These are actual routing calculations done by Cirrugator for the Pacific Cup 2014 race. The red diamonds mark the calculated best route for the chosen boat. The red arrows represent the wind to be expected along the course. The black lines are the isochrones, thick lines for full day, thin lines for 6h intervalles. A red line with red circles - when present - marks the actual course of Cirrus (Standfast 40) in the PCup 2010 race; it is given for reference.
To route by yourself, go to the Cirrugator Easy Routing site, select a boat and press the Go button.
For more details see the explanations on the DEMO site of Cirrugator
NOTE: If you can provide polars from other boats, I will gladly take them and integrate into the router. Use this link to contact me.
