Maritime connectivity: High-speed, uninterrupted internet on the open sea? It’s not just possible, it’s already happening.
In this case study, we explore how a luxury sea yacht achieved ultra-reliable, high-performance connectivity across continents using comBOX VLL (Virtual Leased Line). With dual Starlink terminals bonded into a virtual leased line, the vessel enjoys 500Mbps+ download and 100Mbps+ upload speeds, even while sailing in remote waters.
The Challenge: Consistent, High-Speed Internet at Sea
Modern yachts operate like floating offices and digital hubs. Whether for guests or crew, seamless connectivity is essential for:
- Streaming and video conferencing
- Real-time navigation and telemetry
- Monitoring onboard systems remotely
- Accessing cloud-based tools and services
- Ensuring zero downtime, even in beam transition zones
While Starlink offers fast global coverage, a single connection can still suffer from dropouts or instability. A more robust, bonded solution is required.
The comBOX VLL Solution: Redundant, Optimized Maritime Connectivity
To ensure unbreakable performance, the yacht was outfitted with:
- 2 x Starlink terminals, bonded for higher bandwidth and redundancy
- A comBOX multi-WAN router capable of aggregating multiple Internet links
- An LTE/5G router, seamlessly integrated and bonded with Starlink for added resilience during satellite beam transitions
- A comBOX VLL subscription, creating a high-speed Virtual Leased Line between the yacht and the Internet
- Intelligent TCP acceleration and WAN optimization for stable, real-time performance
Global Reach with Intelligent Traffic Routing
As the yacht sails across continents:
- In the Mediterranean (Summer) – traffic is routed via comBOX’s European Point of Presence (PoP)
- In the Caribbean (Winter) – traffic is routed via the Miami PoP
This location-aware routing ensures the lowest latency and best possible user experience, wherever the yacht may be.
Enhanced Reliability with Public IPs and Smart Failover
Beyond raw speed, comBOX VLL provides a suite of enterprise-grade features, including:
- Transparent failover between Starlink and LTE/5G, maintaining stable sessions during link degradation or handoffs
- Public static IP addresses, allowing remote access to the yacht’s onboard information systems for monitoring, maintenance, and control
- Advanced WAN optimization, boosting the performance of bandwidth-sensitive and real-time applications
- Real-time monitoring via a centralized web GUI for full control from shore
The Result
- 500Mbps+ bonded download / 100Mbps+ upload
- Remote access with static IPs
- Global routing logic via comBOX PoPs
- No disruption during Starlink beam transitions
- LTE/5G backup for added redundancy
- Flawless connectivity and cloud access
Bring Enterprise Connectivity to Your Yacht
Whether you’re crossing the Atlantic or docked in Saint-Tropez, comBOX VLL ensures your vessel stays connected, reliably, securely, and at top speed.
