Navmoor is adept in providing turnkey IALA Compliant solutions to our wonderful maritime industry, be it Navigation, Data or Mooring buoys. We hold stock of IALA Compliant buoys, from 400mm diameter through to 3000mm capable of focal planes of 277mm right up to a whopping 7800mm! Get in touch, let’s see if we can help you.

Data Buoys, when a standard buoy doesn’t quite cut it, and you want your data at your fingertips, we integrate systems and sensors from the very best manufacturers, and couple them with our own intuitive online, web-based, monitoring portal. Here’s just a snapshot of the parameters we can help you monitor:

  • Wave Height, Frequency & Direction
  • Air Temp
  • Humidity
  • Dew Point
  • Pressure
  • PH
  • Wind Speed, Gusts & Direction
  • Dissolved Oxygen
  • Turbidity
  • Water Temp
  • Suspended Solids
  • Salinity

If you need parameters measured outside of the above then do get in touch, with a little integration we can monitor anything you desire due to having full ownership and control of our very own web-based monitoring portal.



We now stock 16-38mm mooring chain in 27.5, 55metre lengths as standard, with mad to measure lengths on very short lead times. We hold a range of sinkers, varying from clump chain, 250kg Cast Iron and concrete, and 1,000kg to 10,000kg Admiralty Pattern Cast Iron sinkers.
Not only do we pride ourselves on the equipment we provide, but our knowledge of moorings spans almost every application, so if you’re unsure or require some assistance with your mooring design, then get in touch, we’ll be happy to help.

Buoy Advice &

Navmoor Advice: when considering a new buoy, be sure to identify the correct IALA designation; Port, Starboard, Cardinal Mark etc. We can help you with this if you are unsure, by providing IALA compliant recommendations. Also consider the depth you intend to moor the buoy and what vessel you intend to install and maintain it. This often determines the total mass of the buoy, its moorings and weight of sinker which can be used. Alongside the above, you must of course consider the users of the buoy, leisure, commercial or both, and what average heights their bridge might be, from there on you’ll be able to determine what buoy suits your application and infrastructure best, as with everything Aids to Navigation, if you’re unsure please do get in touch, we’re here for you!

AIS can be especially useful in reduced visibility conditions such as fog, inclement weather, or large swells. In some instances, we can setup a virtual network of AIS targets from a single station; one buoy deployed with AIS hardware, displaying AIS on the whole channel, virtually and synthetically, as required.

Buoy Lanterns: what lantern you use is paramount to the success of any navigational aid, and when it comes to floating aids, vertical divergence is critical. We would not use anything less than 7° vertical divergence on a stable buoy platform, and for more harsh seas or smaller buoys we would be looking to increase that to 10° or more.

With the latest technology offering significantly lower power consumption, we are now able to offer monitoring and control of even the smallest lanterns, meaning you are informed of their condition and functionality, including its flash character and battery without having to mount the AtoN structure or buoy to check. This method of monitoring is saving Ports & Harbour thousands of pounds in unjustified vessel visits and repeat attendance for repairs. Not only do you know if the battery is running low via an alarming system to your phones via text or email address you can also monitor the locations of the lights & buoys using smart geofencing to trigger alarms should your buoys break their moorings.


Navmoor introduced its online monitoring portal to the world in early 2019, since then it has grown to become the market leading platform, and the only platform which enables you to monitor ANY parameter of ANY deployed asset, regardless of manufacture or age.

We can add monitoring to almost any device, not only aids to navigation. It might be that you have several lights, vibration sensors, meteorological sensors or of course buoys that you would like to monitor, or it might be that you want different data from different assets. i.e. the position, wave height and battery voltage might be important from a navigation buoy, but knowing whether your Port Entry Light is on and at what intensity/range might be what you want to know from another station.

The applications are endless, and as Navmoor is primarily an Aids to Navigation we haven’t even thought outside of our little bubble…. So, what do you want to monitor? No matter what you add to our open-source system, your assets and their data will all appear in our web-based online portal, accessible over any internet browser or mobile device, and the best part of Navmoor’s portal is that you can use whichever medium best suits the location, coverage, and data usage:

  • IoT (internet of Things)
  • GSM or Satcom
  • Radio – LoRa (Long Range)

We can even provide the data directly to Pilots via PPUs, or to VTS over AIS or a direct API (Application Programming Interface). And if the above hasn’t already blown your mind, what if we told you that we can add control options to your portal too…. I know right….. Mind Blown!!!!!!
