A boat is a small vessel for travelling on water. Sailors have a rough rule for the line: a ship can carry a boat, a boat cannot carry a ship. Size is the usual test, though submarines are traditionally called boats no matter how large, a habit left over from the small early submersibles. *In the same boat* means sharing a difficulty, and *rock the boat* means to disturb a settled arrangement.
- A small vessel. *A rowing boat.*
- In the same boat — sharing trouble. *We are in the same boat.*
- Rock the boat — cause upset. *Do not rock the boat.*
- Miss the boat — miss a chance. *He missed the boat.*

What is the difference between a boat and a ship?
The traditional rule is that a ship can carry a boat but a boat cannot carry a ship. Submarines are an exception and are always called boats.
Where does push the boat out come from?
From the effort of launching a beached boat, which needed several people, and so came to mean a generous or expansive gesture.
