We have a symmetric spinny with a double ended pole. Over the years we've tried several different routines, we've now settled on one that suits us. Bear in mind that the crew is a small (but perfectly formed) woman so anything that makes the pole difficult to push out will not be favoured by the boss. I also want to stay within class rules so no double pole systems or tapered sheets.
The sequence is usually: Gybe, crew hands guy and sheet back to me to feed or tension as appropriate, crew swaps ends on the pole, I cleat the new guy in roughly the right position, I hand sheet back to crew. We're not bad at it, it usually goes smoothly but we cannot keep the kite flying through the gybe consistently. It sometimes stays inflated but mostly doesn't. I've watched the 2012 Olympic 470 vids, how do they do it? Am I expecting too much or are there some tricks to this? Edited by transient - 13 May 15 at 1:17pm |

Where in the gybe are you tending to lose the kite? If you can borrow one a Gopro on the rudder during an extensive practice session might be enlightening.

Here's what we used to do in the Lark years ago. Before the gybe the crew uncleats the guy and bundles up the spare sheet inside the boat, taking out all the slack. Immediately after the gybe she hands it to the helm who can now play the kite with one hand, moving it backwards and forth as required to keep it full. The crew then changes the pole over as normal, the beauty being that there is no longer any rush as the kite is being kept full by the helm. Crew then takes bundle from helm and plays kite as normal.
It's much easier on a run to run gybe or when you have room to do a nice smooth reach to reach gybe rather than having to luff after the gybe mark to keep your wind clear.

One of the issues with a double ended pole (I assume you mean it is supported by the rope in the middle?) is once the pole is un-clipped from the mast and the kite is pulling it is very hard to push the pole back out on the new side and clip the new end to the mast. This is because the pole pivots in the middle and a tight guy multiplied by the leverage of half the pole can overcome the strength the crew to raise the new pole end to the mast fitting.
When I had my young kids crewing I switched to a single end pole system where the pole support was fixed to the outer end of the pole. It completely eliminated the fight to get the pole end clipped on. It is a bit more of a faff and the pole must sit on the boom when not in use but you soon get used to it.

Might try the camera although it might be better filmed from a safety boat. I'll see if I can rope someone else in for that. From memory the kite deflates at about the same time as as the gybe, so by the time the sheet and guy are in my hands we've already lost it.
crew uncleating before the gybe. Mmm.....I'm not sure but I think the crew already does that. Nice description though Steve. That's pretty much how we do it. I've looked at the single ended pole several times over the years, never actually tried it though. The idea of stashing the pole before the gybe bothers me, when redeployed it's going to be on the wrong side of the boom....this just seems awkward to my mind. Perhaps we just need to try it and see, it may be easier than I imagine it. |

Hi
I think the pole trapped on the other side is down to you to make sure the main is in slightly. On losing the spinny when end to end gybing its a co ordination thing, you need to steer to keep the kite full also make sure the guy is released from the pole before undoing it from the mast( as it drags the clew into the wrong place promoting collapse you may need to turn the end fitting of the pole round depends upon kite size and pole height), possibly pulling the guy back further than you think as you square the boat to the wind to keep it full. Go out not racing and do it really slowly in light winds to try to crack it. Good luck you will sort it with practice. |

I have a knot in the main that stops the boom touching the shroud so there is a little bit of room for the pole. It's a long pole though, 8' 3" makes it an unwieldy bugger, it'll have to be pushed out parallel with the boom I guess.
we have the pole fittings facing down so the guy "drops" out of the hook. Releasing the guy before removing the pole from the mast....that could be the issue. Jims idea of a video would clear that up as I can't see whats going on in front of the main. Would you say that the correct position for the kite when going into the gybe (run to run) is centrally forward i.e. center line of the spinny in line with the center line of the boat?

Ta for that, it was partially helpful. I did check out that video a couple of days ago but it doesn't cover swapping the pole over.
As indicated by some of the posts I think this requires a step by step analysis of what the crew is doing and what I'm doing, we probably need a third person for that, either as a coach or holding a video recorder. A collapsed kite for a few seconds isn't a major loss but it would be extremely satisfying to get it right as a team. We're getting older, what we're losing in physical endurance/agility needs to be made up with improved technique (Well, that's my theory anyway ![]() |

Just don't mention to your crew that she is getting older and more decrepit!
