As a company dedicated to protecting our oceans, Propspeed continues to provide the industry with high-performance products to make superyachts more efficient and economical. One of these products is the propeller and running gear foul-release coating system, Propspeed, which has been specially formulated to prevent marine growth from bonding to metal surfaces below the waterline.Photo: Charl van Rooy / SuperYacht TimesFouling below the waterline and growth on underwater lights on any vessel damages both the marine ecosystems, the vessel’s performance and fuel costs. Together with Propspeed, we share the details of their solutions for underwater assets and find out why the Propspeed coating system, Lightspeed and Foulfree are a vital part of boat maintenance.
Propspeed was developed in the Bay of Islands, New Zealand after a sport fisherman collaborated with a local boat painter to develop what is now globally recognised as the leading and original foul-release coating to protect precious underwater assets such as propellers, shafts, struts, sail drives and rudders.
Propspeed uses a two-component etching primer which bonds to the metal substrate and a clear silicone topcoat for an ultra-smooth outer layer. Combined, they provide an integrated coating system that stays firmly adhered to the running gear and dramatically reduces the opportunity for fouling to occur. By deterring marine growth, Propspeed avoids any added weight and increased drag that reduces a vessel’s speed and fuel efficiency.
Propspeed also protects underwater metals from corrosion, which occurs through electrochemical reactions with the metal’s environment, by isolating the metal from the oxygen and the electrolyte, as well as limiting the exchanges between the ions and the gases contained in water and metal. In short, if a reaction can’t occur, there will be no corrosion. It is also important to ensure your protective coating is paired with the right anode to ensure efficient cathodic protection and the best coating performance and longevity.

By generating light and heat, underwater lights are favoured by marine growth such as barnacles, oysters, mussels, seaweed and algae which all interfere with an underwater lights’ ability to emit light. Efforts to remove this growth, barnacles in particular, can damage delicate lighting components as barnacle glue is the most powerful adhesive in nature and six times more powerful than any manmade glue.
Conventional antifouling paint is unsuitable for underwater lights due to the lack of transparency that interferes with light transmittance, whereas Lightspeed harnesses the science behind Propspeed to provide an effective and fully transparent solution. By containing an adhesion promoter, Lightspeed ensures the coating lasts for up to 24 months, significantly reducing maintenance time and costs.
The revolutionary and certified foul-release coating, Foulfree, deters marine growth from transducers which can affect the level of detail on the sonar image received and the accuracy of the vessel’s signal transmission. Transducers perform best with minimal turbulence over their surface during operation and so, by keeping transducers free of marine growth, the flow of water over the transducer face is streamlined and guarantees the best results.
