Agree with Robi ... I've never stepped with help. (although I will begin looking around for *help* <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" /> per MarkP's suggestion )

I find it best to first start with mast in horizontal position as if just lowered (without rotation). Rig standing rigging (traps, side stays and spin halyard). Be sure everything will be clear. I've installed a stainless eye hook on the trailer mast stand. I run my spi' halyard thru this and back thru the jib blocks. The other end of the spi' halyard I run thru the mast spreaders and tie to the base of the mast (mast rotator). Be sure these two ends are secure as this will support the mast once raised.

rotate mast 180 (so that sail track is up). Install pin at base. (Note: I've got a mast stand I use behind my trailer made from PVC. Effectively a tripod--I'll attach a photo next time I'm at my boat--this helps keep the mast from "levering" off the rear beam).

Once raised I tigten the spi' halyard that was run thru the jib block. Follow Robi's instructions from there...

Reverse for lowering mast.

NOTE: be sure to keep the mast at 180 degrees all the way up (or all the way down)....If you allow the mast to twist before fully erect you'll bend the stainless fittings at the base of the mast (and front cross beam) and need to get them straigtened (pain in the A**) or replace them).
