Raymarine a50 User Guide

Your current position  is represented by a boat  symbol. Your 
position is also displayed in the data bar under VES POS. 
A solid circle on the chart indicates that neither heading nor 
Course Over Ground (COG) data is available. 

If your position is outside the area of chart currently shown in the 
chart window, the vessel symbol will not be visible. You can tell the 
system to locate your vessel and centre the chart display about it. 

1.  Press the FIND softkey to switch between the SHIP and Cursor 

location.

To move around the chart and display the area required at an appro-
priate scale, use the track pad and range in/out buttons.
Note: Remember that the cartographic detail available on the chart 

will vary according to the chart and chart scale. Some charts 
provide details at smaller scales than others.

            

A feature of the chart application is ‘autoscale’. If you select a chart 
scale that does not have cartographic detail in some areas, the 
chart will automatically use the most detailed level available for the 
surrounding area and stretch it to fit the selected scale. This means 
that you will never have blank or hatched areas on the screen. How-
ever, there may be some misalignment of objects which cross the 
chart boundary in this area.
