Jyrki Enclosed the same table for the standard rig. The extra tall rig can be expected do show roughly the same differences compared to the tall rig, as the tall rig shows compared to the standard rig. Should I work out a new table for you? Kind regards Lars |

Dear John Doing well compared with the other boats would suggest there was enough wind. Many yachts use a 130% furling headsail as a good compromise giving easier handling with more or less the same performance. This will lower your rating slightly, and make the yacht more competitive when it blows, but in light weather she suffers somewhat. Kind regards Lars

John Upgrading the mast to a two-spreader section might not be a good idea as this increases the IRC rating. The goal of the rule makers is to make the rating correspond to the performance. The boat with the low rating probably reduced rated sail area, this gives an advantage when it blows, With two spreaders the load distribution in the shrouds changes, V1 sees more load and D1 less, and this causes changes in the shroud and rigging screw pin sizes. Kind regards Lars |
