Speed creases on main of the new boat: Luff starvation creases on the old boat after the whipping on my makeshift Kevlar lower shrouds had failed, allowing excessive mast bend; note that the creases run from luff to clew. Jockeys in this pic not including me but Mr & Mrs Foxwell (of this forum): |

The cool dudes on the reaching 470 are Nic Asher and Elliot Willis, going just about as fast as you'd ever want to go in a 470!
Notice how Nasher is steering - gripping the extension right down at the base for lots of control. |

A lot easier to keep your footing in big waves than in sharp chop. The baiscs are: Good boots pro-grip on the rails (look at the boats) and most importantly lots of effort- you need to read the waves and absorb the rolls and thuds with your legs. |

..Here's the video, http://www.dailymotion.com/relevance/search/sailing+/video/x 13f4_dinghies-a-go-go_sport they do look fantastic [/QUOTE] Superb video. I've just watched it half a dozen times. How do the crews keep their footing in such waves? I especially liked the cool dude on the reaching 470 with the blue spinnaker. |

Besides speak to a sail maker he will only tell they get pulled out when the camera is out and focused on them!

Those overbend wrinkles used to be called "speed wrinkles" by 470 world champ Steve Benjamin and others. In some conditions and boats, they are the fastest way around the course. Sure, you can straighten the mast low down - but that will increase the depth low down, overpower the boat more, and slow you down. Same with extra luff curve.
Lots of classes sail fastest with wrinkles of various sorts. The boundary flow may be so turbulent in those conditions that the wrinkles will have almost no effect on drag, I s'pose. |

Ok but I'm sure it would go even better upwind without the drag of that crease and that crease is caused by the mast bending too much for the cut of the sail. It just needs a tad less bend in the lower part of the mast - or a sail with a little more luff curve in the lower part. |

Some of you lads really dont have a clue what you are talking about. If you have a boat without a kite you still have to get downwind. Accordingly you will likely opt for a fuller rather than a flatter mainsail in order to have more power. In order to deal with the power you will get a flexi rig so that you can bend the mast upwind so as to flatten the sail and then sail with a straight mast downwind when you power the rig up. The main sail on such a boat is the engine both up and down wind and has to be able to cover all wind speeds. Think about it. It is not easy. A really interesting boat to learn about how and why your rig does certain things. Also it makes you aware of how beneficial it is to have a rig which can operate at high and low windspeed. I know it helped my sailing. This rig looks a lot more right than wrong. |
