Raymarine LIGHTHOUSE 3, Advanced Operation Instructions

Page: 185 / 450

Note:
You should not steer your vessel so that its heading points exactly along the layline. Instead try
to align your Course Over Ground (COG) with the visual laylines, as well as using the information
displayed on the Sailing page in the
Dashboard app to help you steer to your optimum wind angle.
Your vessel should then travel along the layline, under the effects of tide and leeway.
Sailing data page
Sailing data and dials are available for display alongside laylines to help indicate which direction to
turn in order to maximise your VMG to windward.
Sailing dials can be displayed in the Dashboard app by selecting the Sailing default data page. For
more information on customizing the Sailing data page, refer to Chapter 13 Dashboard app
