Sonic Sustainability: How BPS Marine is Changing Hull Protection

Every captain knows the story. You haul out the yacht, scrape off the barnacles, repaint the hull, and watch as—months later—marine growth creeps back. Fouling is relentless, a battle as old as boating itself. Algae, barnacles, and biofilm—tiny nuisances that turn into performance-eating monsters if left unchecked.

It’s more than cosmetic. A fouled hull adds drag, guzzles fuel, strains engines, and steals knots off your cruising speed. The usual fix? Chemical antifouling paints—effective, yes, but packed with biocides and heavy metals that leach into the sea, harming marine life and degrading water quality and also demands routine fresh coats of antifouling paint.

We believe there’s a better way.

Our latest discovery in the biofouling space: BPS Marine’s ultrasonic antifouling system — a quietly brilliant technology that’s changing how captains and owners keep their hulls clean. Their ultrasonic antifouling technology protects hulls not with toxins, but with sound. It’s a clean, clever, and quietly transformative solution now finding its place aboard yachts around the world.

The Science Beneath the Surface

So how does it work?
The system uses a network of compact ultrasonic transducers mounted inside the hull. These emit high-frequency sound waves—imperceptible to humans and marine mammals—that travel through the hull material and into the surrounding water.

Each pulse creates microscopic vibrations across the surface, making it impossible for algae and barnacle larvae to attach. No chemicals, no scraping, no repeat and costly bottom paint jobs—just a silent hum of protection operating 24/7.

Think of it as creating a “hostile acoustic environment” for marine growth. The system prevents fouling from ever starting, rather than trying to remove it after the fact—a true proactive approach to hull maintenance.

Performance You Can Measure

A clean hull glides more efficiently, and the gains are significant. According to BPS Marine’s Training 2025 data, a 50-foot cruiser equipped with a BPS system can save over $9,000 in maintenance and service costs every two years. That’s fewer diver visits, fewer haul-outs, and longer paint life. But it’s not just about money—clean hulls reduce drag, which in turn improves speed and fuel efficiency. Many owners report noticeable improvements in handling and cruising range, all without altering their vessel’s look or performance.

“It’s like having an invisible diver working for you,” one captain said after installing the BPS-4 system. “Except this one never sleeps.”

Eco-Friendly by Nature

Traditional antifouling methods rely on chemicals that slowly poison marine ecosystems. BPS Marine’s system, by contrast, is completely non-toxic. No copper, no zinc, no microplastics—nothing enters the water.

Because the technology keeps the hull clean without friction or coatings, it also reduces the release of paint particulates into marinas and bays, one of the major sources of micro-pollution in coastal environments.

For environmentally conscious owners, this is a major win. Cleaner hulls mean less fuel burned and fewer emissions—proof that performance and sustainability can coexist beautifully.

“Hull protection should never come at the expense of ocean health,” says Andreas Schulz, BPS Marine’s founder. “Our ultrasonic systems let captains sail faster, cleaner, and more responsibly.”

Final Thoughts

The engineering is pure: elegant, efficient, and durable.
Each IP68-rated controller powers a series of fully submersible transducers, positioned to protect both hull and running gear. Systems come in configurations from 12V to 24V, making them suitable for everything from day cruisers to superyachts.

The power draw? Barely a blip—about one amp-hour at maximum output. The system even monitors your battery levels and adjusts automatically to avoid draining. Installation requires no drilling, no through-hull fittings, and integrates seamlessly into existing electrical setup. And every unit is backed by a lifetime warranty—a rare promise in the marine electronics world.

For yacht owners and captains, BPS Marine’s ultrasonic antifouling represents something special: real innovation with real-world benefits. It saves money, boosts performance, and protects the environment—all while operating silently beneath the surface.

It’s an upgrade you don’t see, but you’ll feel every time you open up the throttles and the hull glides effortlessly through clean water.

Because sometimes, the smartest technology is the one that just works—quietly, continuously, and without compromise.
