Eight submersible transducers flood the underwater surfaces with ultrasonic energy that stops barnacles, slime, and weed before they can take hold, protecting boats up to 80 feet.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eBottom growth is the tax you pay for leaving a boat in the water. Barnacles, slime, and weed build up on the hull, drives, and running gear, and they cost you speed, fuel, and hours of scraping. The BPS Marine ultrasonic antifouling system takes a different approach than bottom paint. Instead of coating the hull with something that wears off and needs redoing, it uses ultrasonic energy to keep the growth from ever getting a grip. This is the 8-transducer 12-volt system, sized for larger boats, up to about 80 feet, or under 52 feet with inboards or sail drives.\u003c\/p\u003e\n\u003cp\u003eHere's how it works. Eight submersible transducers mount inside the hull, and the control module drives them with a multi-frequency ultrasonic sweep in the 20 to 42 kHz range, up to 60 watts of transducer output. Those ultrasonic waves create a microscopic layer of moving pressure across the wetted surface of the hull. Barnacle and algae larvae need a calm surface to settle and attach to, and that constant ultrasonic agitation denies it to them. The growth simply can't establish itself. It's continuous, running quietly in the background whenever the system is powered, protecting the boat 24\/7.\u003c\/p\u003e\n\u003cp\u003eThe eight-transducer count is what makes this the system for bigger boats. Ultrasonic energy spreads out from each transducer over a certain area, so a longer hull with more wetted surface, plus drives, rudders, and stabilizers to protect, needs more transducers to cover it all. Eight units let you place coverage where it matters across a large hull, including the hard-to-reach areas that are the worst to clean by hand and the easiest to neglect. Those running gear surfaces and tucked-away spots are exactly where growth loves to hide, and this reaches them.\u003c\/p\u003e\n\u003cp\u003eThe big advantages over traditional antifouling are what make this worth it. There's no bottom paint, so no chemicals leaching into the water, no annual haul-out and repaint, and no toxic ablative coating wearing off into your marina. It's genuinely eco-friendly. And because it prevents growth rather than poisoning it after the fact, you keep a cleaner hull, which means better performance and fuel economy and far less time spent scrubbing. BPS backs the system with a lifetime warranty, which tells you what they think of its durability.\u003c\/p\u003e\n\u003cp\u003ePower draw is modest for what it does. It runs on 12 volts and averages about 2 amp-hours, so it's not a heavy load on your house bank, and it's designed to run continuously. In the box you get the BPS-8 control module with an integrated power cable, eight transducers each with a 15-foot cable, four additional 15-foot extension cables for flexible placement on a big hull, two epoxy kits for bonding the transducers in place, and a printed installation and operation manual.\u003c\/p\u003e\n\u003cp\u003eIt's worth understanding the payback over a few seasons. A boat that stays clean runs at its designed speed and burns less fuel, and you avoid the recurring cost and downtime of hauling out for a bottom job every year. Factor in the labor you'd otherwise spend, or pay someone else to spend, scrubbing a fouled hull, and an ultrasonic system genuinely earns its place. Install it once, let it run, and it quietly protects your investment year-round while you spend your time boating instead of scraping.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Owners of larger boats up to 80 feet, or under 52 feet with inboards and sail drives, who keep their boat in the water and are tired of the cost, hassle, and environmental downside of bottom paint and constant cleaning. If you want a set-and-forget way to keep your hull and running gear clean, protect your performance, and skip the yearly bottom job, an ultrasonic system like this pays for itself in saved haul-outs and fuel. This is the version built to protect a big hull properly.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e8 submersible ultrasonic transducers for large-hull coverage\u003c\/li\u003e\n  \u003cli\u003eProtects boats up to 80 ft (under 52 ft with inboards\/sail drives)\u003c\/li\u003e\n  \u003cli\u003eMulti-frequency ultrasonic sweep, 20 to 42 kHz, up to 60 W output\u003c\/li\u003e\n  \u003cli\u003ePrevents barnacles, slime, and weed with no paint or chemicals\u003c\/li\u003e\n  \u003cli\u003eReaches hard-to-clean drives, rudders, and stabilizers\u003c\/li\u003e\n  \u003cli\u003eContinuous 24\/7 protection, eco-friendly, no toxic coatings\u003c\/li\u003e\n  \u003cli\u003eLow average draw of about 2 Ah on 12V\u003c\/li\u003e\n  \u003cli\u003eLifetime warranty on the system\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized BPS Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow does ultrasonic antifouling work?\u003c\/summary\u003e\n    \u003cp\u003eThe transducers flood the wetted surfaces of the hull with a multi-frequency ultrasonic sweep.
