Ruler and route planning

What you get

On board

• Measuring: distance and bearing per leg, plus the total distance. On the map a label with distance and bearing sits in the middle of each leg, which you can switch off with “Show labels”.
• Route from your boat as soon as you switch on “Dock to boat”:
  • The line runs from your boat to the next open waypoint and on to the destination.
  • Expected remaining time per leg and in total as well as expected arrival time.
  • How the app calculates: Remaining time is the distance along your route divided by your current speed over ground. The app smooths the speed so that short fluctuations do not make the time jump; the same current speed applies to all legs. The arrival time is the time now plus remaining time. If you are slower than 0.5 kn or your speed is older than 45 seconds, the app shows no time.
  • The app ticks off reached waypoints silently: when you come within 50 m or cross the line at right angles through the waypoint. If you skip a waypoint and are clearly sailing on a later leg, it ticks that one off too.
• Waypoint instruments in the Plotter, fed by the docked route:

• In the Plotter the ruler appears as its own page of the instrument bar, on the other maps in the sheet at the bottom edge.
• Point information: In view mode a tapped point shows the distance from the boat, coordinates and “True Bearing”.

Remotely

• On the map in the Dashboard and on the large sea map you measure distances and bearings in the same way. There are no remaining times remotely.

How it works

Measuring

1. On board open Menu › “Plotter”, remotely Menu › “Dashboard” or the large sea map, and tap the ruler symbol at the top right of the map. The map under “Monitor” has no ruler.
2. When first opened, the ruler is in edit mode and docks to your boat automatically if a position is available.
3. Tap the map: Each tap attaches a point to the end of the line.
4. You move points by grabbing and dragging them.
5. With “Done” you switch to view mode, with “Edit” back.

Docking the route to the boat

1. Switch on “Dock to boat”. The line now starts at your boat and moves along with it.
2. Waypoints you have already passed disappear immediately.
3. If you switch it off again, the line again consists of all set points.

Deleting points

• In edit mode tap a point and then the small × above it.
• Or tap the red × in front of a row in the list of legs. It deletes the end point of that leg.
• “Clear all” removes all points.

Closing the ruler

• Tap the ruler symbol again. Your points stay saved and appear again the next time you open it.

Requirements

• For measuring: only the map.
• For docking, remaining time and waypoint instruments: a live position, on board the app connected to the Hub.
• No internet, no account, no subscription needed.

Permissions and subscription

• Subscription: fully usable without a subscription; the Standard subscription adds nothing extra.
• Roles: The ruler works only on your device; everyone uses it the same way.

Notifications

None. The only notice is “Maximum of 50 points reached”.

Messages and special cases

Offline behaviour

• The ruler calculates entirely on your device, without internet.
• After an app restart your route is back, and a docked route continues with the next position.
• A Hub restart changes nothing about the route, only position and speed are briefly missing.
