4 Great reasons to buy form us:


Don’t continue slipping and having to take your boat out of the water for antifouling costing you $3000/ $4000/ $5000+ each 12/24 months. When a one time capital investment in Barnaclerid, your vessel will be protected from barnacles/hard shell growth for many seasons.

With a Barnaclerid investment your $$ return on average is less than 12 months.

Barnaclerid also saves you money on fuel and engine maintenance. A boat hull that is free of barnacles means it is easier for your boat to maintain normal cruise speed and (WOT) speed. Resulting in less stress on your engine while using less fuel.


Boat Battery Powered Barnaclerid System

Barnaclerid only requires one person less than two minutes to lift and stow the electrodes, ready to sail or cruise away. On return simply spend another two minutes lowering the electrodes back into the water to protect and keep barnacles off your boat. The controller recognizes when the electrodes are in or out of the water and automatically switches off and back on again, saving any input from you. The major advantage of this system is that you always have your barnacle protection with you. As we know, there are places where barnacle can grow to a thickness of 1/3″, or about 8mm, in just a few days and if you spend a few days in a place like that it is a major advantage to have Barnaclerid onboard.

Marina Or Shore Powered Barnaclerid System

Barnaclerid is installed on fixed positions around the boats dock /wharf with the computer controller mounted on your marina connected to shore mains power. You board your vessel and sail away. When you return just secure your vessel and leave knowing on your return your boat will be free of barnacles.

Hybrid Powered Barnaclerid System

This system comes with dual power connection setup, boat and mains shore power. It works as the boat powered systems but in the marina, it can be connected to the mains shore power. While away it is powered from the boat electrical system so the barnacle protection is always accessible.

All this whilst using very little battery power or shore power. It’s that simple, protected from barnacles/hard shell growth!!

The best way to prevent barnacles on your boat is Barnaclerid.

Now your boat is protected from barnacles /hard shell growth again and will be ready whenever you return to cruise away without hassles.


Using Copper Ions, a protective field is established around your hull and running gear which combats barnacle growth, by creating an environment barnacles do not like therefore will not attach to your hull or running gear.

Two, four or more electrodes (dependent on the vessels size) are lowered into the water when your boat is stationary, moored or in your marina berth. A protective field is created between the electrodes by our computer controller, the field is wide enough to encompass your entire submerged hull.

BarnacleRid Operational Concept

WHY Barnaclerid?

Copper has been used by mariners for over 250 years to prevent barnacles from attaching to their boats. As seen in the picture below, the famous Cutty Sark sailing ship, built in 1869. The hull was copper sheathed to prevent barnacles/hard shell growth. Barnaclerid takes this concept to a space-age level and makes it more user and environment friendly. Barnaclerid uses copper electrodes lowered into the water around the boat coupled to our advanced easy to use computer controller creating a copper Ion field to prevent barnacle growth.

Our sophisticated and proven system enhances the effects of copper's protective properties, by submerging between 2-4 electrodes, or more dependent of the vessels size and configuration, just below the water line of your boat usually in line with the centreline of the props creating an invisible, safe, green-friendly non-toxic non-leaching copper Ion field around the hull and running gear. Our sophisticated electronic computer controller with variable controls via touch buttons that are configurable to suit any climate uses low power consumption e.g. 12 volt (500 milliamps to maximum 1.2 Amp hours, depending on climate setting). It works with 12V or 24V boat power systems and all mains shore power of 110V-240V.

Important: We found during the development and testing phase, more than a decade ago, before you install the Barnacle Rid System on your vessel you should start with a totally barnacle free, recently anti foul treated hull. Note! Barnaclerid works in harmony with your anti foul treatment Including prop speed and similar coatings, we have many clients through using Barnacle Rid have extended the time needed to re antifoul for over 5 years and counting, saving thousands of dollars.

Barnaclerid should be Installed the day your boat goes back into the water.

Barnaclerid does not kill barnacles/hard shell growth already attached; it keeps them at bay and prevents them from attaching to your hull by creating a barnacle unfriendly environment. If any barnacles are already attached, however small they will keep growing!

Barnacles attached to your boat do not just cost money$$ with the boat lifting and anti-fouling, they also increase fuel consumption by, on many vessels, up to 40% and cause more engine wear due to more work the engine must do to maintain normal cruise speed due to the extra drag the barnacles cause.

1 review for Barnacle Rid – Electronic Antifoul System – Catamaran – Hybrid Powered

  1. Graham G

    I had a 35 foot cruiser that I had moored in a marina at Bayview in Sydney for a bit over 2 years and due to the water temp and limited water movement I found that I was continually having to dive to scrub the hull as the growth became quicker and quicker after each scrub. I then moved up to a 45 foot cruiser in the same location and not wanting to be continually under the boat scrubbing, I began the search for a solution. I discovered Barnaclerid and bought the 4 electrode model (as per your recommendation) which has now been on the boat for approx. 2 and a half years. I was sceptical at first as I initially purchased the system 3 months after an antifoul and, not wanting to slip the boat again so soon, I put the system on (contrary to instructions) and expected it to work. I ended up with growth starting after a couple of months so I bit the bullet and slipped the boat and antifouled. Clearly following the instructions works as during my subsequent 3 monthly dives under the boat there is only some slime with a small amount of weed on the waterline. There has been minor growth on boarding platform supports which is easily scraped off and a very small amount on rudder and prop. No barnacles anywhere. I have no doubt that I have saved substantially on fuel and general running costs. In terms of the product living up to what it says it will do – it certainly does. In addition, Shane’s service and advice has been exceptional. From my experience I thoroughly recommend the Barnaclerid system – but you must follow the instructions.
