Oversea devices are much more affordable than other systems we see out there. The Oversea Hub, our gateway, is $299 normally — less during promotional sales — whereas others can be $800 or more and our sensors range from $29 to $69.
Every system is different and we encourage you to compare them and their different features. What we know is that the Oversea system will run longer — important for most boaters who aren’t with their boats for extended periods of time — will be easier to install, and offers unique features like long-range monitoring, Hub sharing and indoor/outdoor location on demand.
The reason we are able to offer Oversea for the prices we do is that Skyhawk is a fully vertically integrated company. We do all of our design and development in-house, and we also do all of our own manufacturing in our US factory. Since Skyhawk’s parent company makes electronic components for industry leaders, we enjoy substantially better component pricing than do others who don’t own their own manufacturing facilities but job it out.
Oversea has a 30-day no questions asked return policy so we urge you to try Oversea and see how it compares. We feel comfortable you’ll see the benefits of our year-round monitoring capabilities and ease of installs — and, yes, the lower price.
Oversea is a flexible monitoring system built around a simple requirement: access to a Hub — whether that’s your own, a dock neighbor’s, or one provided by your marina.
Currently, there are nine Oversea devices
- The Oversea Hub
- Battery Sensor
- Bilge Pump Sensor
- Bilge High-Water Sensor
- Entry Sensor
- Shore Power Sensor
- Motion Sensor
- Sound Sensor
- Temperature, Humidity and Water Sensor
Details about each of these products can be found in the Oversea Shop.
The Oversea system also includes a mobile app that lets you monitor all your sensors, receive and forward alerts, track your boat’s location, and manage your subscriptions — all in one place. The app, Hub, and sensors can all be configured to support multiple boats.
Oversea is available for boaters in the United States and Canada. The system uses advanced cellular IoT connectivity from Verizon to transmit alerts from your boat to the Oversea app, your Hub will need at least a minimal Verizon signal to provide real-time data. The Oversea mobile app can be used anywhere in the world with an internet connection. We are actively working to expand Oversea to additional regions.
The Oversea Hub has two main functions — as a gateway and as a location tracker.
As a gateway, the Oversea Hub uses long-range radio frequency signals to monitor any number of sensors which can be as far away as 1,000 feet (so, on multiple boats if you want). When a sensor triggers an alert, the Hub almost instantly receives it and initiates a cellular connection to broadcast that alert to you in the app, by e-mail and/or by SMS. The Hub also checks to make sure that all sensors are working correctly and monitors their battery power. The Hub also collects, from certain sensors, polling data about battery voltage and bilge pump operation which is also relayed to the Oversea app.
The Hub is also a location tracking device. Using an advanced cellular IoT technology known as eDRX, the Hub can be queried at any time as to its location, so you’ll know where your boat is whenever you want or need to. This location finding technology can be used when the boat is outdoors, of course, but also works when your boat is under a carport or in a storage building where a GPS signal can’t get through.
The Hub also tracks your boat’s compass bearing, and monitors it for changes that might indicate boat theft or boat drift.
Oversea sensors are designed for the long haul — expect at least five years of battery life, with many lasting up to ten. The Oversea Hub typically runs for one to three years on a single set of batteries. All Oversea devices use standard off-the-shelf lithium batteries that are easy to find and replace, and the app will alert you when any device is running low — so you’re never caught off guard.
No, the Oversea Hub draws power from its own internal AA batteries. You don’t need to connect the Hub to your battery, and the Hub will never drain your boat battery as other monitoring systems can.
We offer a 30-day no questions asked return policy — if you’re not satisfied with your Oversea purchase you can return it to us within 30 days of when you received it and receive a full refund on your purchase price, unless the units were damaged by inappropriate use.
If any Oversea Hub or sensor stops working, and our support team can’t solve the problem with you, we will replace the unit at no charge, provided again that there was no inappropriate use or damage to the device.
To return a device, send e-mail to info@oversea.boats and request a return merchandise authorization (RMA) number. We’ll provide you with that number and instructions on how to make the return.
We are pleased to offer free shipping for all orders within the United States and Canada. No minimum purchase is required.
We’ve tested Oversea sensors and most of them can connect to a Hub more than a thousand feet away. The Entry Sensor has a lower range, in the hundreds of feet.
For any single boat or set of boats nearby this range should be perfectly fine. Sensor reach can vary based on where you have your Hub located and where the sensors are located, based on how many walls are between the devices and the composition of the walls.
We urge you to test sensor range on your own. All of our products have a 30-day no questions asked return policy, so in the event you find that your sensor reception isn’t meeting your objectives, we’ll gladly refund your purchase within that window.
The Oversea sensors communicate to the Oversea mobile app via a Hub, so they need a Hub to operate. But it doesn’t necessarily have to be your Hub! If one of your dock buddies has a Hub and his boat is close by yours (whether in the water or out) then your sensors can connect to his Hub. Some marinas may also offer Hub sharing. We offer sensor-only subscriptions for Oversea users that use someone else’s Hub
Keep in mind that without your own Hub, you won’t get to utilize its location-on-demand capability or its boat movement detection features. And if your friend with the Hub is on the water, you wouldn’t be able to get sensor alerts.
Skyhawk currently offers eight different sensors to help you oversee your boat’s safety, security and readiness. These sensors are:
- Battery Sensor: Monitors your battery voltage and alerts you if it’s too low or drops too rapidly
- Bilge Pump Sensor: Monitors the operation of your bilge pump and alerts you if its running too frequently or for too long
- Bilge High-Water Sensor: Detects high water levels in the bilge, ensuring early detection of potential flooding issues. This sensor also measures and reports the bilge temperature
- Entry Sensor: Attaches to your doors, hatches, cabinets, lockers and alerts you if someone has opened them
- Shore Power Sensor: Notifies you if your shore power connection is lost for any reason
- PIR Motion Sensor: Alerts you if it detects movement within its “viewing cone” of 100 degrees. Range of 16 ft
- Sound Sensor: Monitors for loud sounds (greater than 80 dB) such as smoke detector or CO2 and alerts you immediately when they sound
- THW Sensor: Alerts you when the bilge level hits the height you set, and also monitors the temperature and humidity around it
Yes, you will need to subscribe your Oversea devices to connect them to the mobile app. Subscriptions are purchased on the Oversea app as part of the setup process for each device.
Oversea subscription costs are determined by the number of devices in your Oversea network and whether you opt for an 1-year or 2-year subscription. All subscriptions are paid in advance for the selected term and will auto-renew unless canceled. You will receive advance notice of any renewal.
A subscription is necessary to connect your Oversea devices to the mobile app. Subscriptions are purchased through the Oversea app as part of the setup process for each device.

Unlike other boat monitoring systems, Oversea is designed to monitor your boat all year round. Since all Oversea devices run on off-the-shelf batteries, for multiple years, you can keep monitoring active for security and safety features whether your boat is in the water, on a trailer, in storage or anywhere else. Theft doesn’t stop in the off-season; the majority of boat thefts occur when the boat is on a trailer.
As such, we don’t provide a seasonal subscription rate since our goal is to protect your boat at all times during the year.
