My mate's boat has a bad case of weatherhelm, ie he's hauling the tiller to windward and the boat is trying to head up. Not quick. What might be causing this then oh experienced forumites?

First thing I'd check, is the rudder fully down/has the hole in the actual blade worn away and is oval?
A lot of the other points can be checked against the tuning guide |

What sort of boat is he sailing? All of the reasons you have put forward could be correct. So get him to check settings on another boat of the same type or get the info from the class website. If all is correct then you have sailing style and sail setting to look at.

I don't want to embarrass him by identifying the boat :¬) but I would like to help! Big centre-board and an overlapping jib tho. ------------- Javelin 558 Contender 2574 |

| Most boats these days run the lateral resistance between the rudder and cb, which means that its quite difficult to get real weather helm. A video taken from behind would be a good tool. find out i the tiller is really offset and the boat is really flat. |

If it's an RS500, with the XL sail then it's standard. ------------- https://www.ease-distribution.com/moses" rel="nofollow - Foil fun |

| On most boats it's unusual to generate much weather helm just from rig setup unless you are a country mile away from the standard setup. Biggest offenders are excessive heel and rudder not fully down. If it's a SMOD class make sure that the hole is in the right place on the rudder, this can be checked by overlaying against someone else's rudder. Some people add a foam cushion in the front of the rudder stock which can prevent the foil from going fully down. One further idea is to ensure that the wingnut on the rudder is slackened off before the rudder is pulled down with the downhaul. Once down then tighten the wingnut. |

Can't say I've ever noticed significant weather helm with the one at our club...
