The article describes what a hold is, what is it for, what types of transport have a hold, and what is its role in the modern world.
Ancient times
The widespread development of all the continents of our planet began only in the 17th century, and before that, the habitat of people was limited only to the lands where they were born and lived all their lives. The reason for such restrictions were the seas, oceans and imperfect methods of navigation, or even their absence. If, for example, you can explore the far and wild lands of your mainland or island on foot and on horseback, then the water spaces have become an insurmountable obstacle for our ancestors.
But gradually everything changed, and people began to master navigation. However, for a long time, all sea voyages represented only swimming in the zone of visibility of the coast, because there was no navigation.
Over time, the first navigation methods and devices were created, and then the widespread development of water spaces and the discovery of new lands that were on other continents began. And practically no ship could do without a hold. So what is a hold, why is it needed, and on which vehicles (except ships) does it happen? This we will understand.
Definition
According to the encyclopedia, a hold is the internal space of a ship between the deck and the bottom or the second bottom. Simply put, this is a room that is needed for the maintenance of goods, various supplies or housing of sailors. So now we know what a hold is.
Initially, the design of the ships of the hold did not provide. These include dragrakars. They were easier to manufacture, and the entire cargo with people was located on the deck. But as the range of the sea voyage increased, there was a need for a large number of supplies or living quarters for sailors, since you cannot solve the problem of hunger with only fish caught during the voyage, and you can’t live on the upper deck in any weather. And over time, the hold became an integral part of almost any ship.
So we figured out what a hold is. However, in what form of transport is there still a hold, except for ships?
Aircraft
With the development of aircraft manufacturing and regular passenger flights, the need for cargo compartments gradually arose. The reason for this was the constant modernization of aircraft, increased carrying capacity and the popularity of flights among people who wanted to take their personal luggage with them on the road. So the hold of an air vessel serves as a compartment designed for various cargoes, both in passenger and cargo or military aircraft.
