The Whitbread 60 (W60) or Volvo Ocean 60 (VO60) was a box rule that was devised to govern the 10 smaller yachts which took part the 1993–94 Whitbread Round the World Race. They were raced with such success that the following race was restricted to the Whitbread 60 class only. The class was used for the last time in the 2001–02 Volvo Ocean Race, after which it was replaced by the sophisticated, canting keel Volvo Open 70 box rule.
