If it is not possible you want to tie it up, with extra lines and
spring lines, and keep it off of the dock.

The "keep it off the dock" is a real important consideration. Even in a fairly
minor "near miss" you can end up with an extra 6 foot of tide. I usually pull
my boat out of the dock and tie it off the end of the dock, well clear. There
are some outlying piles and a tree that I use for this. This way I don't have
to worry about the boat coming out the roof of my lift and/or finding it
sitting on the pier.
