We might be thinking about making our 49er fully foil at some point. I've researched the subject and don't worry, we won't rip the transom off the boat. Anybody interested in the project? ------------- Dennis Watson 49er GBR735 http://www.helensburghsailingclub.co.uk/ - Helensburgh S.C http://www.noblemarine.co.uk/home.php3?affid=560 - Boat Insurance from Noble Marine |

Ive seen a couple of pictures of a 49er trying to foil but the word at the time was that it was totaly uncontrolable IIRC

Going foiling on a 49er sounds like it will be very wild ride indeed. Having watched a couple of Moths at Grafham yesterday the landings look fairly harsh and staying on the wire in similar situations I think will be a challenge ! There is video around of an International 14 foiling and it looks like a good giggle ! Might be worth trying a B14 first as the landings will be less messy! If you do decide to go the 49er route, can I come and watch please ------------- Wanna learn to Ski - PM me.. |

Agreed, I think thats the biggest problem to get round. Sat on the wing of a moth you can lock yourself into the boat quite well, I wouldnt fancy crashing from the wire at all though, I think it would really redifine the phrase 'world of pain' I believe Linton Jenkins, of Fullforce Boats fame was experimenting with a foiling RS600 but as ive heard no more of it I guess it was not a great success. If anyone in the country understands how to make hydrofoils then its that chap so I can only assume the failure was down to the boat being unsuitable, very probibly because of the wire. Having said that if anyone knows anymore about the project please feel free to correct me, What I know is only from rumors really. A B14 on the other hand... now theres an idea.... Ive no idea how much they weight but on first impresions id say they have a lot greater foiling potential than 9ers. ------------- |

im still up for it! it doesnt take much speed to get the moths foiling any way and the crashing doesnt happen when you get into how to work the foils, the "harsh landings" only occur when the centre foil cavitates, sudently loosing lift and falls back down, you learn a feel for your ride height and control it thorugh the rudder foils, with practice, its not so hard ------------- http://www.noblemarine.co.uk/home.php3?affid=561 - Competitive Boat Insurance From Noble Marine FOR SALE: I14 2 Masts 2 poles 3 Booms, Foils Kites/Mains/Jibs too many to list. |

The previous attempt made to foil a 49er was reasonably successful. The only problem was the wing on the rudder was too far up the foil. I reckon if the wings on the rudder and daggerboard are almost in line with each other, there won't be too much of a problem. It has to be tried  ------------- Dennis Watson 49er GBR735 http://www.helensburghsailingclub.co.uk/ - Helensburgh S.C http://www.noblemarine.co.uk/home.php3?affid=560 - Boat Insurance from Noble Marine |

does indeed, You can quite easily have it set up the same as the moth with the foil at the base of the foil, and then the trailing endge of the foils doing the movement! its proven to work so why experiemtn with that and waste potential air time... ------------- http://www.noblemarine.co.uk/home.php3?affid=561 - Competitive Boat Insurance From Noble Marine FOR SALE: I14 2 Masts 2 poles 3 Booms, Foils Kites/Mains/Jibs too many to list. |

thats another way of doing it, yet the reason thaat design was banned from the moth was becaue it creates multihull like stability which is against the class rules, in many of these development classes actually. Im not sure if the wings on a 49er are strong enough for that.... ------------- http://www.noblemarine.co.uk/home.php3?affid=561 - Competitive Boat Insurance From Noble Marine FOR SALE: I14 2 Masts 2 poles 3 Booms, Foils Kites/Mains/Jibs too many to list. |

in de old days there was a tornado named icarus that had similar (to look at in pictures !) foils to those on the the 18 , they pretty well perfected it ,and the boat from whit I remember flew consistantly , only drawback (as far as I can recollect) was that it was no faster than a standard Tornado . so dissapeared into obscurity (relative )
James Grogono was the fella for those looking fra piccys , if available on web ! ------------- |

The 49er wings would not be strong enough, unless you reinforced their mountings to the hull, which would cause more work and by doing so, it may be hard to convert the boat back to a legal form. It would be nice to get the boat foiling but I'm not planning on sacrificing the legality of the boat to do it. The foils that will be put on the boat will have to be easily removed so we can still race the boat properly. ------------- Dennis Watson 49er GBR735 http://www.helensburghsailingclub.co.uk/ - Helensburgh S.C http://www.noblemarine.co.uk/home.php3?affid=560 - Boat Insurance from Noble Marine |

I believe that the 49er will hydro foil easily you will need 12+knots of wind. The 49er has a large wetted surface area at the transom. So you will need a strong wind to be able to do that. Thats why the moths are so good for foiling cuz of the small wetted surface area.
i think the foiling rs600 is still work in progress, they have had it foiling they are just refining it. its ment to be awesome!! ------------- Cheers Dudes |

Sorry should have put some text on, this is Clive Everest's version of a foiler about 12months ago. Looks pretty sorted, but I think he had issues and has gone back to drawing board. ------------- Drink Feck girls! |

From looking at the Bethwaite site, its seems they've started selling them in Austraila, they have prices and methods of conversion on the site. Shouldn't be too long until Ovington Boats start selling the rigs. ------------- Dennis Watson 49er GBR735 http://www.helensburghsailingclub.co.uk/ - Helensburgh S.C http://www.noblemarine.co.uk/home.php3?affid=560 - Boat Insurance from Noble Marine |

It owuldn't be to difficult to use the same system as the moths and still make the boat class legal. ------------- http://www.noblemarine.co.uk/home.php3?affid=561 - Competitive Boat Insurance From Noble Marine FOR SALE: I14 2 Masts 2 poles 3 Booms, Foils Kites/Mains/Jibs too many to list. |

Andy, the 49er should be down after xmas, and would love to go out in aqua at any time. Been doing keelboat stuff recently but getting really bored........ Are you considering doing any of the student events in aqua or are you going to concentrate on the scorp'? ------------- Dennis Watson 49er GBR735 http://www.helensburghsailingclub.co.uk/ - Helensburgh S.C http://www.noblemarine.co.uk/home.php3?affid=560 - Boat Insurance from Noble Marine |
