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
