Because cats all cat hulls (to all intence and purposes) have similar resistance curves and polar speed plots a formula has the possibility to work very well. However because different types of dinghies work differently (eg the difference between types of spinnaker) such a formula will never work as well and so a returns based system is as good as any.

Not so true. Where mono's plane (or not - Most boats will plane eventually Sprint 15's (Dart 15 as was), Prindle 15's and the like are low-power so fly their hulls later, A class fly their hulls much ealier (around 5 kts). So there are some "good winds" for Sprint 15's - Lots;and good winds for A class (less windy). So there is some wind strengths were the S15 will benefit at the A's expense. I would agree that the hull shape of a mono has much more effect on the boat speeds - e.g. 49'ers don't do well in the V light stuff as they have a lot of "boat in the water" than say a Laser or Ent. To answer the other point about comparing the handicaps, take the SCHRS handicap and multiply by 6.841 to get the approx PY : Hurricane 5.9 is SCHRS 101 and PY 691 101 * 6.841 = 690.941 = 691 And then apply any PY "weighting based on returns!!!!!!!" Shadow SCHRS is 107, PY 732, BUT Inter 17 SCHRS is 107, PY 735 (this maybe because I keep washing the sails in "open" opens at Grafham |

Never, under any circumstances, take a sleeping pill and a laxative on the same night.

Dropping the mainsheet is the normal culprit. Poor Simon, he had a beast of a Nationals judging by the results and this photo. More photos @ http://fotoboat.thirdlight.com and www.photolounge.co.uk Edited by Matt Jackson |
