These image pairs (labeled 1 & 2) are from a B&G Zeus 3 MFD with input from the Furuno SCX20 compass. Each pair represents nearly the same moment in a race in different views.

1. The Sailsteer view (left) shows Strider heading 283M degrees on port tack, a .69-knot current (blue arrow), and the need to tack in less than 3 minutes (red box upper right). The chart view (right, enlarged for detail) shows the race mark flag and the boat perpendicular to the next layline (green line).

2. This pair of images, recorded after tacking over to port tack (202 degrees), shows the full chart view, along with the adjacent databoxes.

3. This page view, with boat heading 208 degrees (red box), shows several functions illustrated in the pairs above, but strictly in numerical format.
