About Hull Shield

Ultrasonic Antifouling - How it Started

Discover the journey of Hull Shield – from problem to solution. Hull Shield ultrasonic antifouling products were developed to help boat owners just like you.

How Ultrasonic AntiFouling Works

Hull Shield products protect vessels against the effects of marine biofouling. Our ultrasonic systems use of ultrasound to limit and restrict the ability of microorganisms to attach to surfaces that are exposed to raw seawater. Ultrasound wave energy is transmitted through these surfaces to create an ultra-thin layer of high pressure between the protected surface and the surrounding water. The resulting area of high-pressure is a barrier which microorganisms cannot pass through.
 
In simpler terms, each pulse of ultrasound induces a small vibration in the surface material. These micro-vibration repel fouling organisms away from the material, keeping it cleaner for longer.

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 a 50 foot Absolute in Charleston SC. I used to have a diver come and remove barnacles twice a month... I was skeptical but it really works.

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!
