Collection: Antifouling Systems

Keeping a hull, running gear, and underwater electronics free of barnacles, algae, and slime is a real maintenance challenge, and this category covers two distinct approaches. BPS Marine's ultrasonic systems use transducers mounted to the hull to emit continuous low-frequency vibrations that inhibit biofouling without antifouling paint or biocides. The key variables to sort out before buying are the number of transducers your boat needs, which scales with hull length and complexity, and your vessel's DC voltage, since BPS Marine offers both 12VDC and 24VDC lines. Propspeed takes a different approach with its Foulfree coatings, which are applied directly to transducers or across multiple surfaces to create a slick, non-stick barrier. Quick's cabling accessories are designed for use with compatible TCD controllers, so check compatibility with your existing setup before ordering.

For a smaller single-hull boat with straightforward geometry, a one or two transducer ultrasonic system is typically the starting point, while larger vessels or those with complex hull forms warrant stepping up to four, six, or eight transducers for full coverage. If your primary concern is protecting sonar transducers or props rather than the full hull, Propspeed's Foulfree products are worth a close look as a targeted, paint-free solution. Outdoors Marine stocks all three brands as an authorized dealer, so you are getting genuine products backed by manufacturer warranties.
