Hi Kenwood,

Have you had a chance to try my backwards mast stepping idea?

The forward lower side stays would stay connected and the forestay + roller furler would remain tied off to the mast.  The backward rotation of the mast would be stopped by the forward lower side stays .  Port/starboard tipping of the masthead during mast stepping would be limited by the upper side stays.  Once the mast was raised, I would attach the back stays, then the forestay, and finally the forward lower side stays.  Then, you could disconnect the halyard and remove the gin pole.  I can picture the process working slick as a whistle.  So, next question, does the bottom of the gin pole fit into the table socket in the cockpit and are the guy lines sized to secure the gin pole in an upright position?
