Has there been any talk on a new spinnaker pole length?
Anyone flown the new spinnaker with anything other than the class pole?

Yes I we have used the class pole and the new longer one, I don't see any great advantage with the longer pole in fact it helps looping the sheet around the bow, not good.

I would have toghth it gives a big advantage as you can have the kite flying higher, special in light winds. It would also seem to me that it is easier sailing half wind (wind coming from the side. sorry do not know the right phrase in English)

beam or reach, yes I agree more extension of the pole would gather more wind/power.

Used 2.5metre pole all last season on Ullswater. Also we set the pole mast loop thingy about 300mm lower as the foot of the sail is naturally lower. Got to be careful when recovering as ericdon says about releasing the guy to early. Just take pole of mast pull towards you a bit and then drop guy as late as poss, dead easy !!

The biggest advantage of the longer pole is that it opens the slot with the kite and main.
The problem with the sheet dropping over the bow happens with the shorter pole as well. I only take the sheet off the pole once the pole is on the boom.

if you put a class pole against the longer proposed pole you will see not a great deal of differance. Moving the pole loop on the mast did nothing for us, as for great advantages I can't honestly say it had any, we still seemed to go faster down wind than most boats at Ullswater. I would have said all boats at Ullswater but, I don't like to blow that trumpet.

The proof was at Carsington at the last blast, Saturday was certainly a blast, we had some great runs down wind with the new pole and a bent mast. It prooves even the old boats can still achieve the boat speed of new ones.

We must have built up such a big lead upwind that the extra speed you had downwind wasn't sufficient !!
Agree about old and new

A longer pole should theoreticaly give an advantage over the shorter one at most angles; as Cuillin said - it opens the slot between the main and the kite stopping stalling and making it easier to fly and allowing a greater mass of air over the front of the jib and main. There is a point where having a longer pole will be detramental because the sails will stop interacting and there will not be a slot effect, but this will be consederably longer than any crew will be willing to try and use without giving the helmasexual at the back a lot of abuse!
How much of an advantage it will give is another question compleatly and I suspect the only way to find out is to consistantly race one against the other over a season.
The problem with dropping the guy over the bow is a definatly a problem with the curent size of pole and most people wate till the kite is back in the shute before removing the guy to avoid the problem (Incidently, this also helps to stop the kite from comming up twisted on the next hoist too!)

Thats strange I can't remeber ever been so familiar with youre transom, it was usually just a flash as we overtook.

all thie theory on the new pole length is interesting but remeber we are only tlking about 6" here, as for slots between kite and main, yes you have a point. But the slot between jib and main is more important especially up wind in a blow, therefore if that slot is good then speed upwind gains you the advantage, so the slot for the kite is less important downwind as you have already got ahead upwind.

six inches can be quite a difference.....

six inches, hmm depending how good the crew is at setting kite and jib, I very much doubt its criticalty down wind apposed to upwind for advantage.
