🔍 Key Concepts

• 46 CFR requirements for towing vessels over 12 meters operating on navigable waters of the U.S. • Minimum navigation safety equipment: what is explicitly required versus what is optional or recommended. • Difference between traditional navigation tools (charts, lights, radios) and electronic aids like GPS.

💭 Think About

• Look at which items are specifically named in federal regulations as required equipment for towing vessels of this size and service. • Ask yourself: which of these four items could a vessel reasonably navigate without, if it had to, while still complying with the law? • Consider which items support basic safety and communication, versus which items are more about convenience or enhanced navigation accuracy.

✅ Before You Answer

• Verify in 46 CFR Subchapter M (or applicable towing vessel equipment sections) which navigation safety items are explicitly listed. • Confirm that charts or maps of the area, a searchlight, and VHF-FM radio(s) all have clear regulatory bases for certain vessels and routes. • Check whether a GPS receiver is specifically mandated by regulation for towing vessels over 12 meters on inland/navigable waters, or if it is an electronic aid that is recommended but not strictly required.
