Good luck Phil & Sarah.
High hopes for the Ent at that location. Dynamically reacting well to big shifts, gusts & lulls will be key. So hopefully a hiking, non trap, non spin boat will be favoured for you and hopefully the Ent is light enough with your featherweights to accel well in the gusts.
Potentially deduct 2 forces of wind due to the buildings? Deduct less if it is blowing straight down the length.
Dont forget to mention Cherubs in your speach.
