I have have roller furled genoa with extrusion (CDI FF2) on my 26 foot trailer sailor. Stepping and unstepping the mast is not a problem. You just have to control the unattached drum end of the forestay during the process. I simply use the furler control line pulling forward to keep the end from flopping around. And as Kermie says, lash it to the mast when it's down.

I'm not sure what Dickens are, but I think they may be important and I sure as hell don't want them scared out of me.......Izzy
