Connected superyacht: GEST, OMNIYON, YIS and Nuvlock — four FSS products in a single vessel installation
A modern superyacht is one of the most demanding IoT environments: salt spray, vibration, steel bulkheads attenuating wireless signals, a mixed crew of 15, and guests paying €50,000+ per week who expect everything to work seamlessly.
The Four-Product Stack
- GEST — BLE service call buttons. Guest presses a button, the nearest crew member gets a smartphone notification within 2 seconds. 2-year coin cell battery life.
- OMNIYON — Unified A/V and comfort control. Netflix, Spotify, HVAC, motorised blinds from one app. WiFi 6 for 4K streaming.
- YIS — Vessel monitoring: engines, tanks, bilge pumps, AIS, GPS. 30-day local storage, syncs via Starlink.
- Nuvlock — Biometric + NFC + WiFi 6 access control. Check-in enrols guests in under 60 seconds.
Marine-Grade Engineering
All FSS marine hardware meets IEC 60945: -15°C to +55°C operating range, 95% RH, salt mist immunity. PCBs use conformal coating and marine-grade connectors throughout.
Networking Architecture Onboard
A superyacht’s network is more complex than most corporate offices. Multiple VLANs segregate guest WiFi, crew WiFi, vessel management systems, and IoT devices. OMNIYON, GEST, and YIS each operate on dedicated subnets with firewall rules controlling inter-VLAN traffic. Guest devices on the entertainment VLAN cannot reach vessel management systems under any circumstances — this is both a security and reliability requirement.
WiFi 6 (802.11ax) access points are placed throughout the vessel to provide full coverage — including below decks, where steel structure attenuates signals significantly. AP placement is planned using 3D vessel models and validated with a site survey before final installation. Mesh backhaul between APs uses dedicated 5GHz channels to avoid contention with guest traffic.
Remote Management and Diagnostics
When a vessel is at sea, there are no technicians available for on-site support. Every FSS product is designed for remote diagnostics: log streams accessible from the Azure dashboard, remote restart commands via IoT Hub direct methods, and automated anomaly detection that alerts the FSS support team before the crew notices a problem. In practice, we resolve 80% of fleet issues remotely without any interaction from vessel crew or management.
Firmware updates deploy automatically during scheduled maintenance windows — typically overnight when the vessel is at anchor and connectivity is stable. The crew wakes to updated, tested software. If an update fails the post-install validation, it rolls back automatically and generates an alert for engineering review.
Charter Guest Experience
Technology on a superyacht must be invisible when it works and immediately supportable when it does not. GEST, OMNIYON, and Nuvlock all provide a crew-facing tablet application that shows real-time status of every device — battery levels, last activity, network connectivity. A crew member without any technical background can identify a GEST button with a low battery, walk to its location, and replace the CR2032 cell in under a minute. This human factor design is as important as the underlying technology.
