Was it John Oakley who claimed that painting the hull with egg white (and allowing it to harden) made a super-fast finish, as it slowly dissolved during a race?
I understand the story was all a con anyway, as the boat in question would be washed off secretly after all the rivals had launched! Mind games... |

On the subject of a slighty round surface. I had a Laser which was covered in brown scum when I bought it. I had you use an abrasive cleaner on it to get the thing clean. When done the surface was slightly matt. I did the ususal after cleaning care (used a polish to seal the hull). But I swear that was the fastest Laser I have owned (I am now on my 4th for my sins). The one I have now has been painted (by paint craft) and I would say it is only marginally slower.
The brand new boat I had felt nice but I am convinced it was not as quick (especially on a reach) as the other 2. Just my 2p.... |

Here is an interesting article on the subject
http://magicmicro.org/e107_plugins/forum/forum_viewtopic.php ?438 And who remembers the days when we used to cover the bottom of our boats in black "Graphspeed" or white (or was it light pink) "Go Fast Paint". |

Well the stuff I researched is almost certainly a texture, a texture which
changes after an hour or so submersion and will certainly improve the performance of the hull, that spray on stuff used to be good for 5% and we proved that over a measured mile back in 1975, but it needs constant re-application. It was however illegal in sail events, but don't think that didn't stop some antipodean application, it's invisible to the naked eye and only becomes viable after a period underwater so very difficult to detect. Another of the dirty tricks us Brits wouldn't consider. Like tuned battens in Olympic OD fleets. (USA) Carbon re-inforced supposed OD centreboards (NZ) Re-inforced Flushing strips (GRE)..

This and everything that is not polished off completely (ie: anything other than say a polish(!)) is not allowed because it leaves a "specially textured surface", and I would argue that that is the spirit of the rule. If that is genuiely the last thing that could speed you up in your sailing then your surname is probably Elvstrøm. |

They're not thinly veiled at all. Anything that comes from an organisation that isn't a club or class is a paid for ad, as I understand it. Anything from any shop should be treated as so. It's what helps pay for this website to run, along with the banner and side bar adverts. It's always been this way. I don't find it that intrusive, either. |

Ok fair point. Having read their website, and your ISAF link then, I suspect that it would only be illegal if it was considered to have a textured surface - I believe that rule is to stop the "shark skin" textures that some AC boats experimented with years ago. Are polymer "branches" a texture??? Their site certainly has some impressive testimonial claims on it - too impressive perhaps. One yacht sailor claimed his boat was 10% faster!! Thats would equate to about a 6 minute advantage in a 1 hour race. Edited by JohnW |
