Gothenburg claimed that it was a much shorter passage for the oversees entries (about 525 nm) than it was to Stockholm. Stockholm however got the sailing program because of then all Olympic events should be in the same vicinity. As specific location Nynäshamn, about 60 km from Stockholm was chosen.
