My wife's and my bike are near the middle. Mine is maroon and has the yellow pannier on it; my wife's bike is the the custom built blue bike next to it. Just be a gentle as you can, but ride it. My wife summed it up pretty well, "our bikes are just tools we take care of our tools but the are made to be used."
The deckhand loaded our bike along with a couple of dozen other bikes onto the ferry. It was either let him do it or not take the ferry.
