Marine vessels are watercraft designed for navigation on oceans, seas, and other bodies of water. They come in various types, including cargo ships, fishing boats, and yachts, each serving specific purposes. These vessels can be powered by engines or sails and vary in size from small boats to large ships. Marine vessels play a crucial role in global trade and transportation. They are used to move goods, people, and resources across vast distances. Additionally, they contribute to recreational activities and research, helping scientists study marine ecosystems and the effects of climate change on our oceans.
