Understanding Tides and Datums: LAT, HAT, Mean Sea Level, MHWS, MLWS, MHWN, MLWN

In this video, we take a deep dive into the key tidal datums used in navigation and hydrography. Starting with Lowest Astronomical Tide (LAT), we then explore: Highest Astronomical Tide (HAT) Mean High Water Springs (MHWS) Mean Low Water Springs (MLWS) Mean High Water Neaps (MHWN) Mean Low Water Neaps (MLWN) Mean Sea Level (MSL) You’ll learn: ✅ What each datum means and how it’s determined ✅ Why these reference levels are essential for safe navigation ✅ How they are used in nautical charts and tidal predictions If you found this video helpful, don’t forget to Like 👍, Share 📤, and Subscribe 🔔 for more maritime education content! #Tides #Navigation #MaritimeTraining #NauticalCharts #LAT #HAT #MeanSeaLevel #MarineNavigation #NauticalChart #UnderKeelClearance #Seamanship #MarineTutorial #ENC #TideAndDraft #maritime #seafarer #seaman #bsmt #maritimestudents #nauticalacademy
