Not anything measureable. Probably nobody's bothered to really figure it out, since the difference couldn't be seen on a wavy sea with a microscope.
But I'm going to make a couple assumptions and make a little calculation based on those.
There are 2 million boats/ships on the seas, average 20 feet long, 5 feet wide, 3 feet deep = about 130 cubic feet.
The average depth the entire way is 3500 feet.
There are 120 million square miles of ocean. (somewhere around there)
The water level is perfectly constant, no waves or whatever.
Convert square miles to square feet, multiplied by depth to find cubic feet of water
Then subtract 2 million x 130, then divide by the original water volume to get a percentage
Multiply the percentage by 3500, then subtract that from 3500 to get the change.
It was tiny- about 8 x 10^-8 inches- meaning 80 billionths of an inch. Convert to recognizable metric, and it's 197 nanometers. Most people can only see objects as small as 100,000 nanometers with the naked eye.

It wouldn't. All the the ships in the world don't represent enough volume to make any kind of a difference.

A whopping 2 nanometers.

Not really sure but probably alot of water.

not noticable.
