- INTRODUCTION & PROJECT OVERVIEW ============================================================
This article documents a professional installation project involving two luxury yachts: an Ocean Alexander 32E and a Princess Y72. The scope included complete networking infrastructure, audio-visual systems, and satellite connectivity for both vessels.
PROJECT SCOPE
- Ocean Alexander 32E: Retrofit from factory-installed systems
- Princess Y72: New installation on delivery
Both vessels required:
- Enterprise-grade networking with UniFi equipment
- Full Control4 AV integration (audio, video, lighting, shades)
- Dual Starlink satellite connectivity per vessel
- Marine-rated equipment and proper weatherproofing
- Network segmentation for crew, guests, and IoT devices
The unique challenge of this project was implementing a dual-Starlink strategy per yacht that optimizes both cost and coverage across different operating scenarios - US coastal cruising versus international or open-ocean voyaging.
============================================================ 2. THE VESSELS
OCEAN ALEXANDER 32E
The Ocean Alexander 32E is a luxury explorer yacht stretching approximately 100 feet in length. Known for its robust construction and long-range cruising capabilities, the 32E presented unique retrofit challenges:
- Factory-installed networking was consumer-grade and inadequate
- Existing cable runs needed to be traced and evaluated
- Some equipment locations required relocation for optimal coverage
- Integration with existing onboard systems (NMEA 2000, etc.)
The explorer yacht design, with multiple decks and heavy steel construction, created interesting RF propagation challenges that required careful access point placement.
PRINCESS Y72
The Princess Y72 is a 72-foot motor yacht from the renowned British manufacturer. As a new installation, we had the advantage of planning cable runs and equipment locations from the start:
- Clean slate for network infrastructure design
- Coordination with shipyard during commissioning
- Optimal equipment placement without retrofit constraints
- Integration planning during the build process
Both vessels, despite their size difference, required similar solutions and equipment configurations. The installation approach was standardized to maintain consistency and simplify future maintenance and support.
============================================================ 3. DUAL-STARLINK CONFIGURATION STRATEGY
One of the most innovative aspects of this installation was the dual-Starlink per vessel strategy. Each yacht has TWO Starlink terminals with different service plans optimized for different operating scenarios.
TERMINAL 1: STANDARD STARLINK WITH ROAM PLAN
The first terminal uses a standard residential Starlink dish with the Roam plan activated:
Purpose:
- US coastal and inland waterway cruising
- Stateside marina stays
- Primary internet when within US coverage
Advantages:
- Significantly lower monthly cost than maritime plans
- Unlimited data with Roam plan
- Excellent performance in US waters
- Portable between locations
The Roam plan allows the dish to be used anywhere within the US service area, making it perfect for coastal cruising from Florida to New England or Pacific Coast routes.
TERMINAL 2: MARITIME STARLINK WITH GLOBAL PRIORITY
The second terminal uses a proper maritime-rated Starlink dish with Global Priority service:
Purpose:
- International waters and ocean crossings
- Outside US coverage areas (Caribbean, Mediterranean, etc.)
- Backup connectivity when primary fails
- Priority data allocation
Advantages:
- True global coverage including open ocean
- Maritime-rated hardware for harsh conditions
- Priority network access for consistent speeds
- In-motion capability at higher speeds
FAILOVER CONFIGURATION
The UniFi Dream Machine Pro manages both Starlink connections using multi-WAN load balancing:
Primary WAN: Standard Starlink (when in US waters) Secondary WAN: Maritime Starlink (failover or primary internationally)
The failover logic is configured to:
- Prefer the lower-cost Roam terminal when viable
- Automatically switch to Maritime when Roam loses connectivity
- Load balance across both for maximum throughput when appropriate
- Allow manual override via UniFi dashboard for specific scenarios
COST OPTIMIZATION
This dual-terminal approach saves significant money compared to running Maritime Global Priority full-time:
- Maritime Priority: High monthly cost, always-on global coverage
- Roam Plan: Fraction of the cost for US coverage
- Result: Maritime costs only apply when actually needed
For vessels that spend 80% of their time in US waters with occasional international trips, this strategy can reduce annual connectivity costs substantially.
MOUNTING CONSIDERATIONS
Installing two Starlink dishes per vessel required careful planning:
Location Selection:
- Clear view of northern sky (for LEO satellite visibility)
- Minimal obstruction from masts, antennas, and radar equipment
- Adequate separation between dishes to prevent interference
- Protected from direct wave impact and salt spray
Mounting Hardware:
- Marine-grade stainless steel mounting brackets
- Vibration dampening to prevent dish movement
- Secure cable routing through weatherproof penetrations
- Accessible for maintenance without scaffold/lift
Both dishes are mounted on the upper deck/flybridge area with custom fabricated brackets designed for each vessel's specific superstructure geometry.
============================================================ 4. UNIFI NETWORK INFRASTRUCTURE
The network backbone for both vessels is built on Ubiquiti's UniFi ecosystem, chosen for its enterprise features, central management, and excellent value proposition.
DREAM MACHINE PRO (UDM-PRO)
The UDM-Pro serves as the network core:
- Router/firewall with IDS/IPS capability
- UniFi Network application for device management
- Multi-WAN support for dual Starlink configuration
- 10Gbps SFP+ ports for future expansion
- Built-in 8-port gigabit switch
The UDM-Pro is installed in a climate-controlled equipment room with proper ventilation. Marine environments are harsh on electronics, so maintaining appropriate temperature and humidity is critical.
REDUNDANT POWER SUPPLY (RPS)
Network uptime is critical on a vessel where connectivity may be the only link to emergency services or weather updates. The UniFi RPS provides:
- Automatic failover if primary power fails
- Battery backup for graceful shutdown
- Notification alerts for power issues
- Peace of mind during generator switchovers
The RPS is particularly important during anchor or marina stays where shore power connections can be unstable.
ACCESS POINTS
WiFi coverage throughout both vessels is provided by UniFi U6/U7 series access points:
Interior APs:
- Salon/main living areas
- Staterooms
- Galley and crew quarters
- Engine room (yes, even there)
Exterior APs:
- Flybridge
- Aft deck
- Bow area
Placement was determined through site surveys considering:
- Steel bulkheads that block RF signals
- High-traffic areas requiring capacity
- Guest vs crew coverage separation
- Outdoor areas where guests congregate
Each vessel has 6-8 access points depending on layout, all powered via PoE from the central switches.
POE SWITCHES
UniFi PoE switches distribute power and data throughout the vessel:
- 24-port and 16-port models depending on location
- PoE+ for higher-power devices
- Managed switching with VLAN support
- SFP uplinks for backbone connections
Switches are installed in distribution points throughout each deck, minimizing cable run lengths while maintaining proper network topology.
============================================================ 5. VLAN ARCHITECTURE & NETWORK SEGMENTATION
Proper network segmentation is critical for both security and performance. The VLAN architecture separates traffic into distinct broadcast domains:
VLAN 1 - MANAGEMENT (Native)
- UniFi devices
- Network infrastructure
- Administrative access only
- Isolated from all guest traffic
VLAN 10 - CREW
- Crew personal devices
- Crew workstations
- Internal communications
- Access to onboard systems
- Internet access
VLAN 20 - GUEST
- Guest personal devices
- Captive portal capability
- Internet access only
- No access to internal systems
- Bandwidth limits applied
VLAN 30 - IOT/CONTROL4
- Control4 controllers and devices
- Audio/video equipment
- Lighting controls
- HVAC integration
- Shade controls
- Isolated from direct internet access
VLAN 40 - SECURITY
- UniFi Protect cameras (if installed)

INTER-VLAN ROUTING
Firewall rules control traffic between VLANs:
- Management can access all VLANs
- Crew can access IoT for control purposes
- Guest has no inter-VLAN access
- IoT devices cannot initiate outbound internet
This segmentation ensures that:
- Guest devices cannot access AV systems directly
- IoT devices are isolated from the internet
- Compromised devices cannot traverse networks
- Management access is properly secured
============================================================ 6. CONTROL4 AV SYSTEM INTEGRATION

============================================================ 7. MARINE ENVIRONMENT CHALLENGES
Installing technology on vessels presents unique challenges that land-based installations never encounter.
CORROSION RESISTANCE
Salt air is incredibly corrosive to electronics:
Equipment Selection:
- Marine-rated products where available
- Conformal coating on exposed circuit boards
- Stainless steel hardware only
- Proper drainage for any water intrusion
Installation Practices:
- Sealed cable penetrations
- Drip loops on all cable runs
- Gore-Tex vent plugs for pressure equalization
- Regular inspection and maintenance schedule
MARINE-RATED ENCLOSURES
Not all networking equipment comes in marine versions:
Solutions:
- NEMA 4X enclosures for distribution points
- Climate-controlled equipment rooms
- Desiccant packs in sealed enclosures
- Positive pressure ventilation where possible
The UDM-Pro and core switches reside in climate-controlled spaces, but distribution equipment throughout the vessel requires proper protection.
WATERPROOFING
Even interior spaces can experience moisture:
Strategies:
- IP-rated equipment where exposed
- Sealed cable glands at all penetrations
- Sloped mounting to prevent pooling
- Inspection ports for periodic checks
Exterior installations (access points, speakers, cameras) require careful attention to mounting orientation and drainage.
VIBRATION AND MOVEMENT
Vessels move constantly, creating stress on:
- Cable connections (use strain relief everywhere)
- Equipment mounting (secure but vibration-dampened)
- Antenna alignment (gimbal mounts for Starlink)
- Rack-mounted equipment (proper rail systems)
All equipment is mounted with appropriate vibration dampening, and cable runs include service loops to accommodate movement.
POWER QUALITY
Marine electrical systems can be challenging:
Issues:
- Voltage fluctuations during generator switchover
- Inverter-generated power (modified vs pure sine wave)
- Shore power variations across marinas
- Lightning and surge risks
Solutions:
- UPS/battery backup for critical equipment
- Surge protection at key distribution points
- Power conditioning where necessary
- Proper grounding (challenging on a vessel!)
============================================================ 8. CABLE ROUTING & INFRASTRUCTURE
Running cables through a yacht is vastly different from a building installation.
EXISTING PATHWAYS
On the retrofit (OA 32E), we worked with existing pathways:
- Traced factory-installed conduit runs
- Identified accessible cable chases
- Worked with naval architect drawings
- Minimized new penetrations
On the new installation (Princess Y72), pathways were planned during commissioning with shipyard coordination.
CABLE TYPES
Different cable types for different purposes:
Data:
- Cat6A shielded for backbone runs
- Cat6 for shorter runs to endpoints
- Fiber for longest runs (noise immunity)
Audio/Video:
- HDBaseT cabling to displays
- Speaker wire (marine-rated jacket)
- Control wiring to keypads
Power:
- Properly sized for PoE loads
- Marine-rated jacket material
- Separate from data where possible
PENETRATIONS
Every penetration through a bulkhead is a potential leak point:
Best Practices:
- Minimize penetrations
- Use proper marine-grade cable glands
- Seal with appropriate marine sealant
- Document all penetrations for future reference
- Test for water intrusion after installation
LABELING AND DOCUMENTATION
Marine installations require excellent documentation:
- Every cable labeled at both ends
- Cable schedule with run lengths and purposes
- Network diagram posted in equipment room
- As-built drawings for future reference
Future technicians (or yourself) will thank you when troubleshooting is needed.
============================================================ 9. CONTROL4 + UNIFI INTEGRATION DETAILS
Getting Control4 and UniFi to work together seamlessly required attention to several technical details.
MDNS/BONJOUR
Control4 devices rely heavily on mDNS for discovery:
Configuration:
- Enable mDNS reflector on UDM-Pro
- Configure mDNS to cross VLAN boundaries (selectively)
- Allow Control4 app discovery from guest VLAN
- Block unnecessary mDNS traffic
Without proper mDNS configuration, Control4 apps on guest devices cannot discover the controllers.
IGMP SNOOPING
Multicast traffic is important for:
- Audio streaming between zones
- Video distribution
- Control4 device communication
IGMP Configuration:
- Enable IGMP snooping on all VLANs
- Configure IGMP querier on UDM-Pro
- Set appropriate group membership timeouts
- Test multicast routing between VLANs
STATIC IP ASSIGNMENTS
All Control4 devices receive static IPs via DHCP reservation:
- Controllers
- Touch panels
- Audio endpoints
- Network-connected sources
This ensures consistent addressing and simplifies firewall rules and troubleshooting.
FIREWALL RULES
Specific rules allow Control4 traffic while maintaining security:
Allow:
- Control4 app access from guest VLAN to IoT VLAN
- Controller communication between VLANs
- Remote access via Control4 cloud (outbound only)
Block:
- Direct IoT device internet access
- Inter-device communication across VLANs (unless required)
- Guest access to admin interfaces
QOS CONFIGURATION
Quality of Service ensures AV traffic receives priority:
- Audio streams: High priority
- Video streams: High priority
- Control traffic: Medium priority
- General data: Best effort
This prevents guest downloads from impacting AV performance.
============================================================ 10. LESSONS LEARNED & RECOMMENDATIONS
STARLINK MOUNTING
Lesson: Initial mounting locations looked good but had partial sky obstructions from radar and antenna masts.
Recommendation:
- Use Starlink app's obstruction checker before finalizing
- Test at different vessel orientations (swing at anchor)
- Plan for multiple Starlinks with adequate separation
- Consider dedicated mounting platform for clean sightlines
NETWORK VLAN SETUP
Lesson: Initial guest network was too restrictive, preventing some smart devices (phones controlling AV) from functioning.
Recommendation:
- Test all use cases before finalizing firewall rules
- Allow specific paths for control apps
- Document all inter-VLAN rules with justification
- Plan for guest devices that need IoT access
CONTROL4 + UNIFI
Lesson: Default UniFi settings blocked mDNS between VLANs, breaking Control4 app discovery completely.
Recommendation:
- Test Control4 app from all VLANs before commissioning
- Configure mDNS reflector early in setup
- Document required multicast traffic
- Have Control4 programmer test from guest network
MARINE-RATED GEAR
Lesson: Some "marine-rated" equipment still failed due to inadequate corrosion protection in tropical conditions.
Recommendation:
- Research actual marine installations, not just ratings
- Apply additional protection (conformal coating)
- Plan for equipment replacement cycles
- Maintain spare parts inventory
CABLE ROUTING
Lesson: What looks accessible with panels open may be impossible to reach once the vessel is operational.
Recommendation:
- Document EVERYTHING during open-panel access
- Install pull strings for future cables
- Take photos of every cable pathway
- Test all drops before closing up
