J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Pulling a J30 mast

I need to pull the mast on my J30. Don't have a crane but was going to attach a pully to the cross bar of a Travellift. I figured just below the spreaders. I think the purchase is 6:1, 4 pulleys at one end and 3 at the other end. How heavy is the mast. Any other tips or tricks
