I though when you approach the mob you should in iron.
That's a no-no. If in irons, the luffing sheets and boom make movement about the boat while focusing on the person in the water very hazardous. You risk potentially more serious injury to persons IN the boat than perhaps those experienced by the person in the water. You definitely want the sails luffing off to leeward and the MOB to windward...On a boat with an overlapping jib, furling the jib during the approach is a good step.I though when you approach the mob you should in iron.
