Our reading
An editorial interpretation.
The speaker firmly rejects a boating accident as the explanation for what has happened. The brief exclamation challenges that account without naming the actual cause. Its force comes from certainty: whatever others may think, the speaker insists that an ordinary accident on the water does not explain it.
