Basic operational concept of barnacleRID
It creates an environmentally friendly, invisible Copper Ion field around your boat’s hull and running gear.
Since Barnacle Rid is environmentally friendly, it will not kill barnacles or other marine organisms but creates an environment that the barnacle larvae do not like, hence they move and settle elsewhere keeping your hull and running gear free of barnacles.

  1. Matthew Chang

    I wanted to send a word of praise for your Barnaclerid products. Prior to purchasing the 3 electrode unit, I was highly sceptical off their effectiveness to control the dreaded barnacle growth on the hull of my boat. After purchasing the unit and re antifouling my boat, I was amazed at the reduction in growth. No hard barnacles even after over a year in the water whilst using Barnaclerid. My fuel burn is down, maintenance is down and we could not be happier. At our last annual maintenance and repaint. It was simply a matter of washing down the hull, no scraping required. In fact I am so impressed I would happily recommend the use of Barnaclerid to any boater who moors their boat. Again congratulations on the product and thank you for all your ongoing assistance.

    We have had your Barnacle Rid System installed on our boat for the past eighteen months. My boat is 24 years old and has leg drives. Prior to having the Barnacle Rid System installed the hull and legs would be subject to numerous barnacles after only a short period of time after anti-fouling. We primarily wanted to stop the barnacles from entering our water intakes and over heating our engines which we have recently replaced with new ones. I work away from Perth for extended periods of time and I’m not home regularly enough to clean the hull and legs. My Dad heard of your system, so we thought we would give it a try. After getting the correct settings with prompt return phone calls from yourself and your agent in Perth we are very pleased with the results we have been getting. We have just had the boat out of the water for annual servicing of the legs and were very pleased to find no barnacles on the hull at all and none in the water intakes of the legs. Not only does your system reduce the number of times I need to get in the water to rub down the hull and legs but it reduces the time I need to spend in the water because I don’t need to scrap away barnacles. The boats on either side of our pen are also seem to be developing less barnacles as well. We have had many fellow boaties at the marina asking what the probes are hanging off the bow and stern of our boat, to which we are more than happy to explain what it is and show them the good results that we are having with Barnacle Rid.

    Just had the bottom wiped down only one barnacle found on the whole boat after over 15 months on our swing mooring . We have not used the boat as of late therefore some weed had grown but easily wiped off. So Barnaclerid certainly keeps barnacles off from my 48 foot catamaran.

  4. Grant Shorland

    My boat which is a 65 foot steel passage maker (photographed below) has been moored in Cullen Bay Darwin for the past 14 Months, and it has been 18 Months since the boat was out of the water back in Bundaberg after already using Barnaclerid for 12 months we found no barnacles, she was out of water for general servicing and we had her re anti fouled whilst out for our trip. We then cruised the East coast Australia to the Kimberly’s in Western Australia and then back to Darwin using Barnaclerid at anchorage. During the last 14 Months in Darwin ‘Northern Territory Australia’ the water temperature ranged between 25degrees c, to a high of 33 degrees C, and the Barnaclerid electrodes have been in the water during this time. I had a dive under the boat a few weeks ago, and found the hull completely clear of barnacles, and also the propellers and stern gear without any sign of barnacles which was very impressive. The hull had some slime around the waterline, but this comes off very quickly once the vessel gets under way at 8 knots it is all gone within a few minutes. I would also like to thank you for all your back up service and free advice since I have purchased the Barnaclerid system from your company it has been terrific over the past 2 years or so. I believe your product is a great invention, and it will allow me to haul the boat out of the water every two years or even longer, which is a great saving when you have a boat which displaces 80 tons.

    Just thought I’d take a moment to thank you for selling a product that actually does what it is supposed to. My 42’ Cruisers Esprit has been in the very warm waters of South Florida since September of last year when I took it out of Dry Dock.. Along with a lot of TLC at the dry dock, it also got a brand new bottom paint in anticipation of using your product. I’ve had your system on it since then till now, a full 6 months. Have a look at the photos for yourself…pretty impressive Sir.
