Anybody know of a good website that shows how to gybe a spinnaker using twin lines. Or can anyone offer some advice. forgot to say the pole is fixed so i cant end for end it.
I have found Selden a very good reference point. Here is a link to the Adobe document on their web-site. The document offers several different methods for gybing.
It should be possible to just fly the kite without pole as you go through the jibe, keep the boat on a dead run until foredeck has clipped in the new guy. You need a good trimmer with guy in one hand and sheet in the other, ideally both running to winches on the coach roof. You use the same technique for a float drop when you need to be able to tack emediately on dropping the kite, this way you can get the pole ouit of the way whilst still flying the kite.
Best to see what works for you in the set up you have with regard to winches etc.
Agree with Tiga Wave, you need a good trimmer, and the helmsman needs to keep the boat dead downwind to allow the trimmer any chance of keeping it flying, and the Gorilla to dip the pole through and attach it to the new guy.
We do it as TigaWave suggests - with varying degrees of success depending on conditions and crew. /forums/images/graemlins/tongue.gif
Biggest factors to success (or failure!) are:
- Helm concentrating !
- Crew (trimmer(s), pole dipper and foredeck all really knwoing what they are doing, AND what each other are doing AND communicating - not just getting on with their job in a bubble
I'm sure the above sound obvious - its just a shame that we don't always achieve it !
Reference below is a reasonable overview of spinakers - though the jibe they talk about is end to ending - but most of the rest applies.
Rig the pole on your berth, then raise the heel/drop the nose far enough for it to swing through the fore triangle easily. Then mark the mast track and the topping lift at those points, so you can pre-set the pole to gybe without a screw-up as you find it doesn't clear the forestay.
Keep the d*mn thing in its bag, you can swop it from port to starboard anytime you like then, regardless of wind strength or direction and even if single-handing.
Agree with this. Also worth while hoisting a "rope kite" i.e three ropes roughly corresponding to the tapes of the kite and practacing gybing that a few times to get everyone used to the sequence.
Have to say though that getting one person to trim both guy and sheet through the gybe will only work in light airs or small boats, which frankly is not when problems with gybing occur!
If crew numbers permit I would have - 1 pitman dealing with pole up and down.
1 mast man dealing with inboard pole height
1 bowman to swop the guys over when the pole is in reach
2 trimmers - who need to communicate with each other AND THE HELM
1 floater to help the trimers, grinding if necessary and helping swopping the sheets and guys if you aren't blessed with a billion winches. The pitman can help grind on the new sheet/guy after the pole is back in it's position.
Then the sequence is - wind on new sheet, taking load off guy.
release old guy, pole down, inboard pole up. trimmers trim kite on the sheets - if it's breezy fight your urge to ease and GRIND ON! Kites have less power when flat. The helm and trimmers have to work together to rotate the kite at the same rate of the turn, this requires practice to get it right.
Bowman catches pole end swops guys and pushes pole out clear of forestay on new side.
Pole up, pole inboard end down
Slack taken up on new guy and load swapped from old sheet to new guy.
The common mistakes are - poor trimming and/or helming collapsing the kite.
Not transfering the load properly and releasing a loaded line resulting in a jerk which collapses the kite or rips a line out of the bowman's hand. If this happenes the guilty party should buy the bowman's beer all night.
The bowman getting confused and putting the new guy through the end of the pole the wrong way, resulting in a wrap around the pole end. If this happens the bowman owes the whole crew a beer.
The pitman releasing the pole up too fast and it acting like a javelin aimed at the bowman. This hurts and will cost the pitman a lot of beer.
This is just the kite manoeuvers, the main should be gybed whilst the pole is off the kite.
To trip the pole cleanly ensure that the new sheet is on top of the outboard end of the spinny pole before you trip it. Other wise as the pole is detached from the guy it will hang/drag the clew of the kite down and kill the trim.
Txs for a very efficient walk-through! I have printed and will try better next time.seriously,a great summary!
