Most boats don't sink at sea. They sink at the dock.
A stuck float switch. A dying battery. A bilge pump that quietly gave up three weeks ago. The boat you love can be in trouble for days before anyone notices — and by the time the marina calls, it's already expensive.
The Roam Hub watches the things that actually sink boats, and tells you the moment something's wrong — wherever you are.
-
Bilge pump failure
A failed pump and a slow leak is how boats go down on their own lines.
-
Dead batteries
Drains slowly, then your bilge pump has nothing left when it matters most.
-
Shore power lost
Power trips, the fridge thaws, the batteries stop charging — for days.
-
Dragging anchor
A shifted anchor overnight can put your boat on the rocks by morning.
One device. Everything that matters.
The Roam Hub monitors your boat's vitals out of the box — battery, location, temperature and motion. Start there, and add sensors only as you need them.

Catch a slow drain before it strands you — or kills your bilge pump.

Why owners choose Roam
Roam: Built-in cellular reports from any slip, mooring, or anchorage — no marina WiFi, no SIM to buy.

Locked-in annual contracts and surprise reconnect fees are the norm.

Pro install or hours of wiring before you see a single reading.
Roam: One hub, add wired and wireless sensors over time. Buy only what you need.
Fixed bundles you pay for whether you use them or not.
Roam: US-based people who actually know boats — not a chatbot loop.
Email tickets and a 48-hour wait while your boat sits.

Questions, answered
Do I need marina WiFi or a SIM card?
Neither. The Roam Hub has cellular built in and connects on its own — at the dock, on a mooring, or at anchor. If your dock has WiFi it'll use that automatically to save data, but it's never required.
The Roam Hub is on pre-order — when will it ship?
We're taking pre-orders for the next production run of the Roam Hub. Orders are expected to ship July 27; we'll email you with tracking when yours goes out. Sensors, cables and accessories are in stock and ship today.
When am I charged, and can I cancel?
Your pre-order is placed today to reserve your spot in the run. You can cancel any time before it ships for a full refund — just email us. Once it ships, our standard 90-day return applies.
Can I still buy sensors and accessories now?
Yes. Wired and wireless sensors, cables, and add-ons are in stock and ship right away — including parts compatible with your current Roam. Only the Roam Hub itself is on pre-order.
Is it hard to install?
No. Most owners are done in 15–30 minutes: connect to your 12V battery, add any cable sensors to the screw terminals, and pair in the app. No professional install required.
How does the subscription work?
Plans are simple. If your boat stays in WiFi range you can run free. For monitoring anywhere, cellular starts at just $5/mo billed annually (or month-to-month for a bit more). Pick annual or monthly and change it any time in the app.
What if I lose cell or internet?
The Roam Hub keeps logging on board and catches you up as soon as it reconnects, so you don't lose history in a dead zone. Critical alerts send the moment connectivity returns.
Will it work on my boat?
If you have a 12V system, yes — sail or power. The hub covers the essentials; add wired or wireless sensors for the rest. The build-your-system tool helps you spec it.
What's in the box?
The Roam Hub, mounting hardware, and the wiring harness. Sensors are sold separately or as a kit so you only pay for what your boat needs. You pick your plan in the Roam app once it's installed.
