Hello
In the number box, Sail, Sail Mark, Sail Next Mark do not show.
In all other place, like route ou routing plan, sails are present.
I use Sailing performance sail chart.
best regards

In the route it is based on predictions...
In the number boxes it is based on current instrument reading. I would suspect you are missing some bit of instrument data to calculate the sail.

Hello
I have : Boat speed, AWS, AWA, TWS, TWA. It should be enough.
I also have TWD (True and Magnetic), Course (True and Magnetic), SOG, COG
The Polar Boat speed works well, and target angles. VMG and CMG calculation works

It all works ok here. Do you have an active mark?

Hello. I have the same experience as philippe. Sail and SailNext do not show in the Number Boxes. Was there a solution to this? Thank you.
