"Keeping watch on surveillance and technology" - how advances in technology have improved superyacht security systems

As the saying goes 'forewarned is forearmed’. Awareness of one’s own surroundings is arguably the most important part of any security system on land or afloat. 

Yacht security systems were traditionally focused onboard in the form of CCTV, pressure pads, access control and maintaining a good lookout. As a result, the first line of defence was essentially the hull, with potential threats only being detected once they were already onboard.

Advances in sensors, tracking devices and navigation equipment resulted in them being used for security purposes. However lack of integration between these standalone technologies meant these systems were limited in evaluating real threats and prone to false alarms. Furthermore, crew were required to analyse data from multiple sources which was time consuming and risked delays in making critical decisions.

Thankfully technology is catching up. Modern security systems provide more intuitive and intelligent solutions to help busy crew and security conscious owners.


Awareness of a yacht's own tenders, toys and guests, as well as the proximity of unknown objects are key aspects of yacht security. An effective security system will depend on different factors such as yacht size and location, but most importantly the profile and requirements of the owner.

That said, common themes do occur when discussing yacht security. Crew are likely to be busy so systems must be easy to use with operators only alerted to an immediate threat to safety, security or privacy. As such, systems must be intelligent, seamlessly linking together different sensor data, analysing this combined information and presenting a clear security picture.

Objects around a yacht fit into three distinct categories: air, surface and underwater. These can also be classified as ‘known’ and ‘unknown’, or distinguished as 'Blue' and 'Red' forces in military terminology.

Known air, surface and underwater assets can include: helicopters, drones, tenders, personal watercraft, seabobs, divers and submarines. However, as unknown objects, these could also pose a potential threat.

The development of trackers for tenders, toys and even humans has improved the ability of a yacht to monitor and track the location of a its own assets, crew and guests. Technology has enabled advances in the way that unknown objects can be detected, tracked, classified and deterred.



Our NiDAR security shield achieves 360 degree situational awareness around a yacht by integrating different hardware and data feeds into a single system - able to automatically detect, classify, track and alert users to multiple air, surface and underwater objects.

Above the water, approaching objects are detected using radar as the primary sensor, linked with long-range cameras and other sensors for confirmation. Underwater diver-detection and navigation sonars are used to identify divers or submersibles.

Detection is just one element. The real power of this technology lies in the merging of data, analysis and tracking of objects using advanced software. These algorithms can automatically classify objects based on factors such as size, shape, speed and moving patterns and rank them accordingly.

The intuitive ‘command & control’ interface gives an operator a complete picture of their surroundings, with live tracks and video feeds overlaid on a map or satellite view. Large touch-screen displays can be located on the bridge or security room, while portable tablets provide mobile access for crew. Security teams located ashore can access the system remotely.


Augmented reality has made it possible for layers of relevant information to be presented over a user’s field of view via the latest smart glasses and head mounted displays.

This ‘augmented security’ enables crew to access and control real-time security information whilst mobile, for example when on passarelle watch, in a tender or monitoring guests swimming and using water toys.

Advances in technology mean that yacht security is no longer limited to onboard as comprehensive 360 degree 'offboard' systems deliver increased awareness. When combined with simplified control systems and mobile access, potential threats can be detected earlier and known assets tracked in real time with more accuracy and ease.

In 2017, watertight security on superyachts is now a reality.
