Hello,

I do have quite a lot of tracks from my blade, and also some tracks of other Blade's.
Upwind in good conditions is about 11 knots. Range would be 10-13 knots but 13 knots is only possible (at least for me) if there is some current involved or when overstanding the layline so not really upwind anymore.
Downwind between 15 and 18 knots. 18 only in relative smooth water, and still is an exception. All tracks 2-up.
Sure i've seen more speed on the gps or later on a track, but those were defintely "spikes". Am curious if anyone (on an F16) could hit 20 knots for say 30 seconds or more..
