If one were thinking about it. I guess you should have all the lines, blocks, shackles, etc. hooked-up to the emergency tiller and preset to be deployed. You'd have two sets of large "baggies" which would allow you to instert the tiller, and then "clip-on" the necessary devices in short order
Then you'd basically pull the the thing out, and just get it set-up.
I will CONFESS, I've never tryed to hook mine up. Maybe this Winter, I'll pull it out and see what would really be involved. (I guess after 14 good years without and issue, prevention would be the best policy.)
