Has someone heard about this?

Actually, yes (decided not to try), but what I'm really wondering,
there must be some really good jokes about "Excess" "Catamarans", no?

All I can come up with is this

Boat rental: "We have Excess Catamarans!"
Skipper: "Oh, we are 15. I think we need XL."

I just registered to see if I can get to some kind of polars ;-)

The user interface is quite primitive, no projected track, which may mean there are no user-side polars. The 1-hour position update interval mentioned in the manual does not sound very promising either.

Correction: The polars are actually available in json format, not very different from the current VR implementation, but they lack explicit data about wind angles and speeds, so need a bit of reverse engineering.

Thanks Zezo, if you do something can you tell us here?

Data is quite simple. Linear u/v based wind interpolation, polar points spaced 5 knots/degrees apart, [13][37] array.

Sail selection is somehow different than VR

Spinnaker is always faster downwind, with transition angle dependent on wind speed. Upwind sailing uses Genoa->Foc 1-3 with approximate transition speeds of 20-25-30 knots.

Ill build a router page in the following days, but have to get rid of some code first - mostly the pro sails and the complex interpolation.
