Around 25% in every class I've ever looked at - or 250 points of PY. The results from the last Olympics are fully timed, makes interesting reading... http://www.sailing.org/olympics/london2012/results_centre.php Now I think about it its kinda suspicious that the range seems quite consistent between very different classes and even similarly wide at the Games. I wonder if its as much dominated by a tendency of mark roundings to force everyone into single file as anything else? Maybe there would be a difference between long races with few mark roundings and shortraces with many. Might be an interesting thing to research. Edited by JimC - 03 Oct 14 at 10:59am |

I always took that to mean one duff shift, rather than the physical act of transitioning the boat from one tack to the other, I mean how can that go wrong? You shove that wiggle stick and round it comes.
I accept maybe in some boats in some conditions like mine with its full batten sail the flow doesn't re attach too quick in light wind, but the answer to that is simple. Have a different sail made. ![]() Edited by iGRF - 03 Oct 14 at 11:01am |

Only 5% difference for the Finns - which is not unexpected - you'd expect closer racing at that level.

From observing those when I've been running coaching, the old 'tack on the whistle' drill can clearly demonstate the benefits of tacking well and the gains possible...
Context does have a part to play here though too. A 'must make this tack perfectly into this gap of boats to lay the windward mark' is clearly more important manouver to get spot on than 'I'm on my own and should probably tack soon to cover the fleet'...
Pressure can make even well practiced folk feel like they've two left feet at times...

It has it's place, as does gybing on the whistle and and quickly expose bad technique and provide coaching points. I do find that using a downwind slalom course can be a lot more fun for the people who are taking part especially if you set them off at 30 second intervals.

but dw slalom courses are a bitch to lay for a simple training exercise.... best reserved for snaking and carving moored sailing yachts in rivers and estuaries

Unfortunately the tacking on the whistle exercise is often seen as a 'warm up', or not analysed properly. Too often the tacks end up rushed and get worse and worse. For me a better exercise is boat on boat covering, where a duff tack is quickly exposed, and concentration much keener.
Of course the absolute best is video analysis, but not everyone has that facility. For me a good tack is where I don't oversteer, get my feet straight under the toestraps on the new side and get the boat flat and driving asap. The reality is more that I will oversteer then miss the central kickboard and slide down to leeward without the grace of Jane Torville, leaving me an uphill climb to the new side where I then have to hoist myself out onto the wing... Dont even mention the duff gybes, |

the same, but different...

I was amused by a comment from the runner up at the IC worlds (in San Francisco) on another forum...
You have to appreciate that was not only the wind strength, but the matching wave systems that cause the problems... |

25% ... That makes people who bitch about a few points on py look a bit daft. |
