Apparently they do have different foil boards for different conditions. Just have to make the right call before putting the boat in the water for the day's racing

Yes the sail trimming and board controls are done with hydraulics, the pressure is being maintained by the grinders/ peddlers. I do find the constant action in the pit a bit unusual and a little distracting.
The peddlers less so, plus they can put more power into the system than the conventional grinders. The upright sitting grinders with shoulders and arms flailing away surely creat more windage drag too. Again the Kiwi ingenuity coming thru. Do you notice a familure accent aboard most of the boats, yep that's the Kiwis they are everywhere in the sailing world.

Looking at the sail trim angles is revealing, even going down wind their boat speed brings the wind so far forward that the sails are way in closer to the centerline than imaginable. Sure makes jibing easier.

I'm really enjoying watching these amazing boats and crews. So much innovation at play and the crews are refining their boat handling as the races unfold.
The high speed make even little mistakes a big deal in relative position on the course, quite exciting.
