Dispersion relation for deep-water gravity waves; shallow water shortens wavelength at fixed period.
Practical use cases
Wavelength from Wave Period: passage planning, crew briefings, instrument-to-chart unit checks, and verifying mental math when tired or in rough weather.
Tips for accuracy
- Match input units to your chart, GPS, or instrument before trusting the Wavelength from Wave Period.
- Cross-check important outputs with a second method or crew when visibility or motion is poor.
- Treat simplified models (waves, radar horizon, etc.) as estimates; real conditions vary.
Practical examples
- 8 s period → ~100 m wavelength (approx.)
