From theft to innovation: SeaSight—secure your adventure on the water. The story behind SeaSight. In July 2024, Tony Cantrill returned home from a work trip to discover that his brand-new Ribeye A683 – after just 23 days on the water – had vanished from its swing mooring in St Mawes. The theft, carried out under cover of darkness on a still, high-tide night, left no trace and no immediate explanation.
Initial reactions ranged from disbelief to confusion. With no signs of drift or relocation, the search escalated quickly. Local harbour authorities, the marine police, and even Interpol became involved. The boating community rallied in support, but despite coordinated efforts, the vessel was never recovered.
This incident highlighted a significant gap in marine security – not just in terms of available technology, but in awareness. Leisure boat owners often believe theft is unlikely, and most security systems on the market are adapted from automotive or fleet-based solutions, ill-suited to the dynamics of marine environments.
Drawing on decades of experience in IT and systems engineering, Mr Cantrill began developing a solution tailored to boats. Within a year, this work led to the creation of SeaSight – a suite of practical, purpose-built tools designed to prevent theft, detect tampering, and maintain location awareness even in the event of interference.
SeaSight launched in 2025 with three core products: Secure (a marine-grade lock and cable), Shield (a connected onboard tracking and alarm unit), and Stealth (a concealed, self-powered device for covert location updates). Together, they offer layered protection for small and mid-sized leisure vessels, helping owners safeguard their time on the water with greater confidence.
