Question 351General Subjects - 1st Asst/Chief

The correct answer is B) 20%. Vessels enrolled in the Continuous Machinery Survey program are required to have approximately 20% of their machinery surveyed each year throughout the Special Survey cycle, which typically lasts 5 years. This ensures that all machinery is inspected over the course of the full Special Survey period, providing a comprehensive assessment of the vessel's machinery condition. The other options are incorrect because 10% would be insufficient, 25% would be too high for an annual survey, and 50% would be unrealistic to achieve each year.
