Exterior Designer/Naval Architect: Michael Bagdonas – Design; Incat Crowther – Naval Architect

Sentinel represents a new benchmark in privacy, operational independence, and readiness, conceived as a next-generation superyacht support vessel for evolving ultra-high-net-worth ownership. Developed on the proven 70-metre catamaran platform by Shadowcat, it delivers stability, efficiency, and extended range while elevating the role of the modern shadow vessel into a strategic extension of the primary yacht.

The vessel integrates dual helicopter landing pads, a fully enclosed aviation hangar, and expansive mission decks capable of accommodating advanced tenders, armoured vehicles, drone operations, and specialised equipment. Dedicated accommodation for security and support personnel ensures discretion without compromising comfort or architectural clarity. Collaboration with Allmode provided a refined design framework, balancing complex technical requirements with a composed and cohesive aesthetic.

Sentinel is positioned not as a reactive asset but as a proactive platform enabling autonomy, resilience, and operational control across global cruising programmes. By separating infrastructure from the mothership, it preserves the design purity of the primary yacht while expanding experiential capability and preparedness.

Every aspect of the project was shaped by mission-led thinking from inception. Form followed function, with each structural decision grounded in operational necessity rather than spectacle. The catamaran configuration supports aviation, logistics, and mobility seamlessly, maintaining composure and architectural balance throughout.

Fully bespoke and delivered through Shadowcat’s streamlined concept-to-contract pathway, Sentinel embodies discretion, preparedness, and purposeful design, offering owners uncompromised freedom and confidence at sea.

Its development reflects a collaborative vision focused on adaptability, long-term relevance, and operational excellence, ensuring the vessel remains responsive to emerging technologies, shifting security needs, and increasingly complex global itineraries faced by discerning owners and their professional support teams across global operations and maritime contexts.
