Will the ship sink further into the seawater than if it was in fresh water?

The ship will sink slightly. Salt water is denser there for heavy objects will float more in it. When the ship goes back to fresh water the density decreases and the ship lowers again.
This link gives extra information and some simple experiments for you to try at home.

When the increase in the salinity of seawater result in an increase or decrease in density?
If you compare the density of sea water, and then compared the extremely salty Dead Sea, you will find that the more salt in the water, the higher is the density. Which is why you can float on the Dead Sea while reading a newspaper (which I once saw demonstrated in a documentary). Also, a ship will float lower on a fresh water lake, and float higher on salt water.
Why did density have to do with salt and egg float?
Put an egg in fresh water and it will sink. Put the egg in heavily salted water and it will float near the surface. This is because the salt makes the water more dense and able to support more weight. The same goes for a ship. A ship will settle lower in fresh water and the same ship will float higher in the oceans.
What is the definition of water displacement?
If you were to submerge a cube that is 1MX1MX1M in water you would "displace" or move one cubic meter of water. The cube would be where water was, so it is said that the water was displaced. One measure of a ship is how much water is displaced when the ship floats. Something that is floating will displace its own weight in water.Water displacement moes the water so you can tell the volume of an object. Also... Displacement is a measure of mass as in a ship's displacement. A ship will displace the amount of water equal to it's mass or weight. The amount of water displaced, by volume, can vary depending on whether the ship is in salt water or fresh water. A ship will displace less water in the ocean than it will, let's say in a river. A gallon (US) of sea water weighs about 8.55lbs (3.88kg), while a gallon (US) weighs about 8.35lbs (3.79kg). If the same ship were in a river or lake of fresh water it would sit lower in the fresh water then it would in the ocean. Ocean's water, being heaver, is then more buoyant.
Compared with an empty ship would a ship loaded with cargo of foam insulation sink deeper into water or rise in water?
A ship that weighs 1,000 pounds displaces 1,000 pounds of water. Basically you are making a hole in the water that would take 1,000 pounds of water to fill, if it was Jell-o you could see the hole when you took the ship out. If you add 100 pounds of weight to the ship, be it feathers, foam, or lead, it will sink deeper and displace 100 more pounds of water.
What is more dense than water but floats on water?
a ship
Why does a ship entering from fresh water to sea water sinks more?
You have it backwards. A ship floats higher in seawater than freshwater. This is because the dissolved salt makes seawater denser. due to the lack of salt content in fresh water. the salinity of ocean water makes it more dense, allowing the boat to sit higher in the water.
How does moving from saltwater to freshwater effect a ship?
A ship will ride higher in salt water than it will in fresh water. Archimedes principle states that an object floatingin a liquid will displace an amount of liquid equal to it's own weight. Salt water is more dense than fresh water. Seawater weighs about 1025 kg·m-3 while fresh water weighs 1000 kg·m-3. Since the seawater is 2.5% heavier, a boat will sit higher when in it than when it is in fresh water
Does seawater and freashwater change the way a ship sails?
Yes, but not much. A ship is more buoyant in seawater, and thus less of the hull is in the water (thus less resistance).
Do ships in the general lakes need more or less ballast than ocean-going ships?
Ships need more ballast in the ocean because the salt helps to keep them a float.What we know is that salt water is about 3% more dense than fresh water and that ships use the water they are floating in for ballast.Say an ocean ship needs 10 tonnes of ballast to get to it's stable water line. The volume of 10 tonnes of seawater would equal 9.7m3.That same ship will float slightly lower in fresh water since fresh water is less dense. It will need 3% less ballast weight (9.7 tonnes) to get to the same stable water line in fresh water. The volume of 9.7 tonnes of fresh water would equal 9.7 m3.So, the ship in the ocean requires 3% more ballast weight than the ship in fresh water, but the ballast volume is the same in both cases.
Why do you have high and low sea water suction?
When the ship is at the port, the water is shallow therefore we use high seawater suction. If the low seawater suction was used instead, impurities such as sand would be sucked into the system..
Will the ship sink further in fresh water or sea water?
Fresh water. Salt water is denser and therefore makes things more boyant. Ships have marks painted on the side of their hull, usually welded lines and then painted over, that show their load limits in salt and fresh water. These lines are known as Plimsol lines or International Load Lines.
Where does a cruise ship get fresh water?
They get it from a desalination plant onboard a mighty fine ship.
Can ocean-going ships float in fresh water as well as in saline seawater?
As Archimedes discovered in his famous "Eureka!" moment, an object will float in water by displacing an amount of water with equal mass as the object. A ship floats because s displace a large amount of water, without submerging the decks. Any ocean ship will normally flat in freshwater; but because fresh water (having no salt) is less dense, the ship must displace a greater volume of water and will rest lower in the water line. Some river barges (such as on the Rhine) are so heavily laden, that they appear to be about to sink. But because rivers have no swell, it is perfectly safe. If such a barge were filled to the gunwales (i.e. filled right up) in a seawater-port such as Rotterdam, and then went into the fresh River Rhine, the barge would be in danger of sinking. (All vessels must have a Plimsoll line to show the permissible level to which a vessel may be safely laden).
Why is it that ship floats deeper in fresh water than in the sea water?
sea water is denser.
Why lines are important?
They indicate the density of the seawater, which determines how much lift-force the water can apply to the ship. So, basically, the lines show how much cargo a ship can hold in different water bodies.
Will a ship ride higher in inland freshwater lake or in the ocean?
Ocean. The ship will ride higher in salt water than fresh in water. There is a load line on the side of ships to tell you how deep you can load the ship. You can load the ship deeper if it is in fresh water because it will come up when it gets to the ocean.
What is an area where fresh water and salt water meet?
The area is in nautic terms called The brackwaters. its mostly at river mounds into the sea, where river water mixes with seawater. The word origins from the Frisian language. The mixed water itself is called brak water. I have been a seaman, and those expressions were normal use: Example: The ship now has reached the brackwaters of the Orinoco
