be at sea(redirected from are at sea)
be at sea
1. To literally sail on the sea in a boat or ship. A: "Is your mother at sea yet?" B: "Yes, her cruise lasts several weeks."
2. To be puzzled, perplexed, or completely confused (about a subject or some task at hand). I tried to do well in this class, but I've been at sea since we started.
