Maybe we should have bought radar for this trip and not a GPS. We knew we were two miles off the south coast of Iceland near Vestmannaeyjar, or the Westman Islands, but where were they? We could see nothing. It was 0200, and the midnight sun accentuated the diffuse, pearly quality of the fog. This fog was different from what we were used to in Ireland: Here, the moisture froze on contact with the boat. People said that May was too early to go north to Iceland, but Mithril, our 50-foot steel ketch, was well suited for the North Atlantic weather, and we wanted to make the most of the 24-hour daylight. The weather had been excellent for most of our five-day passage, with strong southeasterlies shoving us along.
