Each of the remote modules only requires a mains connection for power. The AIU will require a Reserve power supply, VDR cable and Autopilot cable (if required).

The RF Modules Interference Immunity technology is a proprietary hardware and software feature set that allows wireless systems to be immune to most RF interferers (cell phones, pagers, other wireless systems, etc.).

The WATCHKEEPER+ is the world’s first type approved wireless BNWAS. Not only is the system cost efficient on installation it is more aesthetically pleasing for the super yacht market giving easy integration to existing modules


In the case of the BNWAS you need to give careful thought to the level of initial integration you carry out on the bridge of the vessel, or you might find yourself calling your installers back in, or create a lot of additional work for your crew.

Over the last few months I have travelled all over Europe doing demos of the wireless BNWAS WatchKeeper+. When it comes to compliance technology the general mandate is minimum cost, maximum functionality and an installation that causes least disruption possible. The wireless system ticks all of these boxes.

In every presentation I give I make it clear that if you choose a basic install of any BNWAS you will save a costs but your crew will need to manually control the system. This will result in an authorized member of crew being responsible for activation when underway and deactivation on arrival. It will also require the system to manually reset every 12 minutes.

When the aforementioned circumstances are put the in the context of a busy bridge, you could be creating a rod for your own back. So, you can opt for a variety of automation levels.

• Integrate into the autopilot so the system activates automatically when underway.
• Integrate with ECDIS, a computer mouse, or up to six bridge systems. This will automate the reset process when using bridge systems.
• PIR movement sensors can be installed as the reset function.

As a manufacturer we explain the option but the level of integration and automation is down to the individual yacht policy.

A final thought on BNWAS:

Future-proofing is not often mentioned by many BNWAS companies but it is of vital importance. Current regulations do not require data storage but it is widely believed it will become necessary with two years. We offer a simple SD card based memory storage system that will record up to 500 weeks of data but many systems do not. As regulations are not yet defined consider carefully the system you choose or you might find yourself taking it out again in a couple of years.

As wireless technology offers greater and greater cost saving options on retrofitting we will see more and more wireless technology replace cabling and creating cost saving for refits and new build across the market. We can offer a wired system but the sales ratio is 50 to 1 against the wireless system and shows a clear change in perception and a wide acceptance and trust of wireless technology.

Since the legislation tier that came into force on July the 1st 2012, the Net logic team have been expanding their distribution network by selecting companies with an excellent reputation and wide reach, to offer the wireless BNWAS to their clients as an official distributor.
Distribution partners in the Superyacht sector have generally come to us due to consumer demand. In the case of e3 for example they had already started to receive request for quotes on a wireless BNWAS.
They contacted us and we carried out a demo for the team, this was received with great enthusiasm. e3 decided to stock the WatchKeeper+ as the only BNWAS e3 would supply.
Erik Nieuwmeijer, Group Sales Director for e3 commented:

We are delighted to add the wireless BNWAS  system to our portfolio and to be able to offer it to our clients. We are well aware of the new regulations and are ideally placed to supply and install.

Since that time we have worked together to install many system on some of the Worlds most renowned superyachts. We are now working together to explore core options for the use of wireless technology as a cost saving tool for retrofitting.
