James Cook was an intelligent and skilful navigator, and his maps and charts were so well prepared and exemplary that some of them were used even after his death. His wise and amiable character endeared him to everyone, including his crew members, and the natives of the lands he visited.
He was the first captain to know his position on the surface of the globe within a few nautical miles. He was an excellent disciplinarian, and always commanded respect from his men.
He always had a great appetite for knowledge. He was much more scientific than many explorers of his time. He was the first sailor to use a nautical almanac and chronometer during an expedition. He even took a professional astronomer to enable him to calculate his longitude from the observations of the Moon. Cook is also remembered for navigating by latitude and longitude.
Cook was the first sailor to find an apt remedy for scurvy. He knew that shortage of vitamin-rich food was the main reason behind scurvy. He stocked up fresh fruits and vegetables in his ship, and collected more from the islands he visited on the way.
