Which of the following is NOT an advantage of using ECDIS?

Choosing increased paperwork as the answer indicates an understanding that it is contrary to the benefits offered by ECDIS (Electronic Chart Display and Information System). ECDIS is primarily designed to streamline navigation processes, thereby reducing the administrative burden on navigators and minimizing paperwork.

The advantages of ECDIS include enhanced command and control, which refers to the system's ability to provide real-time situational awareness through integrated navigation data. Improved safety is another key benefit, as ECDIS enhances decision-making with accurate data, reducing the likelihood of navigational errors and accidents. Furthermore, ECDIS can potentially reduce manning requirements since it automates many tasks traditionally performed by crew members, allowing for more efficient use of personnel on board.

Thus, the identification of increased paperwork signifies an understanding that ECDIS aims to alleviate rather than contribute to administrative tasks, aligning with its design and purpose in modern maritime navigation.
