Race Start Page - Raymarine LIGHTHOUSE 4 Operation Instructions Manual

22.6 Race start page

The race start data page is available when the MFD has been configured to
use the Sailing boating activity during the initial MFD start up wizard. The
race start page includes data relevant to race sailing and includes a graphical
sailing dial.
The apparent wind dial is the default dial displayed on the race start page.
When the [Sail performance] setting has been configured dynamic wind angle
targets will be displayed. The sail performance setting can be configured from
the [Boat details] menu: [Homescreen > Boat details > Sail performance].
If the [Sail performance] setting has not been configured then close hauled
angle indicators are displayed instead of wind angle targets.
The race start page can be used in combination with the Laylines feature
and race start line feature available in the chart app to optimize your sailing
performance. For details about the layline features refer to:
• p.220 — Laylines
• 15.5 Race Start Line (SmartStart) and Race Timer
