6 OPTIMIST TUNING GUIDE VANG OUTHAUL DAGGERBOARD Should be just slack upwind in light/medium conditionsTighter when windy.Vang should be tight enough to hold the sail shape on the downwind leg.Smaller sailors can use the vang to help depower the boat.OUTHAULOppy sails are flat so only have the outhaul tight when its very light winds or blowing a gale.Most of the time you want a nice smooth curve.DAGGERBOARDMark on your daggerboard the positions for beat/reach/runLight sailors will find lifting the daggerboard up 6inches (15cm) in strong winds will help them control the boat and allow them to sail upwind more effectively.
