Chart Window and Chart Settings Window

In this window, the vessel is being navigated to the popular San Francisco waypoint BLKALL (Blackaller). The blue line shows the course to the active waypoint and the trailing dashed line shows the track history. At the side of the chart, the distance and bearing to the active waypoint are shown.

The following window shows a similar example using a PhotoNavigator aerial view chart.

Overview Window

Shows the entire chart allowing any portion to be selected and shown in the Chart Window.

Waypoints Window

Double clicking on the chart creates a new waypoint. Waypoints can be edited in place and saved and deleted and made active.

Routes Window

Routes can be created using waypoints. The selected route is plotted on the chart.

Track Window

The historical position is stored. Selecting any row plots the past position on the chart including bearing and speed. In this example the Route from SAPRCH to GGBRG is shown with the actual sailed track.

AIS & Radar

Connect a readily available AIS (Automatic Identification Receiver) or Radar to your Mac and "see" local vessel traffic.

Tides & Currents

Click anywhere on the chart to get a tide or current graph via Mr. Tides.


Using readily available and free GRIB weather forecast files, wind speed, wind direction, pressure, air and sea temperature are plotted on the chart. Both traditional vectors with barbs or Beaufort scale filled vectors are available. Selecting the forecast is as easy as picking the date/time from the list.
