A superyacht is one of the few environments that is simultaneously a home, a workplace, and a moving target. It carries significant value, a rotating cast of guests and crew, and a route that is often published months in advance. Security at sea is its own discipline — and it rewards owners who plan ahead.
Drawing on seasons spent protecting vessels across the Mediterranean and beyond, here is what matters most.
The risks are not what most owners expect
Piracy makes headlines, but for most private voyages the real exposure is closer to shore:
- Port-side vulnerability. A berthed yacht is accessible, observable, and predictable — the highest-risk state in most itineraries.
- Insider and access risk. Large crews, contractors, and guest entourages mean many people hold keys, codes, and schedules.
- Information leakage. AIS tracking, social posts, and marina chatter make a vessel's location trivially easy to find.
- Tender and waterline approaches. Small craft and the swim platform are the easiest unmonitored points of entry.
Pre-voyage risk assessment
Security begins long before the lines are slipped. A thorough assessment covers the cruising itinerary, each planned port, regional conditions, and the vessel's own vulnerabilities:
- Route review with primary and alternate ports, and no-go areas flagged.
- Port-by-port intelligence: local crime, reliable agents, medical and extraction options.
- A physical survey of the vessel — access points, lighting, camera coverage, and a designated secure space.
Onboard security
At sea, a small, maritime-trained detail integrates with the crew rather than displacing it. Core measures include:
- Access control at the passerelle, tenders, and swim platform — the points that are routinely left open.
- Anti-boarding readiness and clear, rehearsed procedures for an attempted approach.
- A muster and safe-room plan every guest and crew member understands without being alarmed by it.
- Watch routines that tighten at anchor and overnight, when vessels are most exposed.
In port and ashore
Most incidents happen at the interface between ship and shore. Coordinate berth security with the marina, manage who can approach the vessel, and extend protection to guests heading ashore — including helicopter and tender transfers. This is where maritime and close protection overlap.
Key takeaways
- The berth, not the open ocean, is usually the highest-risk state.
- Assess the route, every port, and the vessel itself before departure.
- Control the tenders, passerelle, and swim platform — the quiet entry points.
- Limit AIS and social exposure that broadcasts your location.
Every vessel and itinerary is different. Our Maritime & Superyacht Security teams handle everything from the pre-voyage assessment to onboard details and port coordination — anywhere in the world.
