Ultrasonic Antifouling Technology

Continuous Antifouling Protects your Vessel from Fouling.

Ultrasonic antifouling works by using sound waves to physically repel fouling organisms away from the surface before they can permanently attach. As a bonus, the higher frequency band of ultrasound also disrupts the reproductive cycles of certain types of bio-fouling.

Hull Shield systems operate similar to a stereo and speakers. The controller sends ultrasound signals to transducers attached to the hull or running gear, the transducers receive the high-frequency signals, transforming them into ultrasonic pulses.

Each pulse creates a microscopic shockwave that runs across the hull and drive gear. These ultrasonic waves work to ablate, loosen, and repel fouling which is contacting the hull and drive surfaces. When used in conjunction with an ablative bottom paint, Hull Shield systems are the most effective and long-term antifouling solution available.

Ultrasonic Antifouling Hull Coverage

Stay cleaner for longer while extending the functional lifespan of your bottom paint.

Each transducer provides approximately 200sqft of protected underwater surface area. A rough estimate of your underwater surface area can be calculated by doubling your draft, adding it to your beam, then multiplying by your LWL (length at water line)

Ultrasonic Antifouling for Drives

Not just for hulls – Hull Shield can protect your drives and running gear too!

Drives are isolated from the hull by motor mounts, gaskets, seals and other insulative materials that block ultrasound from passing to shafts, props, and rudders. Because of this, the drive system requires dedicated transducers to gain the most benefit from ultrasonic anti-fouling. Inboards, pods, sterndrives, and sail-drives can all be fitted with a transducer to enable full anti-fouling protection. Rudders are isolated from the hull in the same way as the drives and also require a dedicated transducer.

One transducer can provide dedicated protection for any single isolated part. Examples of isolated parts are drive shaft & props, rudders, exterior engine brackets, struts, & stabilizers. Because these parts are isolated from the hull and each other, a transducer is required for each independent part.

Have a 24V Battery System? We Have you Covered...
Victron Energy - Our Tested & Approved Recommendation

Hull Shield HD systems produce ultrasound from a 12V battery system input (compatible with most boat battery systems). If you have a vessel which does not have 12V battery system voltages available, then we have you covered.

Connecting Hull Shield HD systems to a 24V battery system can be done simply with a 24/12 power converter. The Victron Orion 24/12 converter is our “tested and approved” recommendation and supplies clean and efficient power to all of our HD products. The Victron Orion 24/12 is affordable option and can be purchased with your order directly through us.

We also recommend to have a Victron 24/12 BatteryProtect placed inline between the 24V battery system and and the Victron Orion converter. The BatteryProtect can automatically turn-off the converter if it senses the 24V battery system voltage levels are below a preset threshold. This can protect the batteries from being drained if they are not being maintained.

Benefits of Ultrasonic Antifouling

Continuous Antifouling

Hull Shield systems effectively work 24/7 to repel most types of marine fouling.

Improve Performance

A clean hull has less drag, improved fuel efficiency, and increased top-end speed.

Save Money & Time

Spend less money and time with fewer haul-outs, bottom painting, and abrasive cleaning.

Easy Installation

Installation is straight-forward, easy and does not require special tools.

Environmentally Friendly

Use less applications of toxic bottom paint while reducing environmental impact.

Increase Resale Value

Boats having automated anti-fouling hardware have increased resale value.

We have been using Hull Shield for six months on our 36. The boat was dove in March to clean the motor mounts and check on the bottom. I can affirm the bottom was clean with no hard or soft growth whatsoever. Also I will say that the folks at the company are genuine, and more importantly, boaters themselves! It makes a huge difference!

My experience with Hull Shield is simply outstanding! I've been on the search for so long to have a solution like Hull Shield provides! Truly amazing product, technology, and innovation. It reduced drastically the amount of decay & particles that sit on the hull.

I have Hull Shield on my 2022 - 270 Premier Grand Entertainer. At first I was a little skeptical about the claims but I needed a solution that would allow me to keep my boat at my dock without the expense and maintenance of an anti-fouling bottom coating. I am now a fervent believer in the abilities of Hull Shield to keep my boat marine growth free.

We are putting one on our 54; we already had it on our 44. Hull Shield. It's amazing!! Pays for itself.

Today, after not hauling or cleaning in 4 months there was not a single, solitary barnacle on the hull itself; not one! The tabs were growing a nice crop of barnacles, but the bottom of the hull is as clean as the day it was painted. Today was an eye-opener. Am very pleased with the results so far - have exceeded my expectations.

I have Hull Shield, bottom paint, boat in water, diver cleans boat. Due to the trip to the Keys and my lower unit breaking down, my 36 was in the water for over 3 months without being cleaned by a diver. I had diver clean bottom. He came up and said 'There is nothing on this boat. 'How long has it been in water?' He was shocked at the time. He shook his head and said, 'I've never seen anything like this.'

We were thrilled to have our Hull Shield installed on our Aquila 44 power catamaran, One Eye Dog! Since it's installation we are already noticing a difference. We are currently traveling the waters of South Carolina where divers clean boats about every three weeks. While we have a bit of slime from the, we are not seeing any growth. We couldn't be happier with the results.

Yes, definitely get Hull Shield! You should see my boat compared to the ones around me in the marina. The only growth I see on mine is at the back around the engine mount and cables etc.

I have been running hill Shield for two seasons and I am impressed. I do not have bottom paint on my boat, I do two short hauls a season and have not had one barnacle on the hull. I had an issue with the system on Labor Day weekend last year and Gabe called me back on the holiday weekend and walked me through trouble shooting. Great product will always have one on my boat!
