DANIEL IS ROUSED by a rooster on the forecastledeck * that is growing certain it's not just imagining that light in the eastern sky. Unfortunately, the eastern sky is off to port this morning. Yesterday it was to starboard. Minerva has been sailing up and down the New England coast for the better part of a fortnight, trying to catch a wind that will decisively take her out into the deep water, or 'off soundings,' as they say. They are probably not more than fifty miles away from Boston.
