I have been reading the EIR and it will take a while to fully digest.

The study basically assumes that loss in wind speed must exceed 10% at primary
windsurfing launch and transit areas to be significant and then concludes that
speed loss is at a maximum of 10% and less than 10% in many areas.

It seems like the wind tunnel study has 105 foot tall buildings putting up
wind shadows not all that much bigger than the existing buildings put up in
some scenarios. Does anyone know how high and how high above the waterline the
existing buildings are?

The big issues will be:

1) Is their methodology correct

2) Is a 10% loss (or more?) significant or not? It seems like a 10% in wind
speed has about a 50/50 chance of forcing one to rig up to get out since we
tend to re-rig to a new sail size for each 20% change in wind speed.
