🔍 Key Concepts

• 46 CFR Subchapter T requirements for navigation equipment on small passenger vessels • Differences between ocean/coastwise, lakes, bays and sounds, and river routes • Why a magnetic compass is safety‑critical in certain operating areas

💭 Think About

• In which service is a loss of electronic navigation (GPS, plotter, etc.) most risky for finding safe water and landfall? • Which route type is most exposed to open sea conditions, poor visibility, and being far from familiar landmarks? • Which services operate close enough to shore or within well-marked, confined waterways that they might rely more on visual ranges and fixed aids to navigation?

✅ Before You Answer

• Verify which route(s) 46 CFR Subchapter T explicitly mentions when requiring a compass as part of the navigation equipment • Check whether the rule distinguishes between ocean/coastwise vs. lakes, bays and sounds vs. rivers • Confirm that there is no blanket exemption saying no compass required for all T‑boats
