I am reasonably new to laser sailing and weigh 92 kg.Our club sometimes has evening races during which the wind will often drop dramatically as the seabreeze dies. The last two times this has happened, I have lost huge amounts of time especially into wind, having been near lead with stronger breezes. Various adjustments were tried ( easing vang, less mainsheet tension) to no avail. Is this always going to happen until I lose 10Kg ? Does anyone have any suggestions?
