Re: Flying a Symmetrical Like an Asymmetrical

Okay, another question!

Someone suggested that I might consider rigging another halyard for the chute, but my masthead is super-simple. Only has four sheaves: two for the main and two for the jib. Looks exactly like this:

So, there's that stainless D on the forward part of the masthead. Do you think I could attach another block there and hoist the chute from there, or am I just begging to tear half of my masthead away doing that? I've no idea what that loop is there for.

You can safely do that, I thinks it's meant for it

That's exactly what it's for...gets the sail out in front of your forestay so you can gybe it without entanglement.

I've seen this article before and I'm always convinced I'm missing something obvious. It appears that gybing with this setup will result in the downhaul twisting around the furled genoa. Since the lazy sheet has been run outside the forestay/furler, the kite will be gybed on the outside. As a result, the downhaul, which is rigged aft of the genoa, will twist around the furler and I'd imagine this would interfere with the ability to adjust the downhaul. What am I missing?

I agree with you and I don't do it that way.

I don't have a furler but my tack downhaul block is forward of the forestay.

I've just been given a fairly suitably sized symmetrical spinnaker for my boat. I don't have a pole or any hardware for flying a symmetrical right, and I'm rocking a pretty draconian budget, so I'm working on VERY little disposable cash (yeah, yeah, get rid of the boat :P)

Anyway, I whipped up a jury rig last night to fly the symmetrical like an asym, basically tying one clew to a bow cleat, and sheeting the other end. It worked out surprisingly well, and I'm pretty sure my boat's never gone faster. Sure, there was a mess of curl at the luff, but there was a LOT of square footage filled up.

So now, with that successful experiment out of the way, I'm considering rigging this in a *slightly* more legitimate manner, and I was wondering if there is any kind of information about this practice, or if I'm just completely bugnuts. I mean, it seems kind of daft to fly an symmetrical like this, but man, I can't argue with the results.

Any tips? References? Guides?
Glad it worked for you.

But why not just fly it as a symmetrical spi, just without the boom? Even though I have a spi boom with all its paraphernalia, I do this some times to avoid the complexity of the boom. You won't be pointing very high but if you are running or on a broad reach, it will sure speed you up!

Re: Flying a Symmetrical Like an Asymmetrical

I think that the above graphic is from a Sail Magazine article from a few years ago. IMHO the art department got it a little bit wrong in the first graphic. The turning block should be in front of the head stay and not behind. The second graphic shows the lazy sheet going in front of the head stay as it should. If you rigged your boat this way, the spinnaker halyard would chafe against the headstay after gybing and with the halyard wrapped, it would be very difficult in dousing the sail after a run.

I suspect the illustration was simply generic to illustrate the use of the parrel bead collar around the headstay and the adjustable tack height. On our boat we rig the stemhead turning block from the lazy anchor roller, ahead of the stay. Note, however, that, unlike an asymmetric it would be very difficult to effect a gybe with a full symmetric. Doable, but very difficult.

Re: Flying a Symmetrical Like an Asymmetrical

If I might, he has a hank on jib, the TAN might get trashed sliding up and down a bare forestay...

an EASIER solution (and cheaper)... would be to get s block forward and run a tackline back to the cockpit... as he gets closer to DDW, he can ease the tack, blowing it forward some, and sheet the heck out of it as he gets closer abeam.

Something like this would work (just put it low on the pulpit, but forward https://www.catalinadirect.com/index...roduct_ID=1329 )... You aren't planning on running this in 20+ true anyway.

Oh and someone converted the symmetrical to asym on my 22... they actually put a hank about 10 inches up from one clew along with a tackline lead back to the cockpit... worked well, from almost beam to deep broad reach... Faster than the 155 racing genoa up until almost beam. This wasn't my idea, it was the prior owners, I just USED it!

it worked OK...
