What is the distinguishing feature of an oceangoing ship?

An oceangoing ship is characterized by its capability to engage in international voyages and receive certification for ocean services. This means that these vessels are built to withstand the conditions of the open sea, which often includes extreme weather, larger waves, and longer travel times compared to ships that remain closer to shore.

The design and equipment of an oceangoing ship are specifically intended for navigating maritime challenges, which highlights the importance of certification. It ensures that the ship meets international safety standards, is adequately equipped for long-distance travel, and possesses the necessary documentation to operate in foreign waters.

In contrast, vessels that are confined to local fishing activities, lack required documentation, or face restrictions on operating distances from land do not qualify as oceangoing ships. They do not engage in the same level of maritime regulation or have the same operational capabilities as those ships that operate beyond national jurisdictions.
