The article says the Olympic team was selected from two events: ISAF Worlds in Santander, and the event in Miami. The Development team (USSDT) was selected only from their results in Miami. None of the teams had a "great" showing in Miami, that's for sure. Really tough for folks like JC with so much time invested.
Here is the team for the Nacra 17 (Mixed Two-Person Multihull):
Michael Easton (Bedford, Mass.) and Katie Pettibone (Port Huron, Mich.)
Sarah Newberry (Miami, Fla.) and Matthew Whitehead (Panama City, Fla.)
USSDT: Jeremy Wilmot (Newport, R.I.) and Louisa Chafee (Warwick, R.I.)
All of these folks have obviously spent time, money and effort preparing as well, and deserve our full support.
