YachtBrain does NOT charge a monthly fee to connect to your boat.

You have a mobile plan, access to wifi networks, VSAT etc why should we send another monthly invoice for a propriety connection that may NOT work where your boat is or where it moves.

What happens when you go offshore beyond the range of network towers? YachtBrain simply connects to your boat's local network. If you don't have a network on your boat no problem. We can assist getting the right network device from your mobile provider or one of the many inexpensive, readily available devices. YachtBrain uses WiFi to connect to users via UIs and uses IoT standard protocols to connect to devices ensuring it's always connected.

Listen to What YachtBrain Customers Are Saying.

Boat owners love YachtBrain because YachtBrain knows what’s important to boat owners.

Exactly the kind of peace of mind we were seeking. While on a trip to Europe we left our boat at a yard for service. YachtBrain recorded when workers were onboard, and alerted me multiple times when the shore power was inadvertently disconnected. We cannot imagine our boat without YachtBrain.


YachtBrain, you guys hit the nail on the head! Many reasons I chose YachtBrain, but to touch on a few: Easy to install - Easy to connect to phone/computer - Monitoring begins as soon as you power up the Hub - YachtBrain connects to our existing mobile hotspot and VSAT - Remote Control of boat lights, this function is cool, and we use it a lot.


I’m very happy that I chose YachtBrain. Our air conditioner had stopped working so I ran the system overnight with a hose. In the middle of the night, the connection began to leak. YachtBrain began sending alerts that the bilges had kicked on. YachtBrain saved the weekend and our boat.
