I don't like it because it can't be done single handed. It would be interesting to see the take down sequence..... That's quite an angle for the lifting line to the spreader loop... looks like the crew might have to do the lifting.What is your opinion regarding this mast raising idea? Did they rig this up themselves with a pvc type material or is it common sailboat accessory??

For the under 27 foot boat, I'd much prefer a hinged tabernacle base with a moving gin pole or A frame system for the actuation. A crutch to get the mast above horizontal and a winch or tackle system for the raising and lowering completes the package.
Check this system out.....solid, safe... easy up and down.... very good demonstration:
