Has anyone figured out a way to develop and implement polars for a specific sail plan, such that the Nav polar table would be automatically updated for the current sail selections?  I understand why a professional race program wouldn't necessarily need to do this (they would always want to be using the fastest sail for the conditions), but for us, we're constantly making a decision as to whether / when we want to change sails and we're often using a non-optimal sail plan.  So it would be helpful to have a dynamic polar table that reflects the polars for the current sail choices.  

Here's an example of the issue.  Our downwind tradewind sail has a TWA range of 150-180 degrees and a (somewhat simplified) wind speed range of 10-23 kts.   We have a set of polars for that sail within that range.  Our alternative downwind setup would be wing-on-wing main/poled-genoa and we have a set of polars for that setup.  We know that we could easily have multiple polar files and move from one to the other, but the challenge comes when we want to make a change to a section of the polar file for a different sail.  For example, we want to tweak the upwind genoa/main polar.  If we did that, we would then need to consciously propagate that tweak into each of the downwind polars.  Likewise, making a tweak to the polar of our reaching sails would require making that same tweak in each of our other polar files.

An alternative way to implement polars would be to have a polar defined only within the range of each sail plan and then let the software logic compile the individual sail plan polars into a master polar that is used for routing and performance monitoring.  

Given the expertise out there within the Expedition community I'm sure that others have figured out how to manage this with the tools that are out there.  If anyone has any suggestions, it would be great if you could share them.

Thanks!
