Meet the Sentinel: ShadowCat Unveils Next-Generation Support Yacht with Integrated Surveillance Drones
At the 2025 Fort Lauderdale International Boat Show, visionary builder ShadowCat introduced its latest creation — Sentinel — a revolutionary 71-metre catamaran concept that redefines the role of the support yacht. Developed in collaboration with security specialist Allmode, Sentinel is conceived not merely as a vessel, but as a mobile ecosystem of protection, designed to provide total situational awareness and peace of mind at sea.

A Floating Perimeter of Protection
Built upon ShadowCat’s acclaimed twin-hull platform, Sentinel integrates a sophisticated surveillance and response network that blends maritime engineering with cutting-edge defense technology. A fleet of autonomous and piloted drones works in coordination with advanced radar systems, long-range optical tracking, and thermal imaging sensors to deliver 360-degree reconnaissance in real time: establishing what the designers call a “mobile perimeter of protection.”
This intelligence network operates seamlessly, providing live data and aerial coverage without intrusion, ensuring that the owner’s privacy remains as intact as their security.
“At this ownership level, privacy and security are inseparable,” said Jennifer Johnston Smith, ShadowCat’s Commercial Director. “Sentinel allows owners to live without hesitation, travel without constraint, and enjoy life at sea knowing their world is protected in every dimension.”
Secure by Design
Every facet of Sentinel is built around quiet strength. A reinforced citadel serves as a secure refuge for owners, guests, and crew; equipped for multi-hour endurance, independent communications, and full internal control. Critical stairwells and compartments are ballistically shielded, while shielded communication hubs and encrypted data systems ensure operational security under any circumstance.
Drone docking bays are directly synchronized with the mothership’s control infrastructure, creating a fully integrated intelligence ecosystem. The result is a vessel that senses, evaluates, and responds: protecting discreetly, without ever intruding on the guest experience.

Unrivaled Support Capabilities
While Sentinel is a guardian first, it also remains a true multi-role support vessel. Designed to carry submersibles, tenders, sportfishing boats, and even armored SUVs and ATVs, the yacht’s hydraulic launch system enables rapid deployment of all craft. Twin certified helipads permit simultaneous helicopter operations, supporting transfers, logistics, or emergency extraction.
ShadowCat has also prioritized the wellbeing of both guests and crew. Sentinel can host specialist personnel (from security teams and pilots to onboard medical staff) within purpose-built quarters. A fully equipped medical suite, with optional isolation rooms, a recompression chamber, and physician accommodations, offers capabilities equivalent to high-end terrestrial facilities.
The Intelligence of Discretion
More than a support yacht, Sentinel embodies a new philosophy of foresight. Every line, structure, and subsystem is engineered to defend quietly, operate efficiently, and communicate seamlessly, all while maintaining the elegance expected of a vessel in the superyacht class.
“This vessel is about foresight,” added Smith. “Every structural element was conceived to protect quietly — from reinforced bulkheads to the embedded intelligence network that keeps the owner informed and secure without ever disturbing the guest experience.”
The Future of Support Yachts
With Sentinel, ShadowCat extends its legacy as a pioneer in multi-hull support design, blending security, luxury, and innovation into a single purpose-built platform. As superyacht ownership evolves, this concept represents the next frontier, where cutting-edge technology and refined discretion converge to ensure that freedom at sea remains absolute.
