Ships determine water depth using a device called a sonar, which emits sound waves that travel to the seabed and back. By measuring the time it takes for the sound waves to return, the system calculates the depth based on the speed of sound in water. Additionally, navigational charts and GPS data can provide information about known depths in specific areas. Together, these methods ensure safe navigation and help avoid underwater hazards.
This is deep water so ships can sail through. Becouse ships need deep water to sail through places
They need to be built in areas with water deep enough for them. Most ships sit fairly deep in the water even when empty and the coast offers that for them.

Rusting is the result of oxidation of iron (steel). Theer's more dissolved oxygen in shallow water than there is in deep water.
One reason is the size of the ships, the water is not deep enough.
