The are sailing in the bay, course Echo. There is a chart in the SIs if you want to calculate the distance from their launch site to their course circle.
I couldn't find anything about the RET.
There is a protest schedule listing the DPI as a result of a protest lodged by RC. No other details, but no shortage of possibilities based on NOR and SIs.
Edit: The ISAF race management policy document is also posted on the notice board. They cannot start in winds over 25 knots (5-minute average), but will not abandon if the wind goes higher unless they determine it to be unsafe. There is a lot of interesting stuff in there, including the fact that if the RC determines that they missed an OCS boat, the race cannot continue. This is in direct conflict with what I have been taught by multiple IROs, FWIW...
