Difference between vessel heading and apparent wind direction and apparent wind speed must be provided. Note that if apparent wind speed is supplied in knots, it is necessary to supply the ship speed in knots. Click on Calculate. WebThe sail is intended for angles between 110° TWA to 145° TWA in wind speeds between 15 knots-25 knots TWS. To make it perform well at these angles and wind speeds the girths are slightly smaller than on your full size runner. Also the head angle is slightly reduced to make the sail forgiving when you sail at high angles. Size factor: 80% of S2. how far is slidell la from hattiesburg ms
