| Post subject: | Batten Sanding |
I am looking for information on batten tapering. Is it true that I can sand down my stock battens any way I want and still be legal? What do the racing experts do with their jib battens? Depends on the wind I'm sure. Saw some posts suggesting it is OK to do. I have a spare set I would like to experiment with by sanding the luff ends but don't want to waste them. Have cabin fever. Thanks. |

Most either 1) leave them alone or 2) make the top two softer to get more curvature in light airChrisD wrote: Depends on the wind I'm sure.

Thanks for the advise. Outside with a mask is the only way for me. Only the top two? I would have thought the lower ones might pass easier if they were beveled but the trade off is that the sail shape is compromised I suppose. Always a trade off. I won't over think it. Will do the top two. |

Kim Miller is well intentioned, but uses the wrong terminology and concepts when it comes to sail shape / battens / batten tension / air flow. |

Perhaps flawed but a good article nonetheless. It was worth the read and does give, me anyway, a better understanding of some of the forces in play and variables as well. More of what to think about than what to do. Thanks. |
