This was discussed in detail further up the thread, but basically the Nacra 17 gets 20 slots in the Olympic regatta. One of those spots goes to the host, so 19 are available. About half of those spots were allocated to nations based on finish position at the 2014 words. I believe 3 more spots are available at the 2015 worlds. The final spots will be available at a series of regional events (likely 2016 OCR).

If the US does not secure on of these spots, there will not be a US Nacra 17 representative in Brazil.
