the N20. that has gone over as Todd might say a tird in the punch bowl.
