Ham Radio for Sailing and Boating: Stay Connected at Sea

Your Backup When Marine VHF is Not Enough

Marine VHF is mandatory on boats — but its range is limited to line-of-sight, typically 5-15 miles. When you are offshore or in an emergency, ham radio provides options that marine VHF cannot. Here is how to add ham radio to your sailing kit.

Why Ham Radio Complements Marine VHF

Marine VHF Ham Radio
Range 5-15 miles (line of sight) 50+ miles via repeaters, worldwide via HF
License Station license only Individual license required
Emergency Channel 16 — coast guard Multiple options: repeaters, HF, Winlink email
Weather WX channels NOAA + ham weather nets

What to Pack on Your Boat

  • Waterproof handheld: UV-K1 or K5 with a dry bag
  • External antenna: Mount on the mast or rail — dramatically better than handheld antenna below deck
  • USB-C power bank: Solar-chargeable for offshore independence
  • Float strap: Because radios sink fast

Maritime Ham Frequencies

  • 146.520 MHz — 2m National Calling
  • Maritime Mobile Net — 14.300 MHz (HF, SSB)
  • Local repeaters near coastal areas
