Yes, one of the reasons I upgraded from a 13' to the new 16 is because it will sail upwind with its dagger board and it is only 3.5Kg heavier than my old 13'.
Speeds I havent checked on this one but I think it does 7-8MPH in perfect conditions.
I need the Stabilizers even though they cause drag because I am on the Pacific coast and we get a good 15 knots every day, plus my bad back stops me leaning much.
One day I might attach the FINN AMA's and then I will prolly sell my AI2 as it is getting a bit heavy.
