Nope, its a fundamental feature of the 600 rig. Its not really an issue for the 600 owner, because the sail is cut for the way it bends, and they are all the same of course, but with lowers the boat would be a tad faster and the rig a tad more controllable. |

Original
 This picture is the best picture I have that shows the current rig and sail shape. I'll take some pictures of the whole rig at the weekend.  |

Not looking to win any national championships in this boat. It's a learning boat and after a few seasons I'll look into either upgrading it to an 05' rules rig (a massive project!), or sell her on and get a new boat. Currently using using Batt sails, like the ones in the picture you sent me. |

Yeah but the rs600 rig was a compromise because of the perceived need to reef the sail - by shrinking the mast.
The diamonds mean that it is simple to reduce mast height by just removing the bottom, and shortening the shrouds. However, proper control over mast bend is lost. The 600 rig is based on moth rigs of the late 80's, but reverts to the bad points of the moth rigs of the mid 80's. Moth rig development in the 80's saw the boom being attached at the bottom of the mast, thus removing kicker induced lower mast bend. This was a problem in the magnum 6 era, with the nast bend being huge at the bottom. with a straight topmast, making it difficult to depower. magnum 8 and axeman onwards, the lower mast bend is independent of the kicker, which only affect the upper mast and flattening of the top of the sail. But the 600 has the old-fashioned style horrid lower mast bend, but straight mast and full sail at the top, making it much more difficult than it could be. re cherubs, the now normal double spreader rigs and lowers allow the use of light masts, that are stiff enough, flex nicely to allow auto depowering, support the 2 trapezes, big kites, and don't invert. The wires hold the mast in a bent shape, so the sail shape stays similar until it gets windy, then the top flattens, twists and depowers in a low drag fashion. Matching the luff curves and mast bend and prebend is tricky, but when it works it's fast! |

You need to put that in perspective : you're not buying a 27 year old boat and expecting to win the Champs I hope, and in any case boat speed is irrelevant until you are staying upright round the track in 90% of your races. This was early 90s. I don't know what's happened with rigs since. Personally I think it was one lousy set of sails. I don't propose to name the sailmaker, but they were not 97 rules sized sails. I wouldn't worry about it - honestly! I'll send you a pic showing the offending rig... |

Has the boat speed been sorted out? New sails and new sail shapes mean other things have to change, so some experimenting will be needed I think.
