My E-O snuffer on my N6.0, has caught many a wave in rough conditions wihtout the chute up. So...

I lashed it to the underside and in front of the foil, and the spin pole, as a 'guk' style snuffer. 2/1/03 was my first on the water test and it went well! The bag goes under the tramp some, I may try it over the tramp, but the dern 4way jib crap is up there.

Anyway, no more catching waves offshore like a big spatula!

As I"ve heard though, you can't seem to snuff it at as hot an angle to the wind, as in you have to go more off the wind.

Anyone else try something like this?

I'm working on the same sort of setup but my experiementation has been slowed by some serious hull repairs!

I have a crazy dream that if you route the bag under the trampoline and put a turning block on the rear beam, you can continue your dousing line through the turning block, on top and forward on the trampoline, up the mast, to the spin block, and back down to the head of the spinnaker - your dousing line now doubles as your halyard. You get rid of one line and ALL that halyard slack on the tramp with the chute up.

In addition to this setup, if you put the halyard/dousing line through the pole to a 1:2 setup on the spin tack line, out of the pole and THEN up the mast as a halyard = one line for a spin set and take down - and with relatively no slack on the trampoline. I had a dream of this one night and I am pretty sure I've seen it since on a few other cats. Anyone know how well this works?

Most of the 18HT's using snuffers have rigged a continous spin halyard/belly (retrieval) line. The line passes through a block on the rear beam and has just enough slack for the crew to get long pulls during the hoist. The system works very well, I know a lot of the I20 guys have a similar setup. As for rigging the tack line as well, Brian Lambert and Jamie Livingston used that setup at Tradewinds and it appeared to work very well, even in the breeze.

Jake,

That's exactly how I have mine now, with a seperate Tack line though. I"ll work on a set-up like you state in the future with the tack line.

I just use the E-O snuffer head, took it out of the end of the pole, and lashed it to the front of the foil and the pole, works great!

My turning block for the halyard is under the tramp, back at the rear beam. I may put it thru the tramp with a grommet, but for now, the halyard/retreival line (1line) is the same as I used for the end of the pole snuffer, and it still works great under the tramp.

I do have the PC, I-20 chute, that works great too.

Todd,
How did you "lash" it to the pole and the foil?
Does the Hoop portion actually hang slightly under and off to the side of the pole?
Are you using the same hoop that you had?

Eric, Rob,

Yes, for simplicities sake, I just used the same CF hoop of the e-o snuffer and lashed it to the underside and in front of the bridle foil along the port side of the pole, and to the pole.

Eric, people such as John Tomko, when discussing this, suggested I 'glass' a lip to rivet or bolt to the pole. I simply got out my scrap line bag, and found several pieces of suitable line (some old spectra, etc.) and lashed! With a little trail and error, I managed to get a very snug fit, easier then farbricating.

Rob, I can take some pics in a few weeks when I use it again, but you can imagine how it looks pretty easy. The e-o hoop from the end lashed to the port side of the pole, and in front of the bridle foil of my N6.0. The same bag extends about 18" under the tramp, and the retrieval/halyard line used, (the same one as before) now goes to a block near the center and at the rear beam. Reteival portion under the tramp, halyard portion over the top to my 'spin lock' then up the mast.

With this set-up, I re-used my tack line cleat for the spin, as a 'tack line' is now also needed.

Still a little tweaking, but it works well.

I only did this because in some extreme conditions without the chute out of the bag(snuffer), I've caught the hoop on some big waves like a big spatula, and ripped it off. Mainly because it sits so much lower on the N6.0.

People also say it has advantages, such as less weight out front, and less windage.

I only did it b/c of it sitting so low on my N6.0, that it caught some waves, and without the chute up to support the pole from going downward, it wasn't pretty!

We rig the H*ll out of it to keep it from going up much, but nothing supports it from bending down without the chute up, and that e-o snuffer, with a bag full of spin., is one big spatula!

I saw the first "EO Snuffed 6.0 with Smyth spinnaker” Pitchpole harder than any boat I have ever seen. After thinking about we realized the "spatula" was the cause. The boat basically stuffed in the "spatula" and pivoted around it. It was wild looking.

Todd,

Just curious if you'd ever considered putting longer stays on the foil to raise it up a bit (like some of the NE N6.0 sailors have done)?

How much of the "spatula effect" is caused by the bag itself?
Would it work much better if you had a bag with the first 1 or 2 feet from the snuffer made fron an open mesh or net?
I know the Tiger people had many problems with the standard tapered Hobie bag.
Many of them have since bought Elliot/Pattison non-tapered bags.
Apparently the spi jams into the tapered bag so tight that the water drains very slowly.
What about a completely net bag? Maybe long enough to store the spi or most of it, under the tramp?

Just guessing here.

Hey Sam -

My 4.3 has a full-length net bag. It drains well, is a little stretchy, and lets some breeze through. Looks kinda like football jersey material.

You going to Spring Fever? 17?

Hi John,
Of course. The Spring Fever Regatta is way too much fun to miss.
If weather is nice this year and everbody shows up, maybe we can finish drinking that wall of beer cases this time.
Unless I get real lucky and find a Marstrom A-Class real cheap, I will be dragging my Hobie 17 down there.
Did you get a Taipan yet?

See ya,
Sam

Kevin,

I use the KISS principle. So I have stock length stays, made out of turnbuckles-similiar to waht you see on diamond wires. This negates having to change that expensive piece of rigging-they're good for life! Raising the foil would of course shorten my luff length, and would necesitate more mast rake to compensate, of raise the head hound more. Nwither of which I want to do right now. With the new wet-up, the lower pole is no problem. If it buries, it has very little compared to the spatula.

Sam,

I think the resistence is simply cause by the diameter of the CF hoop, and the spin in the bag, thus not not having any luff tension on the end of the pole. Nothing 'stays' it from going downward when the chute is snuffed. Now it's all up at the foil, with a separate tack line. How many times have you seen a 6.0 bury the foil? The mesh bag would only help to a small extent, when the spin is in it. Put your hand out the window in a moving car, and with your fingers apart, there's still alot of resistence. The people with the 'guk' style snuffers (like mine now) have alot of advantages IMO.

Todd,

I agree on the KISS. I was thinking, however, about the boats I see with chutes and lots of rake. Often I see guys rigged with extenders on the forestay to accomodate the rake. I was thinking that the longer stays on the bridle would eliminate the need for the extender.

I agree. a good way to get that rake in, still may have to shorten shrowds a bit.
