Sailing (and especially racing) at night sure is different. Many years ago I was crewing on a Beneteau First 42. We were returning to San Francisco Bay under spinnaker after rounding the Farallones. It was pitch black, foggy and cold. We were an experienced, fairly well-knit crew, but we screwed up anyway. The rudimentary GPS was set for Point Bonita, outside the Golden Gate. Sure enough, the lighthouse appeared suddenly out of the fog, and we were among the rocks at the base of the headland! The keel took a solid hit. We quickly drove up, but struck again before getting into clear water. It was probably the closest I ever came to being a sailing casualty. Still gives me the willies when I think about it.
