The two pieces of evidence from the passage that best support the idea that Harborough does not consider the dangers that may be hiding in the ocean are:
- “The sea was, in a sense, absolutely smooth . . .”
- “The surface of that ground-swell was without a wrinkle, polished and glossy like lacquer . . .”
These selections illustrate Harborough's perception of the sea as calm and undangerous, highlighting a lack of awareness about potential dangers beneath the seemingly tranquil surface.
