I have seen enough masts dropped to steer clear of anyone hoisting it up, no matter how firm their grip appears.
The thought of the average sailor telekineticaly stepping their mast, well, the slightest distraction, and crash!
"Wanna Beer" (crash) short shorts (crash)bikini(crash) "What's your sail number?" (crash) now let's think where the shroud pin is? (crash)
I think the increased liability would exceed the advantage of not holding the mast as you hoist it into the power line...?
