Hi I have dreadfleet love the game.
Wind gauge changes everytime a player uses their fate card so the left number at the bottom of the card represents wind strength. The number on the right represents how many spaces the wind gauge moves and which way for example wind gauge is at 4,6 you draw a fate catd thats strength (3) and moves 4 spaces clockwise it is now at 5'4 heading.
Hope this helps and which side do you play usually.
