Installing Orca in your boat

Getting started with Orca


Tools and functionality



Orca runs on our tailor-made Orca Charts – the next-generation charts that are crisp and easy-to-read with instant response. The charts are built on top of data from Official Hydrographic Offices and augmented with in-house data for improved accuracy and coverage.

Orca Charts in brief

  • Navigate with confidence on charts built from official hydrographic data.

  • Carefully designed for legibility, clutter-free at any zoom level, even in complex areas

  • Easy on the eyes – with symbology and iconography that closely resemble traditional paper chart design

  • Runs on a blazingly fast chart rendering engine. Zoom and pan with instant response

  • Contains thousands of anchorages, marinas, and fuel stations – with hundreds of thousands of ratings and reviews by fellow boaters

  • Automatically updates whenever new chart updates are available

Explore the charts

Orca charts behave just like other maps you are used to on your phone and tablet. Pan, zoom in and out, and rotate the map freely with the gestures you already know:

  • Drag to pan the chart

  • Pinch in and pinch out to zoom in and out

  • Rotate with two fingers to rotate the chart

As you zoom in, the details shown in the map increase gradually.

Where other chart providers offer large stepwise increases in detail as you zoom into the chart, Orca Charts provide a carefully designed and gradual increase of details as you zoom in.

This careful balance means that you are able to view navigation-critical information, such as shallow rocks or soundings more easily without having to zoom far into the charts.

You can notice this effect in the video below – Orca Charts have no abrupt change in detail level as you zoom in, and critical information such as navigation marks and rocks stay visible and legible at all times.

Finding your location

The Follow Me button moves the chart to your current location.

On large screens, such as on tablets, the button is placed along the right side together with a pair of zoom buttons. On smaller screens, the Follow Me button is positioned in the bottom right corner.

The Follow Me button can be tapped multiple times with different results:

  • First tap – The charts center on your location and orientates itself course-up

  • Second tap – The chart centers on your location and orientates north-up

After pressing the button, the map camera will follow you so you are always at the center of the screen.

If you interact with the chart, such as panning or zooming, the chart will stop following your location. To make the chart follow your location again, tap the Follow Me button again.

If you rotate the map, sometimes you may want to return the chart rotation to North. To do so press the Compass button on the top right side of the screen.

The video below shows how the Follow Me and Compass buttons work.

Pin a location

Long press in the map at a location to take action or get information about that specific location.

A menu will appear at the bottom of the screen with the following information:

  • The coordinates of the location

  • The distance and bearing from your current position

There are several actions you can take in that menu

  • Press Save to save the location as a Spot

  • Press Weather to see the marine weather forecast for that location

  • Press Measure to enter the measure distance mode, more on that below

  • Press Navigate to enter routing mode and calculate a route to that location

  • Press Info to view detailed information about the mark or area nearby the pin. This option is only visible when you press at or near a mark or area with special navigation information.

Measure distance

The distance tool lets you calculate the distance and course between two points.

To measure distance, pin a location by long-pressing in the chart. Press Measure and a ruler will appear between your current location and the pinned location.

The ruler will show the distance and the course between the points.

To adjust the ruler, hold and drag the endpoints to move them around.

Chart settings

Orca Charts can be adjusted to behave the way you want them to do – from visual representation to how they behave when you move around in the charts.

To edit your chart settings, go open the Main Menu > Settings > Chart.
