Looks like the MS is only good for 23knt TWS @ 145TWA according to the VMG chart for downwind.

Thanks for the reminder. I haven't noticed it in the briefing. Will take a look. Have to remove C0 from non-pro sails too.

Okay, going out on a limb here and hoping I don't make too many people choke while laughing at my lack of knowledge. On the Wiki page that discusses sails there are two very colourful charts outlining optimal upwind and downwind VMG's. I thought you needed a destination to get VMG. What are they referring to? Maybe I have to go and Wiki search for VMG and get educated!

VMG is given for direct upwind/downwind, so no destination needed. IE, the tables give the best VMG for getting to any point that is directly upwind or directly downwind.

I sort of figured that's what they meant Flag_em but I wasn't sure - thank you!

The now polars should be active now. Let me know if you spot any differences.

Do you have the .csv file for the new light spin polar?

You may need to do some search/replace.

Thanks zvetan for new LS file sharing ;)

I saw what they fixed. The VMG charts had two peaks at 18kt wind - one around 145 coming from the MS and another one around 155 from the LS. The second one is gone now, and if it was not the auto sail would probably put the sail outside of its supposed range and break it.
