To turn On	Tap the My Location tab while the chart is showing.
To turn Off	Drag the chart.

Display of your current location requires a GPS chip found in all iOS devices that have the ability to connect to a cellular network, or an iOS-compatible external GPS receiver.

The ETA shows the time in the current time zone even if the destination is in another time zone. The background color of the Estimated Time of Arrival changes according to the sun's position to warn you if you will be arriving after the sun sets at your destination.

Daytime:     3:41 PM  ETA

Twilight:     7:19 PM  ETA

Dark:     9:56 PM  ETA

When the Location Accuracy text turns red with a yellow background, this indicates that the GPS satellite signals are not being received properly. Therefore your position may be off. Poor reception may also cause high errors in speed and course measurements.

The GPS-measured course accuracy gets better at higher speeds. When nearly stopped, the course direction is undefined.

 056 ±37°  HDG 

When the Heading Accuracy text is red or the heading seems incorrect, recalibrate the internal compass to improve the heading accuracy. Imagine arrows sticking out of all 4 sides and the front and back of your device. Rotate the device in several different ways so that each of the 6 arrows will at some time be aimed at every area on an imaginary sphere surrounding you. If this does not improve the accuracy, then move farther away from all electrical devices or metal, and repeat. The actual heading error will be greater than the displayed accuracy if near magnetic material such as steel, or your device is not aligned with the boat centerline.

In the Chart Area

The direction of the Course Indicator shows Course Over Ground (COG). The length of the Course Indicator is proportional to the square root of Speed Over Ground (SOG).

At very slow speeds, a gray Compass Heading Indicator is shown instead of the blue Course Indicator, because GPS Course measurements are not accurate at very slow speeds.

If the Compass Heading Indicator turns red or seems to be pointing in the wrong direction, recalibrate the internal compass to improve the heading accuracy. Go through the normal compass calibration movements even if you don’t see the prompt to do so. Imagine arrows sticking out of all 4 sides and the front and back of your device. Rotate the device in several different ways so that each of the 6 arrows will at some time be aimed at every area on an imaginary sphere surrounding you. If this does not change the Compass Heading Indicator to gray, then move farther away from all other electrical devices and metal, and repeat. The displayed Heading Indicator will only be correct if the internal compass is calibrated and your iOS device is physically aligned with the boat and away from magnetic materials.

Chart Stitching

The option to stitch adjacent Mercator charts together is selected using the Settings App.
Chart stitching is OFF by default.

Stitch Charts OFF	Stitch Charts ON
Only one chart is shown.	Multiple charts are shown.
Chart margins are shown.	Chart margins are hidden.
Fastest chart display.	Slower when multiple charts are on screen. Zoom in to speed up.
Tab Bar Icon	Tab Bar Icon

When two adjacent charts partially overlap or you see  Selected chart (✓) is offscreen , to bring the back chart to the front, double-tap it to select it, or tap its name on the Chart List screen.

Only charts which use the same map projection will stitch together. Most NZ RNC Marine charts use the Mercator map projection. Any Mercator chart will stitch to any other Mercator chart that either touches it or overlaps it, as long as the scales of the two charts are not too different. NZ Mariner Transverse Mercator (TM) charts will not stitch.

iSailGPS NZ uses the characteristics of the selected main chart to pick a useful visible grouping. The chart you select is always on top and fully visible. iSailGPS NZ may add charts to and remove charts from the group as you pan around and zoom. If you pan too far away from the selected chart, the other charts will disappear from the screen. So select one of the visible charts by double-tapping it after you pan to a new location.

If you zoom out too far, the display update speed may get very slow. NZ RNC Marine charts are huge images (up to 71 megapixels, 34 x an HDTV picture). Displaying the zoomed-out image of many of these stitched together can take many seconds. We haven’t prevented you from doing this, as sometimes the zoomed-out display can be very useful. But most of the time, keep the zoom level such that you can read the water depth numbers on the charts for quick interactions. If you need more of an overview, select a chart with a larger scale. On older, slower, and smaller RAM memory devices, you may need to turn off Stitch Charts to avoid too-slow display updating and out-of-memory problems with very large charts.

While navigating to a Go To waypoint, the Waypoints tab looks like this

and the top bar of the My Location screen shows this navigation information at very slow speeds:

The Estimated Time of Arrival is recalculated every few seconds, based on the your travel history since the Go To waypoint was set, and assuming that the trip ahead is similar in speed and direction. The ETA will not appear until you have sailed for a couple of minutes with track recording turned on, so your speed can be more accurately determined.

At faster speeds the Course Over Ground (the direction you are moving relative to ground-based locations) will be shown in black text instead of the compass reading in gray text.

HOW TO	DO THIS

Cancel	Keep the route as it was with no changes.
Done	Save changes to the route.

Route waypoint names are shown in Italics  to distinguish them from regular waypoints.

Each waypoint entry in the table shows the great circle distance and bearing from the previous waypoint and the total distance along the route. When the distance is long enough that the bearing changes along the path, the “at” bearing is the bearing leaving the previous waypoint, and the “to” bearing is the bearing arriving at the new waypoint.

The route screen shows newly added or edited waypoints in red.

If a route waypoint is identical to a regular waypoint, then they are linked so that only one of them shows on the chart. To break the link:

• Edit the route waypoint      or
  
• Edit the regular waypoint when the route containing the route waypoint IS NOT selected on the Routes screen.

To edit a waypoint without breaking the link:

• Edit the regular waypoint when the route containing the route waypoint IS selected on the Routes screen.

Deleting one of the linked waypoints will not delete the other.

Some paper charts have insets, such as closeups of harbors, in addition to the main chart. These insets are provided as separate digital charts. To download all available sections of one chart, select the chart, then tap  Add Selected Chart and All Its Insets  .
(Not available on devices with a 3.5" screen.)

The Chart List screen shows newly added charts in RED.

You can store a few charts or charts for the entire country on your iOS device. They are sorted, first by center latitude and then by center longitude, so charts for adjacent areas tend to be close together in the list.

The names of charts that are currently being shown on the My Location page are shown in BOLD text on the Chart List page.

* The Satellite Map Locator also shows the border lines of your already-downloaded charts:

HOW TO	DO THIS
Open a chart for a point on the Satellite Map Locator screen	Pan the locator map to center the point at the crosshairs intersection. Tap  View On A Chart  . If no chart for that point has yet been downloaded, the chart download screen will appear, allowing you to download one.

Note the Chart Name near the top of the screen. Tap  Cancel . Tap  Cancel . The chart list will scroll so the desired chart is visible near the center of the screen.

To Download Charts with Multiple Sections

* Each paper chart has a number, such as nz5124, assigned by LINZ to the chart.

Many paper charts have multiple charts printed on one piece of paper. For example there may be one chart section showing an entire bay, and a second chart section showing a close-up of a harbor.

For digital charts, these individual chart sections are indicated by a two digit section number added to the end of the chart number. The main chart section is indicated by 01 at the end, for example nz512401. The close-up sections are indicated by 02, 03, etc.

On paper, the close-up chart sections are often shown as insets. In iSailGPS NZ, each chart section is shown individually so that each can have its location properly georeferenced.

To manually download separately each individual section of a multi-section chart:

1. Tap the Chart List tab.
2. Tap  +  .
3. Tap  Place Name or Chart Name .
4. Enter only the main paper chart number under  Search for the Coordinates of .
   For example enter nz5124, not nz512401.
5. Tap  Search  on the keyboard.
6. In addition to returning location coordinates, under  Search for the Coordinates of  iSailGPS NZ will return the full chart number for the last available chart section. For example enter nz5124, tap  Search , and you will see nz512403. The 03 on the end means that chart nz5124 has three chart sections.
7. To download all three sections individually, download charts nz512403, nz512402 and nz512401.

   Enter the full chart number under  Search for the Coordinates of .

   Tap  Search  on the keyboard.

Always carry a compass and paper charts as a backup. The marine charts used in this app were last verified by LINZ on 7 December 2023. If your use requires that the information on the chart be more recent than 7/12/23, then don’t use iSailGPS NZ. Don’t run your battery down so far that you can’t make an emergency call if needed. James Associates Inc. accepts no liability, including incidental or consequential damages, for any injury or damages that may occur from the use of iSailGPS NZ.

For compliance with Maritime New Zealand requirements refer to Maritime Rules Part 25. The use of iSailGPS NZ does not relieve the user of their obligations under New Zealand law and international convention.
