DockSafe is the stray voltage detection platform built for the water itself. Continuous monitoring. Mobile diagnostics. AC and DC. Plus a complete documented record of what's been in your basin — the part code-compliant infrastructure was never designed to provide.
A marina with fully code-compliant electrical infrastructure — ELCI on every pedestal, GFCI on every outlet, wiring up to standard — has addressed the shore power circuit. That's necessary. It's not sufficient. The systems built to protect circuits were never designed to measure what accumulates in the water itself.
Between 10 mA — where a swimmer paralyzes — and 30 mA — where the breaker finally trips — sits the band where most chronic marina leakage actually lives. No panel device sees it. And DC sources don't appear on this scale at all.
Voltage gradients in water don't stay contained to one slip — they radiate outward and overlap. Four boats each contributing a "safe" 5–8 mA below their individual trip thresholds can combine into a 26+ mA field in the water column. No single circuit registers anything unusual. The gradient exists entirely in the aggregate — and the only instrument that can measure it is a sensor in the water itself.
"This is not a gap in the rules. It is a fundamental limitation of the technology. Circuit protection was designed to protect circuits. It was never designed to measure what accumulates between boats in open water — and no amount of ELCI compliance closes that gap." — DockSafe ESD Research Brief, 2026
DockSafe is hardware + software that complements every panel-level protection a marina already has. It catches what the circuit can't see, builds a permanent record, and helps operators act on what they find.
Available boat-mounted or handheld. The full-basin coverage and diagnostics tool. Every scan produces timestamped, GPS-logged data that becomes:
Most "monitoring" systems sample intermittently. The DockSafe fixed array doesn't. Sensors are always on, always watching.
DockSafe doesn't just report readings — it interprets them. The AI cross-references every event against contextual signals: time of day, water level, recent precipitation, and dozens of other environmental factors. Marinas see not just what's happening, but when it tends to show up.
Most boat-side electrical faults are intermittent, not constant. A failing charger trips under load. A degrading battery leaks only at night. Snapshot detection misses these. DockSafe flags recurring issues across cycles and surfaces patterns as patterns — not isolated events.
When a hazard is flagged, the work starts. Operators log remediation steps, track vendor visits and repair history, upload invoices, photos, and supporting documents. Cross-case correlation automatically surfaces an area's prior cases — so recurring problems get the recurring attention they require.
A single number that captures the electrical safety state of the entire basin at a glance. Useful for operator dashboards, board reports, insurance reviews, and quarterly safety meetings. Think of it as a credit score for marina electrical safety — updated continuously.
The DockSafe platform lives at app.docksafevoltage.com. Every scan flows into a marina-wide picture — readings, trends, flagged areas, and the documentation operators need on hand.
Kedrick McKenzie founded DockSafe after years of recovery diving across the TVA lake system. Through Need a Diver — a recovery operation working alongside law enforcement and rescue squads across East Tennessee — he's responded to underwater emergencies, including cases involving electrical hazards.
DockSafe didn't start as a theoretical problem. It started in the water.
Built end-to-end from that field experience, the platform combines fixed sensor arrays, mobile diagnostic scanners, and continuous monitoring with the documented record marina operators want as part of how they run their basin. The goal is straightforward: give operators a real picture of what's in their water — and a real record of how they've managed it.
Regulation is advancing. Insurers are aligning. Documented monitoring is becoming a standard part of how thoughtful marinas operate. DockSafe is built for operators who already take this seriously — and want the tools to show it.
The 2023 NEC adds per-boat leakage testing requirements that take effect January 1, 2026 — a meaningful step toward more measurement and more documentation at marinas with four or more shore-power receptacles.
DockSafe doesn't claim NEC compliance — that's the responsibility of your electrical infrastructure. We measure what code-level protection isn't designed to: the water column, DC sources, and combined fields between vessels.
Major marine insurance carriers have published formal ESD prevention guidance. ABYC compliance is increasingly part of marina coverage conversations, and documented monitoring is becoming a recognized signal of operator diligence.
A consistent record of monitoring and follow-through is what insurers and surveyors increasingly want to see — alongside the equipment standards they already check.
The operators most respected in the industry are the ones who can show what they've been doing — what they measured, when they measured it, what they found, and how they responded. That's true today, and it's becoming more true every year.
A continuous monitoring record isn't a fear-driven defense — it's how thoughtful operators run their basin. DockSafe is built to make that record easy to maintain and easy to share.
