🔍 Key Concepts

• 46 CFR Part 15 – Manning Requirements for towing vessels on coastwise voyages • Differences in able seaman (AB) requirements by tonnage (under/over 200 GRT) and voyage length (over/under 600 miles) • How to calculate percentage of ABs based on the total number of deck crew (excluding officers)

💭 Think About

• First, identify which specific 46 CFR 15 table or section applies to a 199 GT coastwise tug on a voyage over 600 miles • Think about whether longer voyages generally require a higher or lower proportion of ABs compared to short voyages • Ask yourself: if the regulation says “X out of Y deckhands must be ABs,” what percentage would that be?

✅ Before You Answer

• Verify you are using the section for towing vessels (tugs), not for cargo or passenger vessels • Confirm that the rule you’re reading applies to coastwise voyages over 600 miles for vessels over 100 but under 200 GRT • Once you find the required number of ABs, divide by the total deck crew (excluding officers) to confirm the correct percentage before choosing an answer
