The sailing season, when one might hope to venture forth with any degree of safety, was limited to some fifty days after the end of summer. Even under the best of conditions, the ancient mariners strove to keep land in sight at all times, making their way cautiously from headland to headland and drawing their vessels up on the beach at night.
