The 190ft long solid wing sail developed for DOGzilla has been finished. Im sure SNG will have some sort of rule changing prepared to stop BMWO from using it. |

It's looks incredible. Bigger than any aircraft wing that has ever flown. In fact a comparable size to a windmill sail. Hope they don't drop it like the mast last week. That could kill someone.

I don't understand why everyones getting so excited - after all didn't DC race against the big white boat in a cat with a solid-sail, in what late 80's? Ok so size wise it's impressive but hi-tech construction has moved on 20 years, and there's been lots of projects to learn from e.g. C-class and the speed guys n girls. |

Because something like it on anything like this scale hasn't been attempted before. How fast in a straight line are these boats going to be? ------------- Firefly 2324, Puffin 229, Minisail 3446 Mirror 70686 |

regardless of any of the bull that surrounds its existence, there's no doubt that's one awesome looking bit of engineering. ------------- -_ Al |

To put it into context, it's about the height of 17 stories of a tower block. If you're in a town, have a look at one and count 17 floors - it's a long way up. Simon |

The streaming from Fox last night was super. You could see all these boats come shooting up the river and then spot the beast and come over for a butchers. Got told off because the laptop fan was making to much noise. I had it in the lounge with the streaming on fullscreen. I assume they'll take in out again tonight.

| Ther really interesting thing is to see if they actually use it in the event. To overcome the risks of doing so it would have to offer a definite advantage over the best soft sail wing mast technology. The only recent experience of that being tested I know is detailed at http://www.sailingscuttlebutt.com/news/09/0810/ - http://www.sailingscuttlebutt.com/news/09/0810/ and it wasn't clear cut. And downwind advantage presumably won't count for much since it's not a una rig restricted class. |

Not sure that is a valid comparison. On the AC boats, the sheet loads re massive to control the leach on these soft sails; alomost al this goes when moving to a wing as the leach is self-supporting. It will be interesting to see if they add a screacher for down wind work; I've seen a couple of pictures where it appears they have "soft" sails on deck. ------------- Wanna learn to Ski - PM me.. |

So would that suggest the boat would have to be designed as wing specific to gain the maximum advantage ? I mean it's carrying the structure to cope with the loads even if the wing negates the need. Not sure if the old Stars n Stripes used to fly a hull - probably didn't need to bother racing a mono. But you do wonder how much damage would occur should the unthinkable happen and it went over. Not too any people have experience of handling 180ft wings after all... |
