This is how we put the mast up on my previous boat, a Hurley 22.
Built yourself a mast rest out of old timber to take the weight of the horizontal mast from a deck or cockpit sole.
Recruit at least two volunteers.
Reverse the boat onto a pontoon. This makes it easier for volunteer 1 to start the lift. Attach all stays and shrouds. The bottom of the backstay should be attached to the opened out bottlescrew. With the weight of the mast on your rest put the foot into the tabernacle and push through the top bolt.
You shackle a line to the deck end of the forestay and take a turn round a bow cleat. This is a safety check... take up slack as the mast goes up.
Volunteer 1 starts to walk forward raising the mast. Volunteer takes over when 1 can't go any further or the mast is too high for him. Repeat until the mast is vertical, then the spare volunteer attaches the shrouds first, as you attach the forestay. Put in the bottom tabernacle bolt and tighten up the backstay, then the shrouds.
In reality a third volunteer is handy to do any running and free rigging when it hitches something that gets in the way, like pushpits.
Go to pub and reward volunteers.
