The Tide tab contains twosub tabs: Tide and Current.Tide Sub TabThe Tide sub tab contains a graphical chart that shows Tide Station informationin a 24-hour span starting at midnight. You can choose from different dates andmore than 3,000 Tide Stations around the U.S.A. coastline, Alaska, Hawaii,western Canada, and several of the Caribbean islands. The top of the Tide sub tabshows the Tide Station and the date. The bottom of the Tide sub tab shows thedistance and bearing from your location.The bottom of the Tide chart shows a 24-hour block of local time for yourlocation. Daylight (yellow bar) and nighttime (blue bar) at the Tide Station areshown across the time scale, with the time progressing from left to right (sunriseand sunset information might not be available for some Tide Stations). The solid,light vertical lines are in 4-hour increments, and the light, dotted vertical lines arein 1-hour increments. A solid, vertical line (with the local time at the top) indicatesthe tide height corresponding to the time shown in the local time box.NghtLow tde curveEvent tmesMn. levelMax. levelLocal tmeDayHgh tdecurve Tme bar Current tdeheght barCurrenttdeheghtThe Tide curve is shown as a shaded area, where higher tides are taller (blue) andlower tides are shorter (red). The solid, horizontal line indicates the tide height.The figure to the left of the line shows the present tide level. The Mean LowerLow Water (MLLW) appears as a solid, horizontal line near the bottom of the chart(this line appears only if the tide height range is zero or below). The numbers onthe top and bottom of the left side indicate the maximum and minimum levels. Thefour data fields below the chart indicate event times and levels at which the tidechanges, starting in the upper-left field, going downward, then to the upper-right,and down again. When comparing with other tide tables, verify that the depth unitsare the same for both sources. The bottom of the chart shows the amount of time(in hours and minutes) until the next low tide and high tide.
