On board or from ashore
See vessel data wherever you are
Monitor the vessel's position, battery status, tanks, engines, bilge level, shore power and other connected systems through the onboard dashboard, web app or mobile app.
Integrated smart vessel platform
One system. Total control. Anytime. Anywhere.
Nautech brings existing onboard systems into one connected platform for live vessel data, remote control and automation, across a single vessel or an entire fleet.
Brand-agnostic by design, it integrates technologies across different manufacturers and networks without locking operators into a single ecosystem.

- AutomationConfigurable rules, alarms and coordinated responses

Platform capabilities
Monitor, control and respond wherever the vessel is
Digital switching
Control configured onboard systems
Control connected lights, pumps and other configured loads from the app or dashboard. Use pre-configured rule sets for harbour, coastal or offshore operation.
Alarms and automation
Respond when conditions change
Set alarm thresholds for connected values and notify the relevant people when an event occurs. Where configured, automation rules can activate a relay, isolate a load or record camera footage around the event.
Alarms and automation
Beyond monitoring: from awareness to action
Set thresholds for the values that matter, such as low battery voltage, high bilge level, loss of shore power or high coolant temperature. Nautech Core monitors connected systems on board, evaluates events even without mobile coverage and can alert designated users or trigger a configured response.
Continuous monitoring
Define upper and lower thresholds for connected values. Built-in hysteresis prevents repeated alerts caused by normal fluctuations, while alarm states and event history are recorded and available for review.
Automated response
A rule can activate a configured relay, isolate a load or record camera footage around an event. Presets provide pre-configured rule sets for harbour, coastal or offshore operation.
Geofence monitoring
Create geofences around a berth, marina or other defined area. Entry, exit and proximity events are evaluated on board and logged with position and time.
Role-based notifications
Assign owners, skippers, technicians or operators to the relevant vessels. Each person receives the vessel data and notifications relevant to their role.
Apps
One platform, on your phone and in your browser
The mobile app and web dashboard use the same live and historical vessel data. Settings, alarms, automation rules and access permissions remain consistent from a single-vessel view to fleet-wide oversight.
Mobile app
On Android and iOS, view live vessel data, map position, alarms, routes, digital switching and onboard cameras. Receive push notifications, review active and resolved alarms and use red night mode at the helm.
- Live RTSP video from onboard cameras
- Digital switching with presets
- Last received vessel data remains available offline
- Home screen widget on iOS
- Available in ten languages
Explore the mobile app preview.
Web dashboard
Sign in at dashboard.nautech.cloud from any browser or install the web app. Arrange live values as cards, gauges and charts, customise the grid and see alarm states at a glance.
- Cards, gauges and history charts
- Notifications, switches, cameras and routes
- Light, dark and auto themes
- HMI panel with live values on your own drawing
Explore the pages, charts, switches and map in the interactive preview.

This interactive preview uses an example vessel and simulated data. It demonstrates the dashboard layout and selected functions; nothing shown here controls a real vessel. The working application is available at dashboard.nautech.cloud.
From one vessel to the entire fleet
Charter operators, marinas and fleet managers can view vessel positions, connectivity, open alarms, switches and cameras on one screen. Assign users by vessel and role, from individual access to fleet-wide oversight.
Night Watch mode
Designed for use after dark
Switch to Night Watch mode for a low-light interface designed for onboard use at night, while keeping the same familiar layout.
- Light, dark and Night Watch modes
- Switch between display modes manually
How it works
One connected system, from vessel to screen
Aboard
Nautech Core connects to the vessel's NMEA 2000 backbone and compatible NMEA 0183 and IP-based systems. It reads connected data and records it locally before synchronising with the cloud.
Cloud
Over 4G, Nautech Core synchronises live data, history, alarms, automation rules, geofences and user permissions with Nautech Cloud.
Anywhere
Authorised users access the same live data, history, alarms and configured controls through the mobile app, web dashboard or fleet view.

Alarms, geofences and configured automation rules are evaluated on board, so essential responses continue when mobile coverage is unavailable.
Open architecture: Nautech Core works with NMEA 2000, NMEA 0183 and compatible IP-based systems, allowing compatible existing onboard equipment to be integrated. Additional modules and vessels can be added as requirements grow.
Routes and logbook
Every journey, automatically recorded
Nautech Core records vessel position while the vessel is moving, building route and trip history without requiring anyone to start a stopwatch. Review recorded tracks and previous passages together with duration, distance and available operating data.
Hardware
Three core configurations
All three configurations use the same IP68 housing and Nautech Cloud platform. They differ in onboard interfaces, digital-switching capabilities and support for advanced integrations.
Sealed Gigabit Ethernet
NMEA 2000 backbone

Passively cooled IP68 aluminium housing
Flanges for a bulkhead mount
core

Solutions
One platform for different marine operations
Configure Nautech around an individual yacht, charter fleet, fishing vessel, ferry or offshore workboat. The platform adapts to the vessel, operation and people responsible for it.
Charter operators and fleet managers
Monitor vessel positions, connectivity, system status, alarms, cameras and history from one place. Real-time information helps teams reduce manual checks, identify issues earlier and improve maintenance planning, vessel turnaround and fleet availability.
Distributors
A scalable platform that works with equipment already in your portfolio, supports retrofit and new-build projects and creates opportunities for cross-selling and ongoing technical services.
System integrators
Integrate existing NMEA, communication and power systems, then use remote access and diagnostics to support customers without unnecessary visits to the vessel.
