If you do end up in irons, you can simply wait until the wind and current pushes you one way or the other and you’re able to fill your sails again. You can also speed things along by turning the rudder hard to one side. The wind will tend to slowly push the boat backwards and turn you in the opposite direction as you’d move if you had headway. The process can be helped along further by holding the jib on the opposite side of the boat.
