🔍 Key Concepts

• Official Logbook requirements in 46 CFR (look at thresholds for tonnage and voyage type) • Difference between coastwise and foreign/ intercoastal voyages • How gross tonnage (G.T.) and voyage length/route affect logbook requirements

💭 Think About

• First, separate the choices into coastwise trips versus long intercoastal/near-foreign style trips across U.S. coasts. • Compare the gross tonnage of each tug to the minimum tonnage that triggers the Official Logbook requirement. • Ask yourself which factor is decisive: is it distance, route type, or tonnage — and which combination actually appears in the CFR wording?

✅ Before You Answer

• Verify in 46 CFR which vessels are required to carry an Official Logbook by tonnage and voyage. • Check carefully whether U.S. intercoastal voyages between Atlantic and Pacific coasts are treated more like foreign voyages for logbook purposes. • Confirm that a purely coastwise voyage of limited distance, even on a larger tug, may not meet the same requirement as a longer intercoastal/‘foreign‑type’ voyage.
