Refer to the image above. The time (1) displayed corresponds to the location of the cross-
hair cursor (3) in the Tide Graph (2). Moving the ShuttlePoint knob to the left or right changes
the time, moving the ShuttlePoint knob up or down selects the Tide height and draught
(draft) on the Tide Graph.
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 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.
