Step two:
To ready the mast for the rig I mounted the spinnaker bale about half way between the shroud attachment point and the top of the mast. This may be a little high but my mast appears to handle it okay even up to 25mph wind as long as you keep the mainsheet tight to provide support for the mast.
Above the bale I mounted a block which the halyard runs up through and then back under the bale.

That is really all there is to the mast setup, it was simple enough. depending on the spin you may have to adjust the hoist height but you can change that or the pole height. Both can cause problems so be careful.
