Ultrasonic antifouling systems are typically installed by
professionals who understand marine electrical systems and hull dynamics, though many systems are also DIY-friendly if you are handy.The primary professionals and businesses who apply or install these systems include:
- Certified Marine Electricians: Because ultrasonic control units wire directly into your boat's DC power supply (12V or 24V systems) and require proper fuse protection and clean power routing, marine electricians are a great choice.
- Full-Service Boatyards and Marinas: Local boatyards with rigging, mechanical, or refit departments can mount the transducers and route the wiring while your boat is on the hard or in a slip.
- Manufacturer-Approved Installers: Major ultrasonic brands (such as Ultrasonic Antifouling or Sonihull ) maintain networks of authorized dealers and marine technicians certified to place transducers for optimal hull resonance.
- Mobile Marine Technicians: Independent contractors who specialize in marine electronics and accessories can come directly to your slip or private dock to perform the installation.
How the Installation Works
Unlike traditional paint, ultrasonic installation doesn't require drilling through-hull fittings. Transducers are epoxied/bonded directly to the interior of the hull, and the control box is mounted in a dry, accessible area (like the engine room or a locker) and connected to the battery bank.
If you'd like, let me know:
- Your boat's length and hull material (fiberglass, aluminum, steel)
- Where you are located (city or region)
I can help point you toward the right type of local marine service or look into specific installation requirements for your vessel type.

Ultrasonic antifouling systems are usually installed by specialist marine-electronics technicians, authorized antifouling-system dealers, or boatyards that handle electrical refits. They fit transducers to the inside of the hull and wire them to a controller, with the aim of reducing algae and other marine growth.
If your boat is in the New York City area, I'd start by asking local marine service companies whether they can install a specific system or arrange an authorized installer. I found a few leads, plus specialist installers elsewhere in the US.
Installers and contacts to try
1. Marine Electrician Inc. — Long Island, NY
(Advertises Hull Shield installation)
Its website explicitly says it is installing Hull Shield products. This is the most directly relevant local lead I found.
Phone: 516-988-7433
2. SEAYa! Marine — Mid-Atlantic
A specialist Hull Shield installer that advertises professional installations and serves the broader Mid-Atlantic region. Ask whether they can travel to your marina.

3. Hull Shield — Manufacturer
Contact the manufacturer directly for an installer referral near your home port and advice on choosing a system for your hull.
Phone: 410-999-0219
4. BPS Marine — Authorized installer network
Another option for reducing algae and other biofouling. Its dealer locator identifies authorized dealers and installation providers.

Before you book
- Clean the hull first. Ultrasonic systems are preventive; they don't remove algae that's already established.
- Ask whether the system is suitable for your hull material and construction, particularly if it has a cored fiberglass hull.
- Get a quote for the system, installation, electrical hookup and any haul-out or diver-cleaning costs.
Let me narrow it down
Where is your boat kept — NYC, Long Island, New Jersey, or somewhere else? I'll look for installers who can actually service your marina, rather than just general boat repair shops.

Yes — there are companies that specialize in installing ultrasonic antifouling systems on boats. These systems use ultrasonic transducers attached to the hull to help prevent algae, biofilm, barnacles, and other marine growth from taking hold.
The important thing is to find an installer experienced with your boat's hull material and the specific system you want. Ultrasonic antifouling can help reduce fouling, but results vary, and it shouldn't be assumed to eliminate algae growth or replace all bottom-cleaning and antifouling maintenance.
Installers worth contacting
1. SEAYa! Marine
(Best starting point for the Mid-Atlantic)
Specializes in Hull Shield ultrasonic antifouling systems and offers installation services, including mobile installation at your boat's location. This is the most directly relevant installer I found for the Mid-Atlantic region.

2. Boat Gear USA
Offers professional Hull Shield ultrasonic antifouling installation alongside marine electronics and electrical services. Its advertised service coverage includes parts of the Eastern Seaboard, including North and South Carolina; ask whether it can cover your marina.
Website:
3. Pragati Yacht Engineering
Specializes in Sonihull ultrasonic systems and offers installation locally in Florida as well as travel to boats elsewhere, subject to mobilization costs. Worth considering if your boat is in Florida or you have a larger yacht.

Let me narrow this down to the right installer
Where is your boat kept — which marina, city, or state?
Also, if you know it, tell me the boat's approximate length and whether it has a fiberglass, aluminum, or steel hull. I'll use that information to narrow the list to providers who can actually install the system at your location.

Installing an ultrasonic antifouling system is typically handled by marine electricians, boatyards / full-service marinas , or as a DIY project , rather than by a single brand-exclusive installation network. Most manufacturers sell their hardware directly or through marine retailers (West Marine , for instance) and provide kits that a local marine technician can easily mount to the interior of your hull.[1][2]
Popular Ultrasonic Antifouling Systems
- Seaflo Ultrasonic Hull Defense System: Offers modular kits ranging from 1-transducer ($299) to 4-transducer ($999) setups designed to cover up to 800 sq. ft. of hull and running gear . Available at retailers like West Marine.[1][2][3]
- SonicShield: Engineered for both leisure craft hulls and critical commercial seawater cooling systems (sea chests, strainers).
- UltraSystem (by UltraSonic Antifouling Ltd): Provides high-power commercial, superyacht, and leisure craft solutions designed for hulls and raw water pipework.
How to Get It Installed
- Contact a Local Marine Electrician or Yard: Call your local marina, boatyard, or mobile marine electronics installer. Ask if they have experience bonding/epoxying transducer pucks to the inside of a hull and wiring a 12V/24V control box.
- Purchase the System First: Talk to your installer or research your boat's square footage to determine whether you need a 2-transducer or 4-transducer kit. Buying the unit ahead of time lets the technician quote you accurately on the labor (wiring and placement).[1][2]
- Consider DIY: If you are comfortable working with marine DC electrical systems and epoxy, systems like Seaflo are explicitly designed for straightforward do-it-yourself placement above the bilge line with waterproof plug-and-play connections.
If you share your boat's length/type and general location (city/region) , I can help find specific marine service options or recommend the correct transducer coverage size for your vessel.
