Hey Folks,

Does anyone have any information about average expected speeds based on sail angle? I think it may be called a Polar Chart but I'm not sure. Thanks.

Either a polar plot or polar chart. If you do find it, please post on the website (I guess in the specifications section?). Iím sure there is one published somewhere.

I'll be dammed if I can remember where I found them but here is a spreadsheet with the T-37 polars.

This is awesome! I was literally just looking for this last week as we were preparing for our crossing from the Keys to the Bahamas. We got a subscription to a fancy new weather routing software, and couldn't find a polar chart so I made some educated guesses....

Based on my experience these numbers feel a bit high, but it may just be that we're fully loaded for cruising and so Soulianis is a little more sluggish now. But these feel close enough to start playing with, anyone else have an opinion/data?

Thanks again for sharing!

Thank you for the quick response Wayne. I thought I would get a notification if someone responded so Iím just seeing this now. Now I need to decipher what Iím looking at. Very Happy
