When racing, dirty air is a huge tactical feature. Going upwind, I often see a leeward boat, very close, on the same tack, passing like a rocket. Also, when reaching, dirty air from a closing boat from behind should make you slow down a bit. It would be a great feature to add telltales on the jib and follow wind shifts with them. Just saying. Great game otherwise and I hope to see you on the VR water guys. Cheers!
