Why boat theft isn't rare — and what owners can do
The hidden reality of boat theft in the UK, and why a lack of awareness is allowing it to fly under the radar.
Many boat owners still believe their vessel is safe once moored on the water. Our founder, Tony Cantrill, is living proof that this isn't true.
SeaSight was born after Tony's boat vanished without a trace from its mooring in Cornwall — a theft that involved local police, harbour authorities, Project Kraken, and even Interpol, yet led to no recovery of the vessel.
The hidden reality
Unlike car theft, marine theft often goes under-reported, making it appear far less common than it really is. Incidents of boat theft rarely make national headlines, and patchy national reporting means the data on stolen boats and engines is sparse and insufficient.
This paired with the common myth that "boats don't get stolen off the water" is allowing a real problem to go unchecked.
What you can do
Layered security is the most effective approach — combining physical deterrence, smart monitoring, and discreet tracking. SeaSight was built to empower boat owners with exactly that: the technology to prevent theft before it happens, and the tools to assist recovery if it does.
