What affects the level a cargo ship floats in water?
The design of the hull will determine what the displacement of water is. Also, the weight of the cargo in/on the ship.
What is the difference between a long ship and a knarr?
The knarr was a cargo ship, the hull was wider, deeper and shorter than a longship.The Knarr was a cargo ship, the longship was a battleship
Which of these hulls is a displacement hull?
a displacement hull is like a canoe's hull... it displaces water
How do you calculate ship lightweight?
simply, ship has three tonnage weights 1-Displacement :is the actual total weight 2-light weight :ship's hull, machinery and any fixed equipments. 3-dead weight : fuel,water ballast , fresh water , cargo,passenger and stores. then Displacement = Dead Wt + Light Wt displacement can be calculated from Block coefficients at certain drafts from ship hydrostatic curves eng.

Why does the ship float with so much steel and so many people in it?
It's a mathematical equation of buoyancy and mass displacement divided by actually weight.

What is a type of displacement hull?
A displacement hull is an efficient, non planing hull that moves through the water at 1.34 times the square root of the waterline length (LWL). This is not "directly" related to the designed displacement of the boat, that is, usually the weight of the boat, all additional gear, fuel, water, crew, cargo and everything else on board. Besides being efficient a displacement hull is usually more capable in rough weather and requires a relatively small inexpensive engine.
Does a PWC have a displacement hull or planing hull?
Planning hull
An observer noticed a large oil tanker parked at an oil terminal for 2 days. On the second day more of the hull of the ship was visible. Was the tanker picking up oil or delivering it?
A ship with a cargo rides lower in the water than when it has no cargo. As the cargo is unloaded, the ship rises in the water, revealing parts of the hull which had been below the water level. What the observer was looking at was a ship which was in the process of delivering its oil to the terminal.
Why do ships float on water but steel needles sink?
Buoyancy is based on average density, not the weight of the ship's hull. As it lowers into the water, the water displaced is lighter than the hull, but much heavier than the airinside the ship's hull. As long as the combined weight of the ship and its cargo is less than the water displaced by the hull, it will float. If, however, water fills the ship instead of air, the ship (as we all know) will sink.
Difference between displacement and planning hull?
A displacement hull always displaces an amount of water equal to the weight of the boat. A planing hull at a certain speed, will begin PLANING and rise partly out of the water, forced up by its v shaped hull, and only be displacing an amount of water equal to partial weight of the boat. A large ship, a tugboat, a barge, or a sailboat are displacement hulls. A speedboat or a jetski are planing hulls.
Formula for deadweight ton?
The deadweight of the ship is the result from the total displacement when loaded up to the summer freeboard mark minus the lightship displacement. The lightship displacement is the weight of the ship without any cargo, fuel, passengers, stores, mail, water and ballast.
