OK, single handed raising of the mast on my Stealth (did this just yesterday):

1. line boat up with trailer arranged behind to be able to use mast support at around hounds position

2. connect all wires except forestay (obviously)

3. hull is arranged so that sterns are sitting on protectors whilst bows are slightly raised by virtue of sitting on launching trolley (I also shove the rolled up cover in front of the trolley wheels to prevent it moving)

4. run a line from the forestay, through the bridle shackle and back to the mast base (I loop it throught the diamonds so it stays there)

5. with the mast firmly on the mast ball and having checked that all wires are clear of getting caught, I walk the mast up to vertical

6. while holding the mast up with one hand I pull in on the line from the bridle and, when tight, tie it SECURELY to the diamond wire

7. quickly move forward to the bridle, reeve the forestay lashing through the bridle shackle and tighten up

8. set up the rigging at your leisure......

I've found it helps if there is some breeze and you can rig with the wind behind you
