Foulfree system endorsed for stabilisation equipment

Humphree and Propspeed have announced a strategic partnership focused on protecting performance below the waterline, with Humphree endorsing the use of Propspeed’s Foulfree Multi-Surface System on its fins and interceptors.

The collaboration brings together Humphree’s stabilisation technology with Propspeed’s biocide-free foul-release coating, designed to help protect critical underwater components in demanding marine environments.

By helping to prevent marine growth accumulation on fins and interceptors, Foulfree Multi-Surface is intended to support consistent handling, improved fuel efficiency and reliable stabilisation performance throughout the season. The system may also reduce the need for in-water cleaning and maintenance.

Protecting performance below the waterline

Foulfree Multi-Surface provides a solution that supports efficiency without compromising handling, and we’re confident our customers will appreciate the benefits it brings to their stabilization equipment.

Johan Cavefors, Director Sales Marine Professional, Humphree.

We’re proud of the continued evolution of our foul-release coatings. Working alongside leading manufacturers like Humphree reinforces our mission to protect performance below the waterline. Foulfree Multi-Surface is designed to shield all Humphree fins and interceptor product lines without compromise, providing efficient operation throughout the season while preserving OEM engineering aesthetics, through a clear, non-invasive coating system.

Marcus Hamilton, CEO, Propspeed

The partnership forms part of Propspeed’s wider approach of working with technically aligned marine partners focused on quality, performance and responsible marine practices. It follows existing affiliations with Cranchi Yachts and Camber Marine, supporting underwater asset protection across new build and refit applications using Humphree’s product line.

Propspeed’s product range includes Propspeed for running gear and underwater metals, Foulfree Multi-Surface System for non-metal substrates, Lightspeed for underwater lighting and Stripspeed, a foul-release coating remover.
