If you are trying to heave to withthe jib and main, how can you reef the main after you are succesful?[/QUOTE
The backed jib and the rudder are what allow me to heave to. Then I set the traveler over to take pressure off the mainsail. Sometimes it's necessary to ease the mainsheet. Basically the boom pointing toward the wind..so the main is in irons..then you can lower the main to set the new tack and clew.
The main doesn't need to flog around..just needs enough pressure off to ease the halyard.
