yc is an acronym that stands for “Yacht Carrier,” which refers to a type of non-self-propelled vehicle transport barge used for carrying heavy loads. Yacht carriers are commonly used in various offshore projects, such as lifting and sinking ships. The development of ships has been closely tied to the progress of humanity. Ships have played a significant role in both wartime and peacetime. Millions of fishermen around the world rely on fishing boats to catch fish. Naval battles and military supply at sea are also closely related to ships. In 2007, there were approximately 35,000 commercial ships with a total cargo capacity of about 7.4 million tons. By 2011, there were approximately 104,304 ships registered with the International Maritime Organization (IMO) and assigned an IMO number.
