Hi Barry
The statue race suggests the opposite. several of the 6.0's with NE chutes seem to finish ahead of the I 20's boat for boat..
Not sure what that means either.
Further support for a small chute comes from the texel ratings.
The Texel rating for a 6.0 would be close to 91 or 92 with a 28 sq meter chute.
the US 120 would measure in at 94
While the Tornado would measure in at 95 along with a euro I20 (smaller main)
I don't know that I believe these numbers but there they are.
In your opinion, to make the boats level what size chute is required to make the boats essentially level rated around the buoys (assuming the snuffer is not a factor in the waves)
Trying to move the ball here.
