Question 1 of 31048

🔍 Key Concepts

• 46 CFR requirements for drydock examinations and internal structural examinations for cargo vessels • Difference in inspection intervals for vessels operating exclusively on the Great Lakes vs those operating on oceans or coastwise routes • How a vessel’s service route over the certificate period (Great Lakes + transatlantic) affects which interval applies

💭 Think About

• Ask yourself: Does this vessel count as an ocean-going vessel, a Great Lakes-only vessel, or a combination for inspection purposes? • Think about the typical inspection cycle length (in years) and how many times a vessel must drydock within that cycle for its route type. • Consider whether a vessel that regularly makes transatlantic voyages is allowed the same long interval as a vessel that never leaves the Great Lakes.

✅ Before You Answer

• Verify in 46 CFR the drydock interval table for cargo vessels (freight vessels) by route: ocean, coastwise, Great Lakes, or rivers. • Check whether a vessel that operates even part of the time on oceans/transatlantic service must meet the stricter (shorter) interval rather than the more lenient Great Lakes-only interval. • Confirm the maximum months allowed between drydockings for a single-hull cargo vessel in ocean or ocean/Great Lakes service, then match that number to the closest choice.
