Vessel Arrest
Fence
The first British maritime barrier with NPSA approval. A scalable, above-water security fence for ports, harbours, nuclear facilities, and critical waterside assets.
A passive, highly visible deterrent that stops attack vessels before they can cause damage
The Vessel Arrest Fence creates an above-water security zone to protect assets from unauthorised maritime intrusion. Designed to complement onsite force protection for ships, harbours, ports, offshore platforms, nuclear facilities, and waterside assets, it provides a highly visible fence-like barrier that physically stops and captures threatening vessels.
Scalable by both height and diameter, the fence is designed and adjusted to suit various local current and weather conditions. It can be installed at any tidal or non-tidal venue, and operated — towed, opened, and closed — by a small boat or via automated and manual operating options. Manufactured to any length, to customer specification.
Built for permanent protection and rapid deployment
Passive & Highly Visible Deterrent
The above-water fence structure provides a clear, unmistakable security zone boundary. Its visibility alone acts as a powerful deterrent before any interception is required.
Scalable to the Threat
Height from 1.2m to 2.4m, adjustable diameter, and manufactured to any length. The fence is designed and configured to suit local current, weather, and threat conditions.
Swarm & Repetitive Attack Resistance
The Vessel Arrest Fence is engineered to withstand repetitive single craft attacks and simultaneous swarm attacks, maintaining the integrity of the security perimeter throughout.
Flexible Installation
Permanent or temporary configuration. Can be towed, opened, and closed by a small boat, or operated via automated or manual control options. Suitable for tidal and non-tidal environments.
IALA & IMO Compliant
Manufactured in standard IALA sections with mooring buoys at intervals no greater than 100 metres, in full compliance with current maritime zoning legislation.
Custom Specification
Manufactured to customer-required lengths and colours. Yellow as standard, with full bespoke options available to meet site-specific requirements and operational preferences.

PWC Capture Solution
A unique feature of the Vessel Arrest Fence is its ability to not merely stop a personal watercraft — it physically captures and holds the watercraft in place. This distinguishes the fence from all other maritime barriers and provides a decisive tactical advantage in scenarios involving jet skis and personal watercraft.
The system is engineered to withstand both repetitive single craft attacks and simultaneous swarm attacks, maintaining the integrity of the security perimeter throughout. A great system for deterring or stopping small boats and jet skis — the Vessel Arrest Fence is a fully scalable system.
Stop & Capture
Does not just stop — physically captures and holds personal watercraft in place.
Swarm Attack Resistance
Engineered to withstand simultaneous multiple craft attacks without perimeter failure.
Repetitive Impact Tolerance
Maintains structural integrity through repeated single craft impact events.
The first British maritime barrier with NPSA approval
The Vessel Arrest Fence is independently tested and approved by the UK Home Office, Department of Transport, and the National Protective Security Authority — making it the first British maritime barrier to reach NPSA approval following a rigorous competitive trial process.
It is deployed in ports and used for protective maritime security at international and national government meetings, as well as Olympic maritime protection. The fence has demonstrated real-world performance across a wide range of operational environments, from major event security through to permanent critical infrastructure protection.
