Does anyone know the true defintion of a 'ship'.
At what criteria does a craft stop being a boat to become a ship.
Purely asked out of interest and to improve my nautical knowledge. /forums/images/graemlins/smile.gif
Among sailing vessels, the distinction between ships and boats is that a ship is a square-rigged craft with at least three masts, and a boat isn't. With regard to motorized craft, a ship is a large vessel intended for oceangoing or at least deep-water transport, and a boat is anything else.
But that's too much to remember. Try this: 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, thay are also called boats.
I think the magic number we were given was 500 t. From that moment on the MCA makes your life "interesting". I don't know the thinking behind that number. I do think that at some point it will become obvious to MCA that modern yachts (boats not ships) are getting bigger, and that a fixed number is not the best definition.
Ditto - we carry a RIB and a sailing dinghy (alebit an inflatable one). The inflaty thing was used to great effect in Weymouth last summer winding up the raggies. That'll teach Chris_b4 to tell us he can sail anything...
