At what point does a "boat" become a "ship"?
Answers:
Konrad is pretty close.
Ships have to be big enough to carry boats, and boats have to be small enough to be carried by ships.
There are exceptions, of course. Many commercial fishing craft, for example, are sizable oceangoing vessels, yet they're almost invariably called boats. Similarly for submarines, built by General Dynamics' Electric Boat Division. The Great Lakes are pretty deep, and one sees certain large vessels on them that to all appearances are ships, but in fact said vessels are commonly called ore boats. However, these exceptions mar the classic purity of the answer above, so we'll pay them no mind.
It has also been said that "if it sails on fresh water (lakes and rivers), it's a boat; if it sails on salt water (oceans or seas), it's a ship." But there are exceptions to everything.

I'd say ships are for commercial purposes and boats are for recreational/personal use.
A ship is a ship as soon as it's big enough to carry a boat.
A vessel is a ship once it becomes large enough to carry a boat. However, a ship is defined as a large boat so a ship is a ship and a boat. Unless the boat miraculously grows it will only ever be a boat.
After you've spent three times the amount of money you had budgeted for the "boat".
At the point you start writing it.
A boat becomes a ship when it has space for cargo.
Generally it is understood that if a vessel can carry a boat, it is defined as a ship. An example being a ferry carrying lifeboats. So 'Ships' can carry 'Boats' but 'Boats' cannot carry 'Ships'!
a boat is any sea going (in this case) vessel however powered.
my 42 foot yatcht is a boat AND it carries a boat in the form of a tender. it doesn't make my boat a ship.
ships are big boats like mugs are big cups. you know one when you see one :-)
The answer to your to your question is complex::
1) the definition of a boat is, As long as it ( the boat) can be placed aboard another boat, it is considered to be a boat. According to USCG Terminology, any boat longer than 65 feet is considered a Cutter, and still classified a " boat ".
A ship can carry one or more boats.
I asked this question and got the same silly answer of 'A ship can carry a boat' So can a very large boat fit on a very small ship?
