Safety Alerts

The Safety Alerts feature included with Zeus S can constantly monitor your course for dangerous chart objects no matter what your speed, zoom level, or view. Whether it’s a buoy, shallow water, rocks, or land Zeus S can warn you in advance.

  • CMAP® Discover  X and Reveal  X charts provide detailed chart data available at all times to Safety Alert
  • Alerts provide the sailor with awareness of potentially dangerous charted objects above and below the waterline
  • Automatically identify charted objects which are of concern, warning, or critical based on their relative time and distance
  • ‘Harbor’ and ‘Offshore’ modes allow Zeus S to automatically change the time and range sensitivity based on the use 
  • Ideal for use in unfamiliar waters or at night when visibility is reduced to identify dangerous objects.

Quick Race Entry

  • Quickly create a race route from the sorted list of waypoints
  • Easily add port and starboard rounding indicators
  • Intuitively add, remove or reorder a race route
  • Use the Race overview tool to brief your race crew with expected wind angles and estimated sailing time for each race leg to aid decision-making and sail selection

Start line

  • The powerful Zeus Start Line tool is now chart based to allow navigational awareness during the start procedure
  • Start line view, including laylines, favored end, tide set & rate, and True Wind Direction
  • The chart dynamically orientates and zooms to ensure the boat and start line are in view
  • Calculations are based on the yacht’s Bow Position via an offset distance for the GPS
  • Zeus S Internal GPS (or optional external options) provides precise position 10 times per second
  • Simple setup - set the port and starboard start line end positions via a button press (“ping”), waypoint, or cursor
  • Easily return to view the start line on the chart via an edge marker
  • Zeus S automatically captures your distance to the line when the race timer reaches zero

B & G pioneered laylines in chart plotters with the original Zeus®. Zeus S laylines provide a powerful decision-aiding tool.

  • Overlay your target sailing angles, upwind or downwind, to your destination on the chart
  • Enable wind history to show a wind shift heat map, which intensifies the colors over time to show the history of true wind direction
  • Mini Inspect (short press) a layline to gain detailed target sailing angles, speed, SailingTime, and distances
  • Full Inspect provides detailed sailing information on current and opposite tacks
  • Apply tidal correction to layline calculations
  • Display laylines using actual data or input targets.

Time to Cursor

Have you ever wanted to know how long it will take to sail to a location on the chart or do you need to tell your race crew how long to go?

Simply place the cursor anywhere on the chart to show an estimated sailing time and distance information to the cursor position.

Ideal, when you’re navigating to a waypoint and you need to know the sailing time to a secondary position.

Tide Gauge

Need to know the state of the tide quickly? Zeus S provides at a glance tidal data

  • Graphically see a tidal histogram including current time indication in the instrument data bar
  • Choose between the automatic selection of the closest tidal station, or selecting a specific station
