I’ll try,Jem…tho’ I spex I’ll be shouted down. #sigh#
Y’see;the English word “ship” derives etymologically from a Germanic word,“Schiff” and the Latin word “navis”, which is closely related in meaning,is feminine. Ergo;when ‘schiff’ is used,it’s become ‘ship’ to English speakers and is invariably used in the feminine form-although it has oft been said by seafarers of olden times,that one of the reasons is that ‘she’ [the ship] took a lot of careful handling and attentive maintenance,to get the best out of ‘her’.
However,BECAUSE certain parties took umbrage at the ‘she’ references when speaking of seagoing vessels,since 2002,Lloyds has taken to referring to all-and-any vessel insured by them as ‘it’.
Yup - that’s true. Sad,innit.
If I got the chance to swish my roller around ‘HER’ bottom or ‘IT’S’ bottom,my stiff little roller would be a blur as it caressed HER bottom.
ONE
SHIPS TONNAGE (ie WEIGHT OF SHIP)
Thus, Oasis of the Seas at 220,000 gross tons is considered a bigger cruise ship than Navigator of the Seas at 137,000 gross tons. Because the word “tons” is used in connection with this measurement, people often think that the gross tonnage is the weight of the ship.
WTF are they talking about, surely the weight is the weight.
TWO
I have forgotten the 2nd question, I’ll post it later
PUG "animal, vegetable or mineral round.
I remember the questions now, Actually TWO more.
ONE
How do garden centre calculate the volume of bagged composts, currently in litres, when we all knows that LITRES is LIQUID volume, not solid material
THREE
How do you calculate the volume of liquid in a 6ft diameter fishbowl? (sphere)
Number three is easy, you fill the Fishbowl with water, then decant it into a measuring jug, and take the reading off the side, then if you want, make a note of that reading and empty the jug, you can then half fill the Fishbowl, add a Goldfish, then fill the bowl again, the remove the fish into another receptacle that has water in, pour the content of the Fishbowl back into the measuring jug, and minus this figure off the first figure, thus you will have the Liquid volume of the fish, which can be converted to cubic millimetres if desired.
oi oi spittie hold ya orses - where on earth did robert say there was a fish in the bowl ?? = catch question there spittie lad - back to ya concrete saw and ya patio!!
I thought the mass quoted is the mass of water displaced by the boat, not its actual mass.
So, you take a lump of steel weighing 1 tonne, and drop it in water. It will sink.
If you take the same lump of steel and roll it and beat it until it is boat shaped and drop it in water, it should float, displacing a mass of water.
If you change the shape of the lump of the steel, it still weighs 1 tonne, will still float, but will sit higher or lower in the water depending on it’s shape.
The mass of water displaced will therefore be different, even though the “weight” of the ship is still 1 tonne.
I’m guessing there is a standard density of water when quoting tonnage since the amount displaced will vary with temperature and mineral (salt) content.
This is also why there is more than one Plimsoll Line on a ship. Loading a ship in cold dense sea water could cause it to sink in less dense warm tropical fresh water because the vessel becomes less buoyant.
Measuring the displacement of a ship could be done using the same goldfish bowl method already explained.
Put the boat in a dock full of water, and measure the volume of how much spills out. Knowing the water density then allows the volume to be converted to mass.
As a retired aerospace enginerd, I can conform that everything I have said is pure guesswork.
