Sling positioning
Hi,the main issue is to get the sling above the masts centre of gravity. Then you just loose everything with no slack in sling. There are big risk for injuries with mast operations if you are unexperienced so be careful and think everything twice before you do anything. There must be minimum 3 people to do the job. (one for crane, one to spring around to loose wires, one to steer the mast). Never let the mast hang free without somebody steering it! In our club are about 150 boats removing their masts before winter and the average time to remove the mast is about 30 minutes for experienced crews and about 90 minutes for unexperienced crews, I believe.
