Example 1
You anchor in 15Feet 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 5Feet and the Low Water
window shows 1Feet this means the water under your vessel over a 24 hour period of time
could fall 4Feet (High Water - Low Water). With your vessel in 15Feet of water and with a
maximum water change of 4Feet during the day, the worst case situation there will be
11Feet of water under your vessel.
