Research and Development

Our research and development programme is ongoing and we will bring new products to the market place as they are developed. We are committed to providing you with products that meet your boating needs and to this end we need customer feedback. It is essential that we build a picture of how the product performs in different parts of the World. Some areas will need to recoat their stern gear more frequently while others may get an entire season or more from one application. This difference is normal for any type of antifouling and different makes perform better in some areas than others. Whilst we are more than confident that Propshield will easily tackle the very worst of fouling it will be extremely helpful to you, our customer, that we can provide a more accurate application guide depending on your locale. We will endeavour with your help to build a map of the types of fouling regions to determine what coating regimes will be required in different areas. We hope you appreciate that we can only test in so many places  to determine an approximate coating regime and we have done this in very high fouling areas.

We are aware that oysters are a problem in certain areas and we are undertaking a programme of research that will determine its effectiveness within these regions for this type of contamination.
