We were on charter in July a number of years ago on a Moorings 5800. We were at Leverick. A disturbance was going to go through. It wasn't forecast to be too bad - I don't think it was even a tropical storm or maybe just barely.. We were told we were fine where we were and we just did extra lines..etc to be sure we were very secured. Dock staff at Leverick was great helping us get secured. Had it been worst it is my understanding they'd call you back to base although I'm not sure what the threshold is for that.
