Navigating to a Point on the Chart
CAUTION
The Auto Guidance feature is based on electronic chart

clearance. Carefully compare the course to all visual sightings,
and avoid any land, shallow water, or other obstacles that may
be in your path.
When using Go To, a direct course and a corrected course may
pass over land or shallow water. Use visual sightings, and steer
to avoid land, shallow water, and other dangerous objects.

indicates a falling tide, and a blue arrow pointing upward
indicates a rising tide. When you move the cursor over the tide
station indicator, the height of the tide at the station appears
above the station indicator.
Current direction indicators appear as arrows on the chart. The
direction of each arrow indicates the direction of the current at a
specific location on the chart. The color of the current arrow
indicates the range of speed for the current at that location.
When you move the cursor over the current direction indicator,
the specific current speed at the location appears above the
direction indicator.
