How It Works 

Barnacle Rid saves fuel and maintains hull speed

Don’t continue to let slipping and taking your boat out of the water and antifouling cost you $3000/ $4000/ $5000+ ($AUD) each 12/ 24 months. When a onetime capital investment on Barnaclerid, averaging $2000 ($AUD) will be protected from barnacles/ hard shell growth for many seasons.

With a Barnaclerid investment your $$ return 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. Resulting in less stress on your engine while using less fuel.

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 returning the electrodes to the water to keep barnacles off a 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.

All this whilst using very little battery power. You also have the option to run from shore mains power.

It’s that simple, protected from barnacles/ hard shell growth!!

The best way to prevent barnacles on boats is Barnaclerid. Simply lower the electrodes into the water when you’re finished with the boat and raise them when you return. There is no need for killing barnacles when you have electrolytic anti-fouling system from Barnaclerid.  


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

Electronic barnacle prevention

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.

Important: Before you install the Barnacle Rid System on your vessel you should start with a totally barnacle free, recently anti foul treated hull.

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

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.

See video to see how simple the electrodes are stored prior to sailing away.

Barnaclerid does not cause electrolysis or galvanic corrosion. It has been independently tested, and we’ll happily provide you this report on request.

Why Barnaclerid? 

Copper has been used by mariners for centuries 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. Barnacle Rid takes this concept and makes it more user friendly. Barancale Rid uses copper ions lowered into the water around the boat and an easy to use computer controller 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 vessels size and configuration) just below the water line of your boat 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). 12 volt / 24 volt and all mains shore power/inverter voltages available, 240 volt, 110 volt etc.


The Computer controller is covered to the original purchaser from any design or manufacturing faults.

Barnaclerid is protected by one or more USA and/or foreign patents or patents pending.  We value creativity and will pursue all legal avenues at our disposal to protect Barnaclerid’s design worldwide.
