Chasing the goal of 20 knots in a Laser 2 - Day 1

I am pretty sure a Laser 2 can do 20 knots! Laser 2 with a custom spinnaker, sporting a total of 25 sqft in downwind sail area plus 25+ knots of wind should is scary fast!! But how fast?!?!? This is the first windy day since buying a Locosys GW-60 GPS watch. Not exactly nuking wind but still hit 16.4 knots! I have definitely had faster kite rides before. Just need another big wind day to keep trying for the two O.
