What is responsible for keeping a sharp watch to avoid collision between two boats?

The responsibility for keeping a sharp watch to avoid collisions between two boats typically falls on the crew members, particularly the officer on watch. They must remain vigilant, monitor navigation instruments, and maintain visual observation of surrounding vessels. Additionally, the use of radar and communication with other boats can enhance situational awareness and help prevent accidents. Adhering to maritime navigation rules and protocols is also crucial in ensuring safe passage.
