Question 1791Deck General70% to pass
A passenger vessel in river service which operates in fresh water at least 6 out of every 12 months since the last dry dock examination must be dry-docked at intervals not to exceed _______________.
AI Explanation
The correct answer is D) 60 months.
According to the regulations governing passenger vessels in river service that operate in fresh water at least 6 out of every 12 months since the last dry dock examination, they must be dry-docked at intervals not to exceed 60 months (5 years). This requirement is specified in the Code of Federal Regulations (CFR) Title 46, Section 176.600, which outlines the dry-docking and internal structural examination requirements for these types of passenger vessels.
The other options are incorrect because 12 months is too short, 24 months is too short, and 48 months, while longer than the other incorrect options, is still less than the 60-month requirement specified in the regulations.
