Using an alternate Polar chart
When Optimising can I use an alternate polar?
e.g. I have a polar table under Tab "Pol8" can I tell the Optimiser to use that rather than the polar table under Tab "Nav"? If so how?
Thank you

No, you cannot. To run an optimisation on a different polar you would have to load that polar as the Nav Polar.
The optimisation by pol% is a very effective way to test how sensitive routing is to speed differences in a polar.

OK Thanks Campbell,
Out of curiosity where are those other Tabs used; what are they for?

I have two different boats: different 10m wind scaling, different polars, different sail charts. How best is this handled to avoid changing these settings back and forth?

Hello,
They are used it you want to make a polar of something like keel angle.
Unfortunately, if you want switch between boats, you need to manually select a different polar.
