Now How Do I Get My Boat Out?

My slip has been ruined forever. The Golden Gate Yacht Club has decided to put in a piling for a new dock off their deck making getting into and out of my slip less appealling. This unannounced barge was a shock as I pulled up. They left me just enough wiggle room to sneak out the back, but if a boat decided to tie up to the guest dock, I'd be screwed. Time to see the harbormaster.
