Have any of you used a gennaker with the tack on a spinnaker pole for down wind angles that normally result in the main blanketing the gennaker?
When I was 20 (30 omg years ago) my fathers 27ft boat had an asymmetric spinnaker and I remember mounting it like a spinnaker and it worked.
I was just thinking that if you are in DDW conditions that you could add a guy line to the gennaker tack for the pole, then ease off the normal tack line which would in affect become the poles downhaul. To gybe you would remove the pole and gybe like a normal gennaker.
I'm thinking of supplementing my Code 1 with a deep shouldered genny for downwind angles, something like in this video and was thinking why couldn't it be used all the way to 180 :-)

All the time. Said maker recommend this one a symmetric too! As you get more of the sail showing for better down wind boat speeds.
I leave the tack line attached. Pole hooked to tack. The have lines available es side for pulling the pole. And i prefer a continuous line for the view to the spin. I also do outside jibes, a line to es side works best. I might have a picture, then again, probably not.
When closer to reach angles, the pole is not as useful. But very much so in the 145-180 dead down wind area.

I'm a little surprised that I've never seen this suggested either on a sailmakers site or in one of the magazine "tips" articles.

Never really, as I sail mostly alone and flying a spinaker on a pole on our own is just hard work.
There are however some tricks to make down wind sailing with a gennaker a little better. I.e. a barber hauler on the sheet, which brings the "shoulders" of the gennaker more to the middle of the boat. This gives you at least 10 degrees more down wind. This can be tweeked by playing with the footline and halyard too. Also the fact I have a little bowsprit helps a lot with this trimming.

Yeah, using the pole is a pain in the ass. Normally I goosewing bothe my genoa & code 1 poleless and if it's colapsing to much I gybe one of the sails and go on a reach. I think I've only used the pole because I was in the mood to test it. The big problem I can see myself having will be that I will be flying the sail and then decide I want to go DDW with the pole but the guy line is not mounted to the tack and the tack is flying a meter in front of forestay
In a couple of weeks I will probably go to a boat show on the West coast and speak to sailmakers about options/prices and perhaps see what the say about the pole out of curiosity
I use a barber hauler on my code 1 for more down wind angles.
The sail in the video seemed to be flown quite deep and I could imagine that a barber hauler changing the sheet angle might allow the tack to fly a little further to the windward side

Not sure who,h show you are going to go to. It try to find Chuck from Ullman San Diego/Seattle, he is the on that explained it to me. Assuming your west coast reference,e is N America. I've been playing with it and it works well to get a bit better down wind angles. Works like the tweakers talked about, but one uses a pole to get the luff to the other side of the main.

Hoppy, Go HERE and there are some quick how to pointers on using a pole with an asymmetric spin. Marty Good to see sail makers don't have any issues with doing it Can an Asymmetrical Spinnaker be used with a pole?
Yes, you can fly the Asymmetrical Spinnaker the same way you fly a Symmetrical. It is more efficient at the same angle and that turns into speed. The only difference is when you jibe an Asymmetrical Spinnaker you have to turn the spinnaker inside out. This requires rigging slightly different and a different technique.When I get a more down wind gennaker, i will make sure I have a line suitable for a guy. I already have a mount midships for a barber hauler which I can add a block for the guy which i should be able to lead directly to the winch. One guy will be enough  |

I regularly transfer my asymmetric tack from the bow prodder to a spinnaker pole and back again. We have a very oversize pole that when attached to the mast and the front end is lowered it comes in line with the asymmetric tack. About 4.5 metres from the mast to the prodder end and the pole is 5 metres long. I have a snapshackle at the tack for transferring the asymmetric from the furler to the pole. We put the asymmetric back on the furler and gybe it inside.
For short square runs I sometimes fly the asymmetric to windward by running a little oversquare. Unfortunately the rules do not let you put the tack on the prodder and the clew on the spinnaker pole but I do intend to try it for cruising.
Regards
David

David,
I have a couple of times done the pole as mentioned. Works fairly well. A lot a wing on wing with a Genoa/jib on a whisker pole.
What I have found either way, at least my old whisker pole was too small, not strong enough to handle the strength of the asymmetric. One needs a spin pole, or maybe a size up whisker.

One of the things I do to keep the gennaker full is to attach a snatch block to the end of the boom and route the gennaker's clew sheet through it, when at least 135° off the wind. We wanted to try deploying the whisker pole with the gennaker, but never had "the right moment" last season to try that. We did rather well directly downwind with the genoa deployed to one side with the whisker pole and the gennaker to the other!
