Future Races (Marblehead-to-Halifax Ocean Race 2019 and later)

"Offshore" Safety at Sea (1 day) Seminar certificates dated after 2017 will not be accepted in future Marblehead-to-Halifax Ocean Races.

After 2017, certificates will have to be earned at a US Sailing sanctioned 2 day "Offshore Seminar with Hands-on Training" session. The 2016 and earlier Safety at Sea certificates will be honored until their 5 year expiry date has been reached.

In-date World Sailing/ISAF certificates have always been accepted and are strongly recommended.
