BRNKL
Your BRNKL unit is the hardware that gets installed on your boat to enable monitoring for:
- Batteries
- Pitch/Heel
- Location
- Temperature
- Humidity
- Bilge Pump
A BRNKL is needed to add any other accessories for security and monitoring.
Protect your catamaran with award-winning security and monitoring technology trusted by government and military fleets. Get peace of mind whether you’re leaving your boat behind for the season or sailing across the ocean. Receive alerts in case of any suspicious activity, such as unexpected movement or unauthorized access, and be made aware of potential maintenance issues before they become costly repairs.
We believe that ensuring security and monitoring for catamarans should be hassle-free. Check out our recommendation below for basic monitoring hardware, security accessories, and upgrades below. Get in touch with us at any time to create a personalized system.

Build Your Kit
Step 1: Start With Basic Monitoring
For catamaran 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 catamaran 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 catamaran owners.
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 BRNKL work if I’m going offshore?
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 the purchase of a BRNKL) to ensure connectivity.
How many DC Relays do I need?
Since your catamaran could have up to six bilge pumps and a minimum of three battery banks, you’ll likely need four DC Relays so that the additional bilge pumps can be connected to the Digital Inputs on the BRNKL.
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.
