We have reached our highest speed on a reach too. That means a one up can never beat the max speed of a 2 up boat as a 2 up boat has more weight to reach the max speed.

I haven't checked my Como tracks yet as there the wind was very stable and the water flat and we might come close to our top reach which was at sea.

Anyway, we have 19 knots as top over 10 sec.
Second best over 10 sec is 18.4 and the others are close to that. Even 10 sec tracks will still show some spikes I think....
