Wow Mat, That's an ingenious way of doing it.
I've sailed solo, on 18 and 20 ft cats, rigged them myself, etc. But I always got a passer-by to do the tip of the mast thing while I lifted it, stern to the wind so I could even do the forestay.
But, if you don't have anybody willing, or anybody, then I'm going to remeber your methods, just in case.
