If you removed all ships, boats and vessels out of all the seas and rivers how much would the sea level drop by?

Just under one and a quarter millimetres, about one twentieth of an inch.
Here's the calculation...
The oceans cover a little over 70% of the Earth's surface, 362 million square kilometres, and have an average depth of 3710 metres. The volume is approx 1.343 pentillion cubic metres
According to Encyclopedia Britannica the total gross tons of all shipping is 436,026,858. The average density of the seas and oceans is 1.035 grams per cubic centimetre. The total displacement of all shipping is a little over 421 billion cubic metres.
Dividing the volume of water in the seas and oceans by the gross tonnage of all shipping gives a figure of just over 3 million - in other words, shipping displaces one three millionth of the volume of the oceans.
Divide the average depth of the oceans by the proportion displaced gives a figure of 0.001164, multiply by 1000 to convert to millimetres to get the answer - 1.164 millimetres.
To put it into context, the oceans are rising by an average 3mm a year. If you removed all vessels it would take about 4 months for water levels to return to their previous state.

Everyone loves magical Trevor,
The answers he gives are ever so clever,
Look at him now dissapearing a cow,
where is the cow it dissapeared somehow?
YOU ARE ALL MAKING A TERRIBLE MISTAKE!
Ice floats because it weighs less than the mass of water it dissplaces however the Ice on Antarctica is not floating and is sitting on a landmass if that stuff melted completely we might be foooked,
However this is not the problem.........the real issue is the cooling of the sea of magma!
The worlds water level is remaining at its level but the land is sinking as the magma cools. This gives the impression of rising sea levels. With less oil and gass fueling the magma through plate techtonics each year this problem will become progressively worse.
Humans are just a virus in shoes.

The answer to Global Warming is to stop putting out gas that will make the temperature of the earth increase.
Carbon Dioxide and Carbon Monoxide are bad, Methane is many times worse and Water Vapor will finish us off, when the oceans emit enough of it. There are other gases.

Your solution is too much ,especially when there is not a problem. STOP Ice is less dense than water is the reason it floats . So it will occupy 1/5 less space than the ice so if it did happen the oceans would go down not up.

Impreceptiblly.
More ice breaks break free every year from Greenland and Antarctica than the volume of water displaced by our shipping vessels.

Very little. But more than the rise caused from the COMPLETE melting of the Arctic ice cap (which is zero, by the way).

The answer is get out your sun tan lotion, lemonade, and sun glasses!!!! WOOHOO!!!!! yeah. Global Warming is not going to be bad at all. And humans aren't causing it, either.

If only it is that simple to make the sea level drop by this kinda way.....................

less than 1mm, if all the water in over head tanks and water stored in coke are released.....................
