The phrase describes a method for individuals to evaluate their comprehension of navigation regulations governing vessel operation. These assessments often simulate examination conditions, presenting questions based on the content of the official navigational rules. The aim is to enhance understanding and retention of crucial maritime knowledge. An example involves a series of multiple-choice questions covering topics such as right-of-way determination, sound signals, and navigational lighting.
Proficiency in the established guidelines is paramount for safe navigation and the prevention of collisions at sea. Using self-assessment tools can significantly improve an individual’s preparedness, building confidence in their ability to apply theoretical knowledge in real-world scenarios. Historically, mariners relied solely on textbook study and practical experience; modern tools offer a supplementary, structured approach to verifying one’s understanding and identifying areas needing further study.
