What Really Defines A Ship From A Boat?

Sat Feb 11, 2012 4:18 am

We all know that a boat is rather small and a ship is rather large in the prospective of size akin to the difference between a plant and a tree. We know that a ship can carry a boat and a boat can carry another boat as they often do but a boat cannot carry a ship. From the research that I have done I have not been able to get a defined answer. Lake going vessels in the Great Lakes are referred to as boats even those that exceed 1,000 feet in length and small rigging vessels like the Santa Maria which was and is in replica 70 feet long are considered ships so is their a true definition or does it vary from industry to industry.

That's because:

so is their a true definition

No, there is no legal difference between a "ship" and a "boat" for purposes of maritime law. The legal term is "seagoing vessel".

From my friend who has spent much of his life under the surface. Boats are vessels going under the surface. Ships are targets.

A boat is what you get into when the ship is sinking.

Depends on whether you are the Captain or a passenger.

If you're the Captain of the QM2, it's a ship and if you're a passenger it's a tub.

Boats are under the surface. Ships above.

http://en.wikipedia.org/wiki/Sorites_paradox

Quote:
The sorites paradox (from Ancient Greek: σωρείτης sōreitēs, meaning "heaped up") is a paradox that arises from vague predicates. The paradox of the heap is an example of this paradox which arises when one considers a heap of sand, from which grains are individually removed. Is it still a heap when only one grain remains? If not, when did it change from a heap to a non-heap?


 

I think there are only arbitrary definitions somewhere in the law. I would define a ship as a vessel that is commanded by a professional, very much like a 747 is an airliner, and a 172, this' a plane.

Technically the word "Ship" refers to a sailing rig with three or more masts, where all the masts are square-rigged, as opposed to a cutter, barque, schooner, sloop etc. That is the only formal definition that I'm aware of.

Yep, the COLREGS don't care what you call it, just size, how it is powered and what kind of special work it might do...

Quoting czbbflier (Reply 3):

Another version of this is a boat is something you can hoist up on the deck of your ship...


The US Coast Guard defines anything smaller than 65' as a 'boat', and anything 65' or longer a "cutter", harking back to the rig of the original vessels that sailed for the Revenue Cutter Service. Which gets crazy when you consider that Coast Guard Cutter EAGLE, America's tall ship, is a barque! If that doesn't hurt your head I don't know what would.

I´ve once heard the definition that a boat is run by mutual consent, while a ship has a master and a chain of command.

QI asked this question. It became quite clear that there is a very large grey area, but apparently within the Royal Navy, ships sail above the surface and boats below (as others have mentioned here). A submarine is certainly not a ship in most people's vernacular despite having a clear chain of command.

This might come from the German use of the word. The U-Boot/U-Boat was the submarine, and the Allies and the Germans called them, "U-Boote", "U-Boats" or simply "boats". (Why are there no "U-Schiffe" or "U-ships"?)

In German, we have "Boot" and "Schiff". The military meaning set aside, with "Boot" we designate things that are privately used (a rowing boat, a sail boat, a fishing boat). Then, with "Schiff" we mean mostly commercially used vessels, like fish trawlers, ferries, tankers and so on.

Is a 747 really an airliner if its privately owned and not flying a "line"? To me it would be a plane and not an airliner.

Possibly because the first military submarines in wider use during WW1 were quite small compared to the standard battleships of the day, with a crew of only about 20-30 men and a total length of less than 70 meters.

Even the most built German WW2 submarine, the type VIIc, was only 67 meters long, with a crew of 50 men.
