Over the past century, ship technology has evolved dramatically. Modern vessels are faster, safer, larger, more efficient, and far more technologically advanced than ships from the early 20th century. Understanding these changes reveals <strong>how engineering, automation, and globalization transformed maritime transportation<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator
