Question

We had beached the boat and stepped out on the recently cleared spit of land.

Answer 1

Returned the boat to its harbor

Answer 2

False, it is "Stopped or parked the boat" returning the boat to the harbor doesn't fit the context no'r does anchoring it to the shore.When you read a story you will sometimes hear something along the lines of "A ship wreck was beached" thus supporting this answer.
