I've got an even easier 1 step system.......Don't be affraid to ask anybody near by to help. It's often better if they are female when you ask for help errecting your mast. Good taste in this respect will pay dividends and will also prevent you from being arrested. Double checking that they aren't accompained by a 'partner' is also useful. If you're still convinced on doing it single handed then the use of shackles, chains, ropes and even trailers is fine by me.
(Firday night humour I hope)
Seriously: I prefer the asking for help rather than crunching a mast or hurting myself.
