Here you can find a real polar/butterfly graph. As you can see, in a TWS 12kts :

- TWA 035° : ~6 kts

- TWA 180° : ~4kts

So, it's not "physically impossible" to proceed at TWA < 45°. Besides, you still get a 50% better speed than at TWA 180°.

Note : that was 10 years ago. Considerable progress has been made.

Unfortunately, in a game, everything is theoretical. I wish I could feel the sea spray in my face, sitting on my sofa.

 

Thank you for posting this - it does support the case for the parameters used in the game.  I still think the extremes upwind and downwind are a bit unrealistic but probably compared to other things like the indestructibilty of the virtual boats it is not that big a deal

Exactly these does not remotely correspond with physical reality - show me some data for an Imoca 60 travelling 35 degrees upwind in 10 knots of wind or going zero knots when trying to go 180 degrees down wind in 10 knots

I understand that but with the drag on these monohulls they can only ever advance beyond 45 degrees using apparent wind  when foiling or possibly in 20-25 knot winds. The VR game allows boats to head at 28 degrees in 10 knots which in reality is impossible. Show me some real data not theoretical calculations that ignore drag.

Why does VR allow boats to proceed upwind at less than 45 degrees? This is physically impossible a there is no foward driving force. Also going downwind there will be a speed penalty for going to low but at 180 degrees you shoukd still make forward progress. Basically to obey physics the "polar" should be asymmetric

Ah yes! Indeed, you go from afar!

The polars are the speeds that you can reach with a given force of wind, such a sail in such a direction.

It is not you who decides ... Nor me for that matter!

So, as Franck suggested to you. Take an interest in speed thrillers and you will have your answer.

I find it bizarre the way the polars are set up - they should not be symmetric - physics dictates that going upwind lower than 45 degree you have  no forward driving force at all - speed should be zero or even negative.  Going downwind there is always some driving force so although tighter angles will be faster you should still be able to progress at 180 degrees
