Tides & Currents Tide or current data is overlayed onto the electronic chart display in MaxSea with one button-click. The display icons on the chart indicate direction and strength of current(orientation and size of arrow), or state tide(height of yellow column, direction of chevron). Tide displays are updated continuously. You may view the tide/current data for any time in the past or future. MaxSea also makes it easy to advance time and watch how  tide and current data progress. These display icons give you the information you need as you are planning or navigating. Double-clicking on any tide or current icon gives you a complete graph for that station.
