Each vessel shall be dry-docked or hauled out at intervals not to exceed 2 years if operated in salt water for a total of more than __________. (small passenger vessel regulations)

Correct Answer: Option A — 3 months in any 12 month period since it was last hauled out

Per 46 CFR 176.600, vessels operating in salt water for more than three months in any 12-month period must be dry-docked or hauled out at intervals not exceeding two years. This requirement ensures the hull and underwater appendages are inspected for corrosion, fouling, and structural integrity.
