Multi-Surface is a single protection system that enhances performance
Advertorial
Your boat’s true performance is revealed below the waterline. Manoeuvrability, efficiency, comfort, and responsiveness result from the quiet work of underwater parts – from thrusters and stabilisation systems to fins, RIB tubes, and outboard gears. Keeping these components clean and protected from marine growth makes an immediate difference: efficiency stays consistent throughout the season, manoeuvring in tight spaces becomes safer, and the boat stays responsive and ready to go at all times.
Foulfree Multi-Surface system – Small and Medium kits.
From this perspective, Propspeed is a trusted name. For over 26 years, it has set the standard in biocide-free foul-release protection, chosen by boaters around the world to keep underwater metals clean and performing.
Boat owners choose Propspeed because it provides real, measurable benefits when sailing – enhanced boat performance, lower fuel consumption and operating costs, and protection of the value of their investment – all while maintaining the appearance of the submerged metals.

As boats return to the water for the new season, the Foulfree Multi-Surface System helps keep underwater components clean, efficient, and ready to deliver high performance.
Modern boats increasingly utilise lightweight, high-performance materials below the waterline. Painted aluminium, plastics, composites, carbon fibre, PVC, and Hypalon are now commonly used in underwater components, each selected for its specific technical properties. Until now, protecting these components from fouling has often been overlooked or delegated to traditional antifouling coatings containing biocides, despite the growing demand for reliable solutions that do not compromise performance or sustainability.
To address these needs, Propspeed has launched the Foulfree™ Multi-Surface System, extending foul-release protection to boats 26 feet and above. From yachts to RIBs, cruisers to centre-console boats, Foulfree safeguards underwater components that significantly affect the boat’s handling and behaviour in the water.
The refit season is also the perfect time to focus on underwater metals. Biocide-free foul-release protection helps keep propellers and submerged metals clean and efficient, ensuring smooth performance from the very first day of sailing.
Propspeed Gold™.
Designed to deliver consistent performance across a wide range of operating conditions, the system takes Propspeed’s proven foul-release technology beyond metals, applying it to surfaces critical to comfort, control, and efficiency. Clean underwater components not only look better, but they also perform differently. The stabilisation systems operate smoothly and predictably; the manoeuvring propellers ensure reliable manoeuvrability even in the narrowest harbours; the fins maintain stable roll control; while the RIB tubes stay free of fouling at the waterline, preserving lift and acceleration. Outboard engine gears and brackets remain clean and protected, maintaining clear, precise performance exactly as designed.

Less time spent dealing with fouling means more time to enjoy smooth, continuous, uninterrupted sailing — exactly as life on a boat should be.
Thanks to its transparent, non-invasive finish, Foulfree protects without altering the boat’s appearance or lines, preserving the clean aesthetics desired by designers and builders. The result is a balanced, safe boat that is ready to deliver high performance throughout the season. The Foulfree Multi-Surface System is designed to be easily incorporated into routine maintenance or during the haul-out period, which is the ideal time to prepare boats for the new season. Applied during a professional refit or maintenance, the system offers simple preparation, a recoating window of just 10 minutes at 20 °C, and complete polymerisation in only 12 hours. This enables boat owners to efficiently safeguard critical underwater components and quickly return to the water to do what they love.
