9.6 Navigation options The chart application provides features to help navigate to a chosen location. The navigation options are found in the Navigate menu: Menu > Navigate. • Goto Cursor — Will set the cursor position as the active destination. • Goto Waypoint — Provides options to navigate to a waypoint stored on the system • Follow Route — Provides options to navigate to a route stored on the system • Create Track — Will initiate a track on screen to plot your course as you progress. • Build Route — Provides options to build a route. Refer to the Using waypoints, routes and tracks section for further details. 9.7 Measuring distances and bearings You can use the databar and context menu information you can use the measure function to measure distances in the chart application. You can determine the distance and bearing: • from your vessel to the position of the cursor; • between two points on the chart. Measuring from vessel position to cursor From the chart application: 1. Select the location on screen that you want to measure the distance or bearing from your vessel. The chart context menu will be displayed. 2. Select Measure. The following will happen: • The measure menu will be displayed. • A line will be drawn from the cursor position to the center of the screen. • The cursor location will be moved at the center of the screen. • The bearing and distance will be displayed next to the new cursor location. 3. From the measure menu select Measure From so that Ship is selected. The ruler line is re-drawn from the cursor position to your vessel. 4. You can now adjust the ruler position by moving the cursor to the desired location. 5. If you want the ruler displayed after you have closed the measure menu, select Display Ruler so that On is highlighted. Selecting display ruler will switch the ruler On and Off. 6. If you want to adjust the range of the chart application whilst in the measurement menu select Adjust Range and use the Range Control to zoom in or out. Measuring from point to point From the chart application: 1. Select the location on screen that you want to measure the distance or bearing from your vessel. The chart context menu will be displayed. 2. Select Measure. The following will happen: • The measure menu will be displayed. • A line will be drawn from the cursor position to the center of the screen. • The cursor location will be moved at the center of the screen. • The bearing and distance will be displayed next to the new cursor location. 3. Select Measure From so that Cursor is selected. Selecting measure from will switch between Ship and Cursor. 4. You can now adjust the end point by moving the cursor to the desired location. 5. You can also Swap Direction of the ruler so that the bearing becomes the bearing from end point to start point. 6. If you want the ruler displayed after you have closed the measure menu, select Display Ruler so that On is highlighted. Selecting display ruler will switch the ruler On and Off. 7. If you want to adjust the range of the chart application whilst in the measurement menu select Adjust Range and use the Range Control to zoom in or out. 102 e7 / e7D / e95 / e97 / e125 / e127 / c95 / c97 / c125 / c127
9.8 Chart vectors Chart vectors display indicators for heading, COG, wind direction and tide direction. A range of vector graphics can be displayed in the chart application when in 2D chart view. The following vectors can be independently enabled or disabled: 6. Select a time setting or select Infinite. 7. Select Vector Width. A list of widths is displayed. 8. Select either Thin, Normal or Wide. 3 4 1 2 Item Descriptions 1 Wind arrow — wind direction is displayed as a yellow line with solid arrow heads pointing towards your vessel, indicating the wind direction. The width of the arrow indicates the wind strength. D11746-2 2 Tide arrow — tide is displayed as a blue line with solid arrow head pointing away from your vessel, in the direction of the tidal set. The width of the arrow indicates the tide strength. 3 COG (Course Over Ground) vector — a green line indicates the vessel’s actual course. A double arrow head is used if the vector length is set to a value other than infinite. 4 HDG (heading) vector — a red line shows the vessel’s heading. An arrow head is used if the vector length is set to a value other than infinite. Note: If Speed Over Ground (SOG) or heading data is not available, vectors cannot be displayed. Vector length The length of the HDG and COG vector lines is determined by the distance your vessel will travel in the time you specify at your current speed. Enabling and disabling chart vectors In 2D chart view: 1. Select Menu. 2. Select Presentation. 3. Select Layers. 4. Select Vectors. 5. Select the relevant menu item to switch Heading Vector, COG Vector, Tide Arrow, or Wind Arrow On or Off as appropriate.

head is used if the vector length is set<br />
to a value other than infinite.<br />
Note: If Speed Over Ground (SOG) or heading data is not<br />
available, vectors cannot be displayed.<br />
