Gday Chaps, great thread and plenty of good ideas to ponder, I regularly do the solo sailing thing and just have a couple of variances to whats already been said. Firstly for pinning the mast base I prefer to keep the mast located on the mast crutch behind the boat as its further aft than the beam itself, also I've cut a vee shaped rubber piece for padding of the crutch which doubles as a means of steadying the sideways wobble you get when pushing down the mast pin it at the base. I have all trap and side stay wires ready and layed out as per H2814D's instructions, but to keep the mast up after the lift I simply untie one end of a jib sheet (that normally terminates at the jib car), run it through the lower end of the forestay adjuster and then tie it to the forestay thimble, the other end of the jibsheet is already running through the cleat and the rope is at your feet ready for you to grab and tighten holding the mast up, the forestay thimble will rarely line up with its attachment hole straight away but can easily be manipulated into place for shackling.
Lastly I always solo step from the tramp as I feel the awkwardness of getting up to the tramp is harder than deadlifting with your back foot on the aft beam. Just remember good lifting technique is important.

Cheers Phil
