| Post subject: | Hobie Mast Rotation |
Am a relative rookie and am trying to defend the Hobie image against a couple of Dart 18's in the local area. Am using a new sail on an older boat and the mast rotates all the way to the the stop, consequently the mast is almost ninety degrees to the wind causing slight luffing of the main immeditely aft of the mast. I am certainly loosing some power and find I can't point as high as others Don't recall if it happened with the OLD sail. Shroud tension, etc, seems to be in accordance with the recomendations of this forum but am not sure about down and out hauls on the main. Anybody know what rigging or tension changes are needed to keep the mast in line with the sail? Thanks. Pete |

You don't want the sail in line with the mast. It sounds like you may want a little downhaul. Are there any strong racing type people that sail Hobies near you? |

downhawl sounds like what you need. the main sail makes its power from the wind traveling around the main sail like an airplane wing on its side. downhawl is pressure applied to the bottom of the boom (next to the mast) by a line running from the the bottom of the gooseneck to a cleat lower on the mast and is usally tightened until the wrinkles are removed from the front edge of the sail. as recommended find someone sailing the same boat as you and see how their boat is rigged. you can also find a local hobie fleet in your area and the sailors there will be happy to assist you good luck and good sailing |

It sounds like to me that you are back winding the main with the jib. If outhaul and downhaul don't work you can always move your jib car a bit more out to the side of the boat (there are times when you don't want your main sail pulled to the max in every direction, but that's another post). You want it to the point where it is almost back winding the main but not quite. If it's set too far out you won't get enough air movement across the back of the main. If it's too far in you'll be back winding the main causing you to slow down big time. Good luck, Adam |
