Plotter and instruments
The Plotter is your main screen on board: a map and an instrument bar that you fill yourself. 33 instruments are available, from speed and course through wind, depth and air pressure to waypoint and performance values. If your engine sends data into the NMEA 2000 network, engine instruments such as RPM, oil pressure, temperatures, alternator, fuel consumption and gear are added from 1.48.0, and a dedicated engine cockpit page shows the most important engine values at a glance. By swiping you swap the bar for further views: wind and compass rose, logbook and, for sailing boats, trim impact, trim advice and polars. The Plotter runs on board as soon as your app is connected to the Hub, without internet and without a subscription. As long as it is open, the screen stays on.
What you get
On board
- Instrument bar to your taste: You assign each tile an instrument of your choice. The same instrument may also appear several times.
- Suited to phone and tablet:
| Device and orientation | Layout | Assigned by default |
|---|---|---|
| Phone portrait | Bar at the top, 2 rows of 2 tiles each, collapsed to 1 row (from 1.48.0 also on the “Phone instruments” page) | Speed over ground, course over ground, apparent wind, heel |
| Phone landscape | Bar at the top, 1 row with up to 6 tiles | Speed over ground, course over ground, heading, apparent wind and wind angle, depth |
| Phone, “Phone instruments” page | 4 large tiles | Speed over ground, apparent wind angle, depth, supply voltage |
| Tablet portrait | Bar at the top, 1 to 3 rows of up to 6 tiles each | Speed, course, wind, depth; speed through water, ground wind, water temperature, air pressure, distance; waypoint, polar and voltage values |
| Tablet landscape | fixed row at the top and side bar with 4, 8 or 12 tiles | at the top as tablet portrait, in the side bar environment, boat and performance values |
- The 33 instruments in five groups, as they are called in the app, plus the engine instruments from 1.48.0 (see below):
| Group | Instruments |
|---|---|
| Navigation | Speed over ground, speed through water, course over ground, heading (true), rudder angle, distance travelled, distance to anchor, distance, expected duration and arrival to the next waypoint, course and bearing to the next waypoint, distance, expected duration and arrival to the last waypoint, time |
| Wind | apparent wind, apparent wind angle, ground wind speed, ground wind direction |
| Environmental Data | water depth, water temperature, air pressure, sea state |
| Boat | heel angle, leeway angle (angle between course over ground and heading), battery voltage, logbook status; from 1.48.0 also the “Engine” subgroup |
| Performance (sailing boats) | ratio of speed over ground to ground wind, velocity made good (VMG), polar performance, target speed and target VMG from the polar |
- Engine instruments (from 1.48.0): In the Boat group under “Engine” you find up to 18 values of your engine and gearbox:
| Area | Instruments |
|---|---|
| Engine | Engine speed, oil pressure, coolant temperature, oil temperature, alternator voltage, fuel consumption, engine load, engine hours (named this way from 1.48.1, short name “Eng. hours”), boost pressure, tilt / trim, fuel pressure, engine torque, coolant pressure, engine status |
| Gearbox | Gear, gearbox oil pressure, gearbox oil temperature, gearbox status |
- Which engine values you see: Only the values your engine actually sends are available to choose. The units: engine speed in rpm, pressures in bar, temperatures in your temperature unit, alternator in V, fuel consumption in l/h, engine load, torque and tilt / trim in %, engine hours in hours and minutes. The gear appears as “F” (forward), “N” (neutral) or “R” (reverse). Engine status and gearbox status show the warning your engine reports, or “No active engine warning” or “No active gearbox warning”. If you have several engines, the line under the short name says which engine is meant, for example “Port engine” and “Starboard engine” with two engines, otherwise “Engine 1”, “Engine 2” or the name you gave it under Onboard systems.
- Course and bearing to the next waypoint (separate from 1.48.0): “Course to Next Waypoint” (short name “CTW Next”) is the planned course of the current leg of your route, that is the direction of the course line from the start of the leg to the waypoint. The first leg starts where you docked the ruler to the boat. “Bearing to Waypoint” (short name “BTW”) is the direction from your current position to the waypoint. If you deviate from the course line, the two values differ. Both are true, that is relative to geographic north.
- Colour shows the side: Apparent wind angle and rudder angle show port in red and starboard in green, the rudder angle additionally with “Port” or “Stbd” after the value. The distance to the anchor is green inside your anchor circle and red outside. The battery symbol lights up when your battery alarm is switched on and flashes red during an alarm.
- Swipe pages: If you swipe in the bar, the view changes. The pages run in a circle:
| Page | What it shows |
|---|---|
| Instruments | your tiles |
| Phone instruments (phone only) | 4 large tiles |
| Engine cockpit (from 1.48.0, as soon as an engine sends data) | per engine a rev counter with gear and, if sent, engine load, plus two selectable main values with a small history and below them freely assignable engine tiles |
| Round instrument | Wind and compass rose with course over ground, heading, ground wind direction and a pointer for the apparent wind; in the middle you choose one of 7 values by swiping, for example depth or heel. On motorboats without the coloured sailing sectors and without heel, so with 6 values in the middle |
| Trim impact (sailing boats) | Speed over ground, apparent wind, speed against the wind and ratio to the ground wind as curves of the last 5 minutes |
| Trim advice (sailing boats) | see trim recommendations and trim impact |
| Polars (sailing boats) | your polar table, see polars and polar export |
| Logbook | the entries of the selected period |
| AIS target | appears as soon as you tap a vessel on the map |
| Measure distance | appears as soon as you open the ruler |
- For motorboats: If you have chosen “Motorboat” as the boat type under Boat configuration, the app hides the sailing views: trim impact, trim advice, polars and the five performance instruments. The app also shows the round instrument on motorboats, tailored to your boat: without the coloured sailing sectors and without heel in the middle. The wind instruments in the bar stay. Engine instruments and the engine cockpit are available on every boat whose engine sends data, so on sailing boats too.
- Engine cockpit (from 1.48.0): The page appears in the carousel directly after the instruments (on the phone after the phone instruments) as soon as the app knows an engine on your boat. It shows one or two engines side by side; if you have more, you choose the engine via the arrow next to the engine name. By default the rev counter goes up to 4,000 rpm, on motorboats up to 6,000 rpm, and grows by itself if your engine has already revved higher. You set a fixed upper limit under Onboard systems.
- Short ways: If you tap the Logbook Status tile, the logbook opens. The polar tiles open the polars, the Battery Voltage tile opens the supply voltage history with the setting for the battery alarm. An engine tile or the rev counter in the engine cockpit opens the history of that value for the selected period; for gear, engine status and gearbox status you see the changes with date and time instead.
- Every page remembers its size, for example a narrow instrument bar but a wide polar.
- Assignment per boat: If you sail several boats, you find your own assignment again on each.
- You also find the history and engine hours of each engine under Onboard systems.
- The map in the Plotter is covered in Chart and nautical charts, waypoints in Ruler and route planning.
Remotely
- There is a Plotter only on board. Whoever is not on board does not navigate. Remotely you see your boat in the Dashboard and in boat monitoring.
How it works
Opening the Plotter
- Connect your app to the Hub.
- The app opens the Plotter directly. Later you reach it via Menu › “Plotter”. When you connect to a new Hub for the very first time, the setup assistant runs first.
Swapping an instrument
- Tap the short name of a tile, for example “SOG”.
- Choose the group and then the instrument. Each row shows short and long name, the current instrument is marked with a tick.
- For an engine instrument with several engines, you also choose the engine.
- The tile changes immediately, and the app saves your choice automatically.
Using the engine cockpit (from 1.48.0)
- Swipe in the bar to the page with the rev counter.
- With several engines, tap the engine name under “Engine speed” and choose the engine.
- Tap the label of a main value next to the rev counter to choose a different engine value. By default these are fuel consumption and oil temperature.
- You assign the tiles below as in the instrument bar. By default: oil pressure, coolant temperature, alternator voltage, engine hours, oil temperature, fuel consumption, gear and engine speed. How many tiles you see depends on device, orientation and size of the bar.
- Tap the rev counter to open the RPM history.
Setting the upper limit of the rev counter
- Open Menu › “Onboard systems” and tap the slider icon next to “Engines”.
- In the “Configure engines” dialog, enter a value between 1 and 100,000 under “Maximum RPM”, or leave the field empty for “Automatic (leave blank)”.
- Tap “Save”.
Enlarging, reducing, collapsing the bar
- Bar at the top: Drag at the lower edge. It becomes at most half as tall as the screen. If you drag it very small, it collapses; a small tab expands it again. On the phone the instruments and, from 1.48.0, also the “Phone instruments” page then only show one row of 2 tiles.
- Side bar on a tablet in landscape: Drag at the edge. It snaps at 1, 2 or 3 columns of 4 tiles each.
Changing the view
- Swipe left or right in the bar. If you tap a vessel on the map or open the ruler, the matching page moves to the front by itself and afterwards back again.
Requirements
- Smartboatia Hub on board, app connected to the Hub.
- For the values the matching devices or sensors, for example an echo sounder for depth or a wind sensor for wind. Air pressure, heel, sea state and supply voltage are measured by the Hub itself.
- For the waypoint instruments a route from the ruler that is docked to the boat.
- For engine instruments and the engine cockpit (from 1.48.0): an engine that sends its data into the NMEA 2000 network, usually through an engine gateway, and the Hub on the same network. Your engine determines which values you get.
- For polar performance, target speed and target VMG (sailing boats): Your Hub is connected to the cloud and assigned to a boat. On board the app reads the polars directly from the Hub, even without internet.
- No internet needed, no subscription needed.
Permissions and subscription
- Subscription: The Plotter is fully usable without a subscription. With the Standard subscription the map in the Plotter also shows official nautical charts for selected regions, currently of the BSH for Germany and of NOAA for the USA (see Chart and nautical charts).
- On board: Everyone connected to the Hub uses and assigns the Plotter in the same way.
Safety notice
- Some values stay in place on failure. Most values go to dashes after a few seconds without data, the engine values too. Heel, sea state and rudder angle then keep showing the last value.
- No warning thresholds. The instruments do not warn, for example there is no shallow water warning on depth and no alarm for low oil pressure or high engine temperature. If your engine reports a warning, you only see it as text in the engine status, without sound and without push notification. Your engine’s own warning displays remain authoritative.
Notifications
None of their own. The Plotter only shows the state of other features: the flashing battery symbol for the battery alarm and the colour of the anchor distance for the anchor watch.

Offline behaviour
- The Plotter needs no internet. All values come live from the Hub, including the polars.
- After an app restart assignment and bar sizes are back. The bar starts on the first page again.
- The app remembers the engines of your boat. The engine cockpit therefore stays in the carousel even when the engine is switched off, and the values then show dashes.
- After a Hub restart or a short connection drop the values come back by themselves.
Frequently asked questions
How do I assign the instruments in the Plotter?
Tap the short name of a tile, for example "SOG", choose the group and then the instrument. The tile changes immediately, and the app saves your choice; 33 instruments are available, plus the engine instruments as soon as your engine sends data.
Do I need internet or a subscription for the Plotter?
No. The Plotter runs on board as soon as your app is connected to the Hub. With the Standard subscription the map in the Plotter also shows official nautical charts, currently of the BSH for Germany and of NOAA for the USA.
Why does an instrument show "-.-"?
No value is arriving from a sensor or device for it. For the values you need the matching devices, for example an echo sounder for depth or a wind sensor for wind; air pressure, heel, sea state and supply voltage are measured by the Hub itself.
Does the Plotter warn me about shallow water?
No. The instruments have no warning thresholds, including no shallow water warning on depth.
I have a motorboat. What changes?
If you choose the boat type "Motorboat" under Boat configuration, the app hides the views for sailing boats: trim impact, trim advice, polars and the five performance instruments. The round instrument stays, without the coloured sailing sectors and without heel. The wind instruments in the bar stay, and if your engine sends data, you get engine instruments and the engine cockpit.
Can I see RPM, oil pressure and engine temperature in the Plotter?
Yes, from version 1.48.0, as soon as your engine sends its data into the NMEA 2000 network and the Hub is on the same network. You choose the values as instruments in the Boat group under "Engine", and a dedicated engine cockpit page shows RPM, gear and the most important engine values at a glance.
What is the difference between course and bearing to the next waypoint?
The course is the planned direction of the current leg of your route, the bearing is the direction from your current position to the waypoint. If you have drifted off the course line, the two values differ.
Does the Plotter warn me about low oil pressure or a hot engine?
No. The engine instruments have no warning thresholds. If your engine itself reports a warning, it appears as text in the engine status, without sound and without push notification.
Can I also see the Plotter from home?
No, the Plotter is only available on board. Remotely you see your boat in the Dashboard and in boat monitoring.
