The Marion to Bermuda Cruising Yacht Race is a biennial yacht race held in odd-numbered years, from Marion, Massachusetts to the island of Bermuda, a distance of 645 nautical miles (1,195 km). The most recent race was held starting June 9, 2017. Due to the blue-water sailing involved, each vessel is required to have a portion of its crew attend a recent Safety at Sea seminar from US Sailing. The organizers of this race and of the Marblehead to Halifax Ocean Race cooperate to sponsor a Safety at Sea Symposium and Practical Training held in the spring before each race.
