How can ships' ship's boats ship boats while shipping boats in a BOAT?

I won't insult anyone by thinking I need to explain the difference between a ship and a boat.

..now they're tubes carried by Poles..

<<It seems if I go into any local fastener specialist shop and ask for 3/8 UNF by 3 inch hex-head machine set screws, the counterman will invariably come back with bolts; that is the thread does not extend all the way up the shank to the head.>>

I bought a box of 6" reissner wood screws recebtly. I know they're screws 'cos they have pointy tips. But they are only threaded for half the shank. But if I buy machine screws then someone has always cut the pointy tip off. I think they make dog-point setscrews out of those spare tips.

Bazyle - have you been at the cooking sherry again ?

Regarding the definition of a BOAT

I'm waiting for the traffic announcement;

The M25 is blocked due to a shed load of shedloads of sheds.

In days of sail when a ship was just one configuration of sails and masts there was a clear difference, nowadays "'A boat is what you get into when the ship sinks."

I did an ambiguity! I was trying to say "In the US a tube is what the UK would call a valve, short for thermionic valve."

I'm easily confused:

Q. Which way does a clock turn?

A. It turns anti-clockwise if you are the clock.

I was told by an old submarine commander that submarines are boats and ships are targets......

Our local junkie always seems to have a straw stuffed up his nose. Never seen him with a tube!!!

And on subs, the pointy end goes at the back.

Tube is a hollow structural member of any shape or section.. Because it is used in construction, its most important dimensions are the external dimension, and the wall thickness as an indicator of structural strength.

Pipe is used to convey liquids or gasses.and because of this use, the only important dimension is the internal size, which gives an indication of the carrying capacity of the pipe, and the wall thickness, which gives and indication of the internal pressure the pipe will withstand.

Whilst pipe and tube are in a sense interchangeable terms in conversational English, in engineering the use of the term"pipe" for a hollow structural member, and tube for something that carries a liquid or gas, used to result in a thick ear for the errant trainee or apprentice.

Wanders off mumbling under breath about falling standards and the kids of today etc etc...................................

A very short thick walled tube is a washer

You have clearly never used copper pipe for plumbing where ( for instance) you have table X,Y or underground ( think that is it - its been a long time) all with different wall thickness but the same external diameter to suit a standard copper fitting. Changing to wavin flow plastic pipe the outside diam is kept at the same outer dimension as equivalent copper ( ie 15mm etc) but the wall thickness is greater

So that blows your theory out the water

But as the Monty Python team said ", try telling kids of today that-- they will never believe you !!!!"

In the construction industry we would not call that tube but either RHS ( round hollow section) or SHS (square hollow section ) etc etc -we certainly would not call it tube in the context you suggest

I cannot recall ever using  the term "square tube" in the construction of structural units. Although I admit we would refer to "tubular structures" in context of describing components in  lattice roofs etc made from hollow sections

I must remember when next I go to buy some new fluorescent pipes to call them tubes!
