VANEMAR / FREQUENTLY ASKED QUESTIONS

The adapter connects your boat's NMEA 2000 network to Vanemar. It reads supported data from the equipment on that network and sends it wirelessly to your Gateway, so you can see it in the app.

Use it to bring compatible engine, tank, battery, wind and depth readings into the same place as your other boat information.

Depending on your onboard equipment, you can see readings such as engine RPM and hours, fuel and other tank levels, battery voltage and charging information, wind speed, water depth and digital switching data.

Your equipment must send the relevant information to the NMEA 2000 network. For example, to see a tank level, you need a compatible tank sensor that supplies that reading. Check your equipment with our support team if you are planning around a particular measurement.

Check your boat's equipment manuals or electrical diagram for NMEA 2000 connections. You may find a network backbone with T-connectors linking equipment such as engine displays and chartplotters.

If you are unsure, send our support team the equipment models and photos of the connections, or ask your marine electrician. Confirm compatibility before ordering the adapter.

Follow the installation guide to connect the adapter to your boat's existing NMEA 2000 network using the supplied connection cable and T-connector. It takes power from that network, so it does not need a separate power connection.

The adapter sends data wirelessly to your Gateway. Once connected, complete the setup in the Vanemar app and check that your equipment readings appear.

Yes, if your boat has a compatible digital switching system on its NMEA 2000 network. Connect the Vanemar NMEA 2000 Adapter to bring supported switches into the app, then use them to control the connected circuits.

You need a Gateway, the adapter and compatible switching equipment aboard. You can enable biometric authentication for an extra check before a switching command. Review the circuit labels and setup with your installer before using remote controls.

Yes. With a compatible tank-level source on your NMEA 2000 network and the Vanemar adapter, set a minimum or maximum warning level for each tank in the app.

For example, set a low-level warning for fuel or fresh water and a high-level warning for a waste tank. Choose thresholds that give you time to act and check that each tank is named correctly.

Yes, when compatible equipment supplies those measurements over NMEA 2000. With the Vanemar adapter, you can view available AC input and output data, including voltage, current, frequency and power.

The readings you see depend on your onboard equipment and software compatibility. A Smart Plug shore-power alert detects a loss of the plug’s connection; use a compatible NMEA data source when you need electrical measurements.

Use the Vanemar app to arm your boat's security system when you leave and disarm it when you return. For example, the Motion Sensor sends movement alerts while the system is armed.

Before leaving, check the security status in the app and make sure the relevant sensors are connected. Disarm the system when you or your crew are back on board.

Yes. Switch to Onboard mode when you are using the boat. This stops normal movement and door activity from triggering intrusion alarms.

Critical monitoring, such as smoke, carbon monoxide, high bilge water and battery alerts, remains active according to your installed devices and settings. Check those settings when you set up the system, and switch back to Armed mode when you leave.

Use geofence protection to receive an alert if your boat moves outside the boundary you set. Check that the app shows the boat’s current position, then adjust the radius to suit its berth or anchorage.

Allow room for normal movement around a mooring or anchor. Review the boundary and security mode when you leave the boat so that protection matches where you are.

First, check the position shown in the app. A restricted view of the sky or nearby metal can affect GPS reception. Follow the antenna placement guide and check its connection.

If the position looks right, review your geofence radius. A radius that is too small can trigger alerts during normal movement around a mooring. Allow for that movement, then test the new setting before leaving the boat.

For critical alerts, Vanemar sends an app notification and starts an automatic phone call if the alert has not been seen within 60 seconds.

Keep your Connect subscription active and check your contact and notification settings during setup. The Gateway needs a working connection to send the alert.

Yes. Open Notification Settings in the Vanemar app and choose the updates you want. You can manage alerts, connection status, power and battery updates, sensor connections, temperature, humidity, tank levels and engine notifications separately.

Review these settings after adding equipment so the notifications match what you want to monitor.

Yes. In Notification Settings, choose All Boats to apply a preference to every boat in your account, including boats you add later.

If you want it to apply only to certain boats, choose Selected Boats and select those boats.

No. Muting alerts pauses new notifications; the sensor keeps monitoring and any existing alarm state remains visible. Use this when you are already dealing with an issue or carrying out maintenance.

Choose a set time or mute alerts until you turn them back on. If you choose a time limit, notifications resume automatically when it ends.

1. Check that your Gateway is online and Connect is active.
2. Allow notifications from Vanemar in your phone's settings.
3. Make sure the notification you expect is enabled in the app.
4. Check whether alerts from the sensor are muted.
5. For entry or motion alerts, check that the security system is armed.

If you still do not receive the alert, check our service status and contact support with the sensor name, event and time it happened.

Yes, with a compatible multifunction display and a Vanemar NMEA 2000 Adapter. Enable forwarding in the app to send supported alarms and warnings to the display.

You can choose alarm and warning types separately. Check display compatibility and test the settings aboard before relying on them during a trip.

Yes. With Connect, look back at your boat’s location, journeys, recorded alerts and available sensor readings in the Vanemar app. If you use the NMEA 2000 Adapter, you can also review the history of supported engine, tank and battery measurements.

Choose a date or period to see what happened and how readings changed. The history depends on what your installed sensors and onboard equipment recorded.

The Gateway model linked below has a tamper sensor that checks its distance from the mounting surface. It can raise an alert if it detects that the device has been disturbed.

Mount it securely as shown in the installation guide. Keep Connect active and the Gateway connected so you can receive the alert while you are away.

Yes. Use the sharing options in the Vanemar app to give your family, captain or crew access to your boat. With Connect, there is no extra charge per shared user.

Manage access from your own account so the people you choose can keep an eye on the boat too.

Open Boat Settings → Users, choose Add User or the + button, enter their email address and send the invitation.

They do not need an account before you invite them. Ask them to sign in or register with the same email address and accept the invitation. A pending invitation does not give access until it is accepted.

Sign in to the Vanemar app using the email address that received the invitation. If you are new to Vanemar, create your account with that address first.

Open the invitation notification, or find the boat marked Waiting for acceptance in Settings, then choose Accept. If you cannot see it, check which email address the owner used and ask them to resend the invitation if needed.

Yes. As the boat owner, open Boat Settings → Users and select the person. Choose Revoke Access to remove an accepted user, or Cancel Invitation if the invitation is still pending.

This changes access for that person only. Review the list when your captain, crew or other people looking after the boat change.

Yes. As the current owner, open Boat Settings → Transfer Boat, enter the buyer’s email address, choose whether to include history and send the request. They can accept ownership without reinstalling the existing system.

Once they accept, access is removed for you and all previously added users. Existing Connect and other boat subscriptions are cancelled, so the new owner needs to arrange their own subscription and invite their users. A pending transfer expires after 30 days; you can cancel or resend it before acceptance.

Choose Include History if you want the new owner to receive the boat’s recorded data, such as location, battery, temperature and humidity history.

If you turn this option off, the previous history is permanently deleted when the transfer is completed. You cannot undo that deletion, so review your choice before sending the transfer request.

If you run a charter company, fishing fleet or workboat operation, Vanemar Fleet helps you keep track of your boats and make daily operating decisions from one place.

Choose shared access when your family or captain needs to keep an eye on your boat. Consider Fleet when you need to coordinate a business: decide where your team is needed, prepare boats for their next job and use operating data to improve costs and availability.

Yes. Use Vanemar Fleet Management to follow your vessels and manage crew access from one dashboard on mobile or desktop, including boats operating from different bases. You can add as many boats and crew members as your operation needs.

Plan a Gateway and the right monitoring equipment for each vessel, then contact our team to discuss fleet setup and subscriptions. Your dashboard brings together location, vessel status and the operating data available from each boat.

Yes. Add the people who look after your fleet so they can work from the same view of your boats. Agree who checks alerts, who contacts the crew and who arranges maintenance.

Keep the user list current when staff responsibilities change. Before rollout, discuss your team’s access needs with us so the setup fits the way you operate.

Yes. Create the permitted and restricted areas you need in Fleet Management and receive alerts when a vessel crosses a boundary.

Use these alerts to follow up with your skipper or crew when a boat leaves its permitted area or enters a restricted one. They help you monitor operations but do not control the vessel's movement.

Before the next handover, review the boat’s available battery, bilge, shore-power and other status data. Use recent alerts and journey information to decide which checks your turnaround team should tackle first.

This helps you prepare for a problem before the next guest arrives and reduce avoidable delays. Keep your physical handover and safety checks as part of the routine.

Yes. Start with a small group that represents your boat types, engines and operating bases. Choose the questions you want the trial to answer, such as where fuel is being wasted or how quickly your team can respond to alerts.

Check installation, coverage and data quality, then agree a practical routine with the staff using it. Use what you learn to plan the rest of the fleet and any additional sensors or NMEA connections.

See where the fuel is going before deciding what to change. Review consumption alongside journeys, speed, engine RPM and time spent operating. You can then spot avoidable running time, compare cruising habits and investigate boats that use more fuel than expected.

Use those findings to adjust operating routines and brief your crews. The savings depend on how your fleet is used and the changes you make; fuel analysis requires compatible onboard fuel data.

Litres per hour (L/h) helps you understand how quickly fuel is being used while operating. Litres per nautical mile (L/nm) helps you compare how much fuel it takes to cover a distance.

Use both where compatible data is available. A lower hourly burn does not necessarily mean a more economical journey if the boat covers much less distance. Compare similar operating conditions and review the whole trip before drawing a conclusion.

Review engine use alongside journey time, position, speed and available fuel readings. Look for periods when an engine is running but the boat is making little progress, then check the reason with the crew.

Some running time is necessary for manoeuvring or the job aboard. Focus on avoidable waiting and operating habits you can change safely. A stationary position on its own does not prove that an engine was idling.

When enough compatible engine, speed and fuel data is available, Vanemar Smart Data uses the boat’s own operating history to identify efficient cruising ranges. Review RPM, speed and fuel per nautical mile together to see where that boat tends to run efficiently.

You can also see how much operating time falls into efficient, transition or high-consumption ranges. Use this to brief your crew while allowing for weather, load, sea conditions and safe navigation.

Start with boats doing similar work. Compare the route, distance, engine hours, speed and fuel use, and account for differences in load, weather and sea conditions. Where enough data exists, Smart Data can also compare boats using the same engine model and flag unusual consumption.

Check an outlier before deciding what caused it. Hull condition, operating habits and mechanical issues can all affect consumption; a higher figure alone does not identify the cause.

Use available engine readings, alerts and changes in performance to spot issues that deserve attention early. A boat consuming more fuel than usual or showing unusual engine data gives your team a reason to check it before the problem disrupts operations.

Timely checks can help reduce avoidable damage, urgent repairs and downtime. Smart Data helps you decide which boat to inspect first; it does not diagnose faults or replace the engine manufacturer’s service procedures.

Yes, when your connected engine system provides engine-hour data. Review the hours for each boat and compare them with its last service record and the manufacturer’s time- and hour-based service intervals.

Plan the work around bookings or quieter operating periods where possible. Keep a service record and follow the required maintenance schedule even when the boat’s readings look normal.

Compare engine hours, journey time, distance and operating periods across your fleet. Look for boats carrying most of the workload and others that are used less often.

Use that picture when assigning boats, planning staff coverage and scheduling maintenance. Balance the workload where it makes sense for each boat’s capacity and role, so you can get more value from the fleet and avoid unnecessary downtime.

Use journey history to review the route, duration and distance of completed trips. Heatmaps help you see frequently used areas and places where boats spend time.

Discuss repeated detours, long waits or busy locations with your crews. Use what you learn to adjust schedules, departure routines or routes where appropriate. You make the operating decisions; the data helps you see where to look.

Each result depends on the data available from that boat. Fuel analysis needs compatible fuel readings; efficient cruising analysis also needs enough useful engine and speed history. A new installation or incomplete data may not yet support a meaningful result.

Check the connected equipment, NMEA sources and connection status. Allow enough representative journeys to build a history, and ask Support to review the setup if expected readings are still missing.

Record a baseline before changing your operating routine. Compare similar periods using fuel per journey or distance, engine hours, maintenance spending and time out of service. Note changes in workload, fuel prices, weather and boat condition so the comparison is fair.

After you act on the data, review the same measures again. Combine the Vanemar figures with your own fuel invoices and service records to see what has improved and where to focus next. There is no single savings percentage or payback period that fits every fleet.

Battery life depends on the sensor and how it is used. As a guide, expect around 2 years for the Motion Sensor, up to 3 years for the Entry Sensor and up to 5 years for the Smoke Detector.

Watch for low-battery alerts in the app and use the battery type listed in the sensor's manual. The Smoke Detector also gives an audible low-battery warning. Your Battery Sensor takes power from the boat battery it monitors, so it has no separate battery to replace.

Test your Smoke Detector monthly with its test button. Check for low-battery alerts and disconnected sensors in the app, and follow the care instructions for each device.

After moving equipment or changing your boat's wiring, check the affected sensors and readings again. If you use the NMEA 2000 Adapter, confirm that your connected equipment is still sending data to the app.

First, check whether the Gateway is online. If all sensors appear unavailable, start with the Gateway’s power and connection. If only one sensor is affected, check its battery or power supply and whether anything has changed around its position.

Metal partitions and distance can affect the wireless connection. Follow that sensor’s troubleshooting guide and contact Support with its name, model and the time the connection was lost if it does not reconnect.
