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

P.S. I have also asked PredictWind to add this polar to their "predefined" list
