Tide Arrow

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum jeokeefe,

The feature which you have selected is no way associated with tide/current data stored on the Navionics chart card. Like the other Chart application Vectors (MENU->CHART APPLICATION->PRESENTATION->VECTORS), the Tide vector is calculated from sensor data, in this case latitude, longitude, COG, SOG, Speed Through Water, and Heading. As the tide vector, better termed leeway vector is the vector difference of the through water and over ground vector, accurate presentation of this vector is dependent upon the system having each of the above listed sensor inputs and that each be properly functioning and calibrated.

If seeking information concerning the direction of the direction and magnitude of the tidal at any time based upon tide and current data retrieved from a Navionics chart card, then simply position the cursor over the current station icon, hold your finger on the station icon or press OK to bring up the chart object menu and then select Animate from the displayed menu.
