What does "seaworthy" mean? It means something that can survive being out on the sea. But "worthy" is a word with interesting connotation. It doesn't just hint at toughness, but also at a sort of rightness. The author, Linda Greenlaw, has taken a nine-year break from swordfish fishing. Then she returns to to it, captaining a broken-down boat. She's older and wiser now, but by the time the venture's over, there will be blood and arrests. Greenlaw suffers doubt: has she grown soft; is she still seaworthy? Fun story; fun in the sense of "Oh man I'm glad that didn't happen to me."
