Backing Up in a Slip ( Engineless )

[otherthan]

can it be mastered?
I read of someone terminating a circumnavigation who backed his ship into a slip while useing his sail only...id love to hear about this (or better see a video)

You can reverse by backing both the jib and the main (can't really do successfully with a single sail) so that the force of the wind is in the forward facing side of each sail, pushing the boat backwards. Backing the jib is also a way to get out of irons. I've done the latter on a smallish boat, but never the former.
