🔍 Key Concepts

• VHF Channel 13 is the "bridge-to-bridge" navigation safety channel in U.S. waters • Normal operating power vs. maximum available power on a VHF radio • Why lower power is preferred for ship-to-ship navigation safety communications in congested areas

💭 Think About

• Ask yourself: Is Channel 13 meant for long‑range calls or short‑range navigation safety between nearby vessels? • Think about which power level would help avoid interfering with many distant ships all at once. • Consider typical fixed‑mount VHF radios: what is their high‑power setting, and what is the reduced‑power setting usually used for close‑range work?

✅ Before You Answer

• Verify in the Navigation Rules and 47 CFR Part 80 (FCC maritime)** that Channel 13 is specifically a "bridge‑to‑bridge" channel used for navigation safety. • Check what power level is designated as normal operating power for Channel 13, and note that higher power may be allowed only in special circumstances. • Confirm which of the listed wattages matches the low‑power setting on most marine VHF sets used to limit range and reduce congestion.
