Security Systems

What are yacht security systems?

Yacht security systems are the layered combination of hardware, software and procedure that protects a superyacht, its owner, guests and crew across four overlapping domains: physical access, surveillance, perimeter protection and cybersecurity. On a modern 50m+ yacht they are designed and installed as a single integrated package, typically by a specialist AV/IT and security integrator working alongside the build yard or refit yard.

Physical access covers boarding control at the passerelle and tender platform, electronic or biometric locks on the owner's suite and senior cabins, in-cabin safes, and segregated crew and service routes that keep guest areas private. Surveillance is built around a CCTV network covering every deck, exterior approach and engine-room space, with PTZ and ultra-HD long-range cameras at the bow, stern and bridge wings and thermal imaging cameras that maintain visibility at night without deck lighting.

Perimeter protection adds non-lethal deterrents on yachts operating in higher-risk waters: Long Range Acoustic Devices (LRAD) broadcast pain-inducing sound and multilingual warnings out to three kilometres, water cannons cover the waterline, and citadel-style safe rooms are specified on owners' yachts transiting the Gulf of Aden, West Africa or parts of South-east Asia. Cybersecurity is the newer, less visible layer: segmented networks isolate the bridge, owner, guest and crew Wi-Fi from one another, navigation and OT systems sit behind separate firewalls.

Procedure binds the four layers together. For commercial yachts at or above 500 GT trading internationally, the ISPS Code under SOLAS Chapter XI-2 mandates a Ship Security Plan, a designated Ship Security Officer and an International Ship Security Certificate (ISSC).

Why it matters for yacht owners

For HNWI owners, the value of a well-designed security system is discretion rather than display. Effective surveillance and access control let an owner host openly on deck without being photographed from a tender at the perimeter, keep the owner's suite genuinely private from rotating crew and contractors, and move between yacht and shore without exposing routine.

At purchase or refit, the security audit is now a standard line item. A buyer's surveyor will check CCTV coverage and resolution, access-control logs, cybersecurity posture, ISPS documentation for charter yachts and the integration of the bridge alarm and security panels. On charter, ISPS non-compliance can mean refused port entry; on private yachts, weak cyber hygiene can mean an unrecoverable data incident.

Key facts

• Yacht security systems span four domains: physical access, surveillance, perimeter protection and cybersecurity, integrated rather than bolted on.
• Thermal cameras detect approaching craft at ranges reported up to several kilometres, well beyond visible-light CCTV at night.
• Long Range Acoustic Devices (LRAD) project warnings and pain-inducing sound out to roughly three kilometres.
• Charter yachts at or above 500 GT trading internationally require an ISPS Code Ship Security Plan, Ship Security Officer and ISSC under SOLAS Chapter XI-2.
• Private (non-commercial) yachts sit outside mandatory ISPS scope but typically adopt comparable procedures voluntarily.
• Network segmentation isolates bridge/OT, owner, guest and crew Wi-Fi; a separate guest network is standard on modern builds.
• Leading integrators include Videoworks, Van Berge Henegouwen (VBH) and ONE XP.
• Indicative hardware costs: £8,000-£20,000 for a high-resolution thermal camera and £14,000-£27,000 for an LRAD unit.
