Agree with you Roy. They key is to know what you can make work for your crew (weight, preferences etc). There are loads of variables, and of course the aim is to have a setup that allows you to change gears smoothly when you need to. That is - of course - the difference between top crews and the rest.! |

I suspect this is very true; if all this development was making boats go faster wouldn't the 470 & Fireball (and other classes) have seen a gradual reduction in PY over the last 30 years whilst the SMODs stayed fixed ... |

fair point rick but the fireball handicap has dropped in the past ten years was 991 probs about 7 years ago and now its down to 982 which is a fair drop for an established class |

It would be interesting to see a historical graph plotting PY against years for some of the established classes; I wonder if anyone has the data for such an exercise? I suspect it would be depressing to see how little PYs have dropped given the development effort especially as new materials and sailcloths have become available. Especially for some of the classes that have had significant rule changes like n12, Merlin & Phantom. |

That's a great theory except that Merlin Rockets have deck stepped masts and the spreaders are really high up. |

But merlins do use lowers and pullers to fix the bottom of their masts where they want them, therefore giving the sort of cantilever effect that jim C mentioned.

New sail cloths and materials have changed the speeds of most classes. The Yardstick system gives reletive speeds between boats, therefore the handicaps don't reflect all the speed changes that have taken place. The most obvious change was from cotton sails to man made fibres, but as most classes changed within a fairly short period of time (less than 10 years, certainly) they all got quicker. What you would see, though, is that if you took a 1965 Enterprise straight out of the box exactly as she was new in 1965 and raced her against a 2009 one, the 2009 one would be far faster, dispite the Ent having one of the most stable handicaps. You would probebly even find the same thing with an early 70's Laser, as the sail does seem to have been improved, and the controls are far better. Of course, this also partly explains why the handicaps of development classes have changed less than you'd think, as they are getting faster against a moving scale. |
