Example 1
You anchor in 15Ft of water (under your keel) at a time of day where the water is the highest
(High Water). Let’s say the High Water window shows 5Ft and the Low Water window shows
1Ft this means the water under your vessel over a 24 hour period of time could fall 4Ft (High
Water - Low Water). With your vessel in 15Ft of water and with a maximum water change
of 4Ftduring the day, the worst case situation there will be 11Ft of water under your vessel.
