NOTE
The draught window shows the height of the tide water during a 24hr period of time. For example
if the ShuttlePoint knob is pressed up to move the cursor to the top of the Tide Graph this is the High
Water Level and if the cursor is moved to the bottom of the Tide Graph the draught will show the
Low Water Level.
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 4FT during the day, the worst case situation there will be 11FT of water under your
vessel.
