Home / Security


Unfortunately, worrying about the security of your boat is a real concern for most boat owners. Whether in a marina or on a swing mooring, the possibility of a break in or the theft of valuable items kept onboard is something at the back of every boat owner's mind.

Whilst VirCru can’t stop bad things happening, our products can make sure you know about them immediately, can react quickly and be prepared constantly.

No doubt you make every effort to ensure your boat is as secure as possible. From choosing the best location through to participating in the local boat watch, every owner wants to make sure their boat is looked after.

The VirCru Motion Sensor is engineered to detect movement within a specific area, informing you if something or someone unwanted is on your boat. When connected to the VirCru Smart Boat system, any unwanted intrusions will trigger an alert to the VirCru App so you can react immediately.


The VirCru Tag can be used to alert you when a door or hatch is opened on your boat.

Your boat probably isn’t just your boat. It may also be where you keep paddle boards, your tender with an outboard, bikes… all the other things that make being on your boat even more fun. The VirCru Tag can be used to alert you if anything is removed from your boat.


Owning a boat is a huge amount of pleasure, but trying to keep on top of your boat-related administration can also be a huge commitment. To keep the details of everything relating to your boat in one place, we've created an inventory management system available in the VirCru App.

Configure alerts so you are reminded when something requires your attention. Keep a record of life jacket information and service dates, photos of valuables, insurance documents and more.

Frequently asked questions

VirCru is a system of sensors that allows you to monitor and control your boat from anywhere.  These sensors offer boat owners three core functions:  

  • Notifications. VirCru ensures your boat is functioning correctly by constantly measuring bilge levels, battery power, water levels and more. If anything requires your attention, the VirCru app will notify you immediately. 
  • Monitoring. VirCru can alert you via the app if your boat is broken into, or equipment is taken. Geofencing functionality is designed to assure you that your boat remains where you left it, even over long periods. 
  • Control. You can use VirCru to ensure your boat is ready for your arrival. Control cabin temperature, humidity and lighting through your mobile device. You can even get the fridge cold before you set sail.

VirCru offers coverage across the UK, all of mainland Europe and the EU.
If you need coverage outside of Europe, we can remotely update the SIM in your Hub and provide service globally
The key exception being the USA – we're working on this!). Please get in touch with our customer service team if you would like to do this.

VirCru is based around three key components:

  • The VirCru Hub - a GPS mobile connected device that connects with the VirCru App on your phone and wirelessly to the other VirCru devices on your boat. As well as providing the connection between you and your boat's devices, the VirCru Hub uses GPS to enable our GeoFence and Anchor Drag functionality as well as monitoring the angle of your boat (listing) and constantly recording the temperature ambient to the location of the Hub.
  • The VirCru App - the main way that you interact with the VirCru Smart Boat System. It is built around a main dashboard that gives an overview of your sensors, combined with in-depth tools to give you the full picture of your boat and a range of inventory management functions.
  • VirCru Sensors and Tags - the sensors and tags available in our product range allows you to customise your VirCru solution to meet the exact needs of your boat. Each sensor transmits information to the VirCru App, and sensors that monitor similar sections of your boat eg. cabin sensors, bilge pump sensors can be grouped together. VirCru’s sensors communicate with the VirCru App in your phone to deliver updates on your boat in real time. 
  Here’s an example of VirCru in action:  
  1. A boat owner uses the VirCru App and VirCru Door Sensor to configure an alert when a cabin door is opened. 
  2. While the owner is away from their boat, an intruder enters the cabin. Consequently, the Door Sensor located on the cabin door detects this movement. 
  3. The VirCru Door Sensor communicates with the VirCru App, informing the App that the door has been opened. The VirCru App immediately sends a notification to the owner, who takes the appropriate action to resolve the issue.
