 Topic: Battened JibsPosted: 15 Mar 06 at 8:38pm |

How'd you mean?? So far from what time ive done in Rs800's and in Laser 4000's the jib goes across fine in the light winds. They arnt set with anywhere near as much tension as a mainsail would be so its not like they have to be "popped" through a tack, if thats what u mean........? |

OK thanks, I haven't had any experience of them myself so I assumed that they would be under similar tension to a battened mains'l

I hoped the threat would be enough!

I think fully battened sails do last longer. The 4000 jib however bashes its lower batten on the mast each time you tack which wears the jib at that point. Sometimes the lower batten doesn't pop in very light winds (although when its that light you should be in the bar). The heavier stiffer cloth that fully battend sails are generally made of do make the sail difficult to read in the light stuff but my jib still motor boats in the strong stuff but then it is a bit old and tired. There's no doubt in my mind that a fully battened main with a large roach is a much more powerfull sail than a similar sized conventional sail.

Question - why do some newer design jibs have battens? Answer - generally because the sail designer has added some roach into the sail and it needs support. Question - Why is roach and battens a good idea? Answer - it allows the jib to blade off when you ease the sheet rather than just twist at the very top and go super full at the bottom. And yes they do help reduce flogging and help extend the life of the sail. |

The only downside that I know of is, breaking the battens. this is usually down when swimming

tbh arnt we all stating the overus hear of corse battons make you sail more power full and make them last longer how meny times do we have to says this befor people will stop talking about it and the also help to soport the sail thats why that large cats (f18 ect) can now have such tall sails because the full lenght battons soport the top and you done get the twist you would get with out them
end of story move on |

Very naive response to an interesting debate! Personally I find blobby’s comments about roach and the affect of the batten’s on the twist of the jib very interesting. I can see more use for this on your average club boat than I can for a fully battened main, which for the average club sailor can cause more problems than it solves. So why aren’t boats making more use of this affect… or is it just the practicalities of fitting the jib, controlling the slot etc that are restricting this. Ian |

Well let the thread progress and keep your pointless comments to yourself. My boat has a fully battened jib but I think it is interesting to hear why they have evolved to be this way.
It's one thing buying a Strict One Design where all the sails are the same, but when you have the opportunity to have some input in the sail plan it's good to know WHY these things are done and not just take it for granted... (The point of this post is not meant to start a Development vs. SMOD debate!) Edited by timnoyce |
