Looks like the bend is all between the spreaders and the mast foot. Like Ross and others, I believe that if ya anchor it with a tree or something really strong just below the spreaders and opposite anchor at the apex of the bend… then carefully apply pressure to the mast foot, ya can straighten it..Use something like a big pad to spread the load.. The mast will want to twist so it will have to be really secure from rotating on axis.. Pull some and check and eyeball what is happening.. ya may have to move the pull point and anchor points as you work it to get it straight. The mast will work harden, as Donalex says, so you pretty much have one shot at getting it right (I agree with no heat).. be very gentle but firm, and slowly approach the “straight” shape so ya don’t overbend. Good luck with it.. It took only 300 pounds or so of snow (Not shrink wrap, right?) to do that so it is not going to take a lot of force to straighten it..You might even be able to support it at the foot and spreaders and, using sets of two concrete blocks tied together, simulate the snow weight (in the opposite direction) by starting at the supports with a set and placing/moving additional sets toward the apex of the bend. Make sure the blocks hit the ground before the mast gets bent in the opposite direction. Because the load in the upright mast there is mostly compression while sailing, the mast should be really straight to avoid a collapse.. I mean maybe an inch to an inch-and-a-half max over the piece from the spreaders to the foot. (ya ought to be able to get it better than that).. That mast is deck stepped so pulling on the stays won’t cure it..
