bridge sign, Naut. a sign on a pier or quay to show where the bridge of a certain vessel should be when the vessel is moored.
We moored ourselves. The journey over water had been long and now we edged in from the sea. Places we knew before only by faint lines on a map were now vivid to us. But there was something even more thrilling than the adventure: the arriving, safely, at the quay. We pulled in to the space marked by the sign and anchored. Home.
