NOXX HYD™ was the original “Hydrosonic Hull Tender” developed by Derek Knox of Hull Tender International Inc.

The journey of NOXX HYD™ began in the 1970s when the original developer, Derek, needed to register the 34-foot ketch-rigged sailboat that had just completed construction. While registering the boat, Derek had an insightful conversation with the government official processing the registration. Having been involved with submarines previously, the gentleman told Derek that it had appeared to him that sonar had kept areas of the submarine in the vicinity of the sonar and other transducers clear of marine growth. Consequently, he then went onto introduce Derek to the Barnacle Bill. A very early low-frequency antifouling system with two transducers.

And this was the inspiration of the Hydrosonic Hull Tender. Derek wanted to protect his boat from marine fouling without harming the environment. 

Acquiring Hull Tender International Inc. in 2016, EMCS Industries Ltd has been excited by this technology and its results and its potential as part of our MARELCO™ Sentinel hybrid antifouling solution
