Your Relay Alarm triggered for fourteen minutes at 2am. Did you know?
A relay alarm that trips and keeps tripping in the middle of the night means something needs attention — and you have a shrinking window to do something about it.
Most on-board incidents don't escalate dramatically. They develop slowly. A relay that's cycling when it shouldn't. An alarm that trips again and again. Something is triggering it — and if nobody notices, a manageable situation becomes a significant one.
Relay Alarm Alert
02:14 AM
Black Pearl Relay Alarm triggered for 14 min 22 sec. Bilge Alarms armed. Battery: 12.4V. Shore power: connected.
That alert gives you something most boat owners don't have: time. Time to check the live feed. Time to call the marina. Time to make the difference between a false alarm and a very expensive morning.
The alarm triggering is not the emergency. The alarm triggering and nobody knowing — that's the emergency.
Shore power: the risk hiding in plain sight on your marina berth
Your shore power connection does more than charge your batteries. When it fails — it starts a chain of events most boat owners only discover when it's too late.
The sequence is almost always the same. Shore power disconnects — a loose fitting, a tripped breaker, a marina fault. The battery bank starts running down. The bilge pump keeps drawing. Within 12–24 hours the bank is flat. And if water is getting in anywhere, there's nothing stopping it.
"Shore power loss is almost never the problem. It's what happens in the 18 hours after it that you need to know about."
BoatSecure monitors your shore power continuously. The moment it disconnects, you know — before the battery runs down. Before the pump stops.

Hutchwilco Boat Show. Come and find us at Stand 801.
The Hutchwilco New Zealand Boat Show opens 15 May at Auckland Showgrounds. Stand 801 — live devices, real demos, and a $1,200 competition to enter.
If you've been thinking about BoatSecure, the show is the place to see exactly what it does. Live devices, real telemetry — bilge pump activity, battery voltage, shore power status, GPS location, on-board motion — so you can see what your boat would be sending you right now.
"Enter at boatsecure.net/boatshow. Five prizes, each worth $1,200. Draw 18 May."
Five prizes — device ($750) plus six months monitoring ($450). You don't have to be at the show to enter, but come say hello at Stand 801 if you are.
Your mooring is holding. Until it isn't. Here's how you find out.
A mooring or pile berth moves. That's normal. But there's a difference between a boat swinging on its mooring and a boat that has quietly drifted into the channel.
GPS drift alerts are one of the most underappreciated features on a BoatSecure device. Your boat has a home position. If it moves beyond a defined radius, you get a notification. What triggers it tells you a lot about what might be happening.
Three reasons a moored boat moves
The mooring failed. Shackle let go, swivel corroded, mooring block dragged. The boat is now free — your vessel is now someone else's problem as much as yours.
The lines chafed through. Chafe is slow but relentless. A GPS alert at 6am means you can check before the boat is fully loose.
Someone moved it without telling you. Theft, joyriding, or marina repositioning. You want to know the moment it starts, not the next time you visit.

Optomystic, Putaki Bay, Waiheke Island Vessel has moved 54 nautical miles from registered berth position. Last known heading: 247°. No shore power. On-board motion detected.

BoatSecure doesn't prevent any of these things from happening. What it does is make sure you're not the last person to know.

The question every boat owner asks at 3am. We built the answer.
There's a specific kind of anxiety that comes with owning a boat you can't see. We know it well. BoatSecure exists because that anxiety is worth solving.
You're lying in bed and you remember the forecast called for northerlies. Or you left the shore power connected and now you're wondering if the lead is okay. Or you just haven't been to the marina in ten days and the silence is starting to feel loud.
That feeling is what BoatSecure is built to replace. Not with false reassurance — with actual information. Your bilge pump is quiet. Your batteries are at 13.1 volts. Shore power is connected. Your boat hasn't moved. You can go back to sleep.
"The goal is to make sure that when something actually needs your attention, you find out immediately — not on your next visit."
We designed BoatSecure around five things that matter: bilge activity, battery voltage, shore power status, GPS position, and on-board motion. These are the five things that, if you knew about them in real time, would prevent the overwhelming majority of marina losses.
24 hours of battery data — continuous monitoring, no gaps
The device is compact, professionally installed by a marine electrician, and sends continuous telemetry to your phone. Setup takes under an hour. After that, it just runs — quietly, continuously, whether you're at the marina or halfway around the world.
Peace of Mind Through Intelligent Remote Vessel Monitoring
How LoRaWAN technology and a partnership with DCMarine are changing what it means to leave your boat unattended — and why the right wireless protocol matters on the water.
For most boat owners, the time between visits to the marina is a gap in awareness. You lock up, walk away, and hope nothing changes until you return. BoatSecure was built to close that gap — and the technology behind it matters more than you might think.
The Challenge
Unattended boats face a slow parade of risks: bilge water rising, shore power tripping, batteries draining, moorings slipping, intruders boarding. None of these escalate instantly, but all of them worsen with every hour nobody notices. Traditional monitoring systems rely on Wi-Fi or cellular connections, both of which have serious limitations in a marine environment. Wi-Fi doesn't reach reliably across a marina. Cellular coverage at a mooring can be patchy, and it drains battery fast.
The Solution
BoatSecure uses LoRaWAN — a long-range, low-power wireless protocol designed specifically for IoT sensors that need to send small amounts of data over long distances while running on minimal power. Each BoatSecure device monitors five critical inputs: bilge pump activity, battery voltage, shore power status, GPS location, and door and hatch intrusion. The data travels via LoRaWAN to a gateway, which forwards it to the cloud, and then straight to your phone.

Real-World Benefits
The proof is in the field. BoatSecure partnered with DCMarine, a respected New Zealand marine electronics installer, to deploy and support the system for boat owners across the region. The partnership means every installation is done by a qualified marine professional who understands vessel electrical systems — not a consumer gadget you stick on a wall.
"The first time a customer called me to say their boat was taking on water at 3am and they'd already arranged a diver — that's when I knew this technology changes everything. It's not just monitoring. It's peace of mind you can't put a price on."
— Dylan Cox, DCMarine
Owners report catching bilge issues days before they would have discovered them on a routine visit. Shore power trips are flagged within minutes, not on the next weekend trip. GPS drift alerts have prompted owners to check their moorings and, in several cases, discover chafed lines before they parted.
Why LoRaWAN?
LoRaWAN is uniquely suited to marine monitoring for three reasons. Range: a single gateway can cover an entire marina — hundreds of vessels — from one installation point. Power: sensor batteries last years, not days, because LoRaWAN devices sleep between transmissions and wake only to send small data packets. Penetration: LoRaWAN signals pass through fiberglass, wood, and mild steel hulls — materials that block Wi-Fi and Bluetooth entirely. For a device sitting inside a bilge or behind a battery bank, that penetration is the difference between a reliable signal and no signal at all.
The Result
The combination of LoRaWAN hardware, professional installation through DCMarine, and the BoatSecure monitoring platform gives boat owners something they've never had before: continuous, reliable visibility into what's happening on their vessel, anywhere in the world, without draining batteries or depending on marina Wi-Fi. It's not a gadget. It's infrastructure. And for the owners who use it, the anxiety of the unattended boat is replaced by something far more useful — confidence backed by data.
