Hi all,
I have created the below polar based on the published speedguide from Hanse. note that although the speedguide shows a speed gain at lower wind speeds to go with the spinnaker, I have reserved the switch to spinnaker for 105 degrees through 165. Hope others find this useful: tws is true wind speed twa is true wind angle bsp is boatspeed in kts tws twa bsp twa bsp twa bsp twa bsp twa bsp twa bsp twa bsp twa bsp twa bsp twa bsp 6 0 0 45 4.6 60 5.57 75 5.91 90 5.85 105 6.39 120 6.05 135 5.25 150 4.23 165 3.58 8 0 0 45 5.73 60 6.78 75 7.2 90 7.08 120 7.48 135 6.54 150 5.5 165 4.7 12 0 0 45 7.2 60 8.3 75 8.6 90 8.5 120 9 135 8.4 150 7.5 165 6.68 14 0 0 45 7.5 60 8.6 75 9 90 8.9 120 9.5 135 8.97 150 8.2 165 7.5 16 0 0 45 7.75 60 8.77 75 9.32 90 9.34 105 9.96 120 10.03 135 9.45 150 9.3 165 8.2 20 0 0 45 7.86 60 8.9 75 9.52 90 10.2 105 10.19 120 10.8 135 10.48 150 9.72 165 9.2-Chris P.S. I have also asked PredictWind to add this polar to their "predefined" list |
