Build Your Kit
Step 1: Start With Basic Monitoring
For boat owners who are looking for a simple monitoring solution, we highly recommend our basic monitoring kit. With a BRNKL and a shore power sensor, you’ll be able to keep tabs on your boat while you’re away and monitor critical systems around the clock.
Step 2: Add Security Accessories
To go beyond basic monitoring and protect your boat from unwanted visitors and theft, add security accessories to your BRNKL to create a custom security system. For example, add a door sensor to detect unusual activity, a camera to keep eyes on your boat, or a siren to scare off intruders.
Note: Any wireless accessories require a BRNKL Mate connected to a BRNKL.
Step 3: Add The Extras
Round out your security and monitoring system with the accessories frequently bought by cuisers.
I purchased a BRNKL security system for our new boat and I am very happy with it. A few years ago we have two motors stolen and I did not want anything like that to happen again.There have been a couple of things that came up after installation and the support is fantastic by phone and email. I highly recommend this product and company.
My boat is moored fulltime and I was looking for security as well as piece of mind. Having been a boater my entire life, I knew the features I wanted and found everything I needed in the Barnacle System.The app is easy to use and gives me a complete profile of my boat in seconds. From the times I just want to check in to the stormy nights when you want to know your boat is secure, this is the answer.Brandon and Sean were excellent to deal with and may be the most accommodating business owners that I have had the pleasure of working with. They exceeded all of my expectations. Great communication, personal service and an impecable install.If you value your investment in your boat, then this is a must have.
We have been working with Brandon and the team at Barnacle Systems since they launched and only have great things to say about their products, their professionalism and the company in general. We have acted as a distributor of the BRNKL product and are now a technology partner with Barnacle. They are doing great things in the vessel monitoring and security arena and I have no issue in recommending their products to anyone who asks.
One of the best investments I have made in years. I love my BRNKL system. I installed it and the Mate system on my 26' boat and now have complete confidence on its security from the comfort of my home. I am constantly monitoring the batteries, bilge and humidity from my phone.Sean and the crew at BRNKL are always available to answer questions and quick to respond although the app is very intuitive and easy to use. I will never hesitate to suggest to my boating/fishing friends about the product and the crew at BRNKL
We love our BRNKL! It has alerted us to shore power disconnect which has prevented battery issues. It has also been great to know our battery status at all times. Especially at anchor and while we are ashore we can tell if our methanol fuel cell has turned on to keep the batteries charged. We also like the geofence to track if the anchor is dragging, the ability to monitor the barometric pressure and the boat’s environmental temperature and humidity. Also BRNKL has awesome customer service!

Frequently Asked Questions
Will it work if I’m going offshore?
The BRNKL communicates over a cellular connection, with a global SIM card built right into it. If you’re headed offshore or somewhere remote with little to no cell service, use an external satellite (included with purchase of a BRNKL) to ensure connectivity.
How many DC Relays do I need?
It’s common to see cruisers requiring two DC Relays where the dedicated bilge input of the BRNKL is connected to the aft bilge, then the DC Relays connect the forward and mid-ship bilge pumps to the BRNKL digital inputs.
What security accessories do I need?
If you’re looking for a basic security system, we recommend three wireless door sensors (main entry, port entry, and starboard entry) along with a second camera in order to have a view in the pilot house and a view in the saloon. Note that wireless sensors and a second camera require a BRNKL Mate connected to your BRNKL.
If you don’t want to have a siren on board, you can stick with door sensors to know if someone has broken in instead of having a possibly intrusive audible siren.
Can I purchase a pre-packaged BRNKL and accessory bundle?
Yes! We offer three standard BRNKL kits, with accessories aimed to meet your unique needs. To view and purchase the Monitoring Kit, Security and Monitoring Kit, or Premium Kit, head to our shop page.
