If you aren't having any trouble lifting the mast, I highly recommend the system I use. I simply attached my old lower block from the mainsheet to the trailer at the same angle as the forestay coming down. I then tie the sheet to the chainplate above the furling drum. After this, run it through the block and put the loose end on the tramp by your feet or loosely tie it to the diamond wires. Lift, cleat, get down and attach the bridles. Simple, easy, cheap and very effective. Reverse it for lowering the mast. I've used this method lots and never had a problem. As with any system, just make sure everything is set before you raise or lower.

I just bought an FX-1 and the previous owner had a setup using the traps to triangulate the rig and keep it square. He then used the winch to actually raise the mast. I hate it. The mast is more out of control using this method. I'm going to switch it to my setup on my 18.

Hope this helps and Happy Sailing!!
