Why is boat at sea evidence for a round earth?

A boat at sea, alone, does not prove that is earth is round. However, boats can be used to prove that earth is round. This is because if the earth was flat, eventually a boat would sail to the end of earth and fall off the edge. This has never happened, so it can be inferred that the earth is round. Also, a boat can sail all the way around the world and end up right where it started, which proves that the earth is round.
