🔍 Key Concepts

• 46 CFR navigation equipment requirements for inspected vessels over 1600 GRT • Differences between equipment required for oceans/coastwise routes vs Great Lakes only routes • Which items are universally required on most large vessels (e.g., magnetic compass) vs those tied to specific routes

💭 Think About

• Ask yourself: which of these items is required on almost every large inspected vessel, regardless of route? • Consider which pieces of equipment are more critical for ocean/deep‑sea navigation than for vessels restricted to the Great Lakes. • Think about whether the regulations make a distinction between gyro compasses and magnetic compasses, or treat them the same.

✅ Before You Answer

• Check in 46 CFR whether gyro compasses are required specifically for Great Lakes‑only service or mainly for oceans/coastwise service. • Verify if a magnetic compass is a baseline requirement on all large vessels, even when a gyro compass is fitted. • Confirm whether the requirement to carry a deep‑sea hand lead applies to Great Lakes‑only vessels over 1600 GRT, or only to vessels on certain routes.
