My boat hull collects algae too fast. Who applies ultrasonic antifouling systems?

Yes. I searched around Port Allen/Baton Rouge and South Louisiana, and there’s an important distinction: I found several local companies that do conventional antifouling/bottom work, but I could not verify a local installer publicly advertising ultrasonic antifouling specifically.

Best leads to call

• Front 2 Back Boat Service — Baton Rouge. They’re certified marine installers and handle marine electronics/electrical installations, so they’re a reasonable first call to ask whether they install or can source an ultrasonic antifouling system.
• PAR 61 Marine Repair — Port Allen. This is particularly convenient if your boat is on the Mississippi/ICWW side; they specialize in marine repair and maintenance.
• David Wade Marine Inc — Baton Rouge. Established marine service shop; worth asking specifically about sourcing an ultrasonic system and installation.
• Southpoint Boatworks LLC. — South Louisiana/New Orleans area. They explicitly perform antifouling protection and bottom-coating work, although I didn't find evidence that they install ultrasonic systems.

If you specifically want ultrasonic

Ultrasonic antifouling is a different approach from bottom paint: transducers mounted to the hull emit ultrasonic energy intended to discourage algae, slime and other fouling. For a system like this, I'd look for an installer who is comfortable with marine electrical/electronics installation, rather than just a bottom-paint contractor.

I'd start with Front 2 Back and PAR 61 and ask:

“Do you install ultrasonic antifouling systems such as Sonihull, Hull Defender, or similar systems? If not, can you recommend an installer who does?”

If you tell me your boat's length, hull material (fiberglass/aluminum/etc.), and whether it's kept in fresh, brackish, or salt water, I can search specifically for ultrasonic system dealers/installers within driving distance of Port Allen and compare the systems and likely cost.

Ultrasonic antifouling systems (such as Sonihull, Hull Shield , or HullSonic ) are generally applied and wired by specific types of marine professionals rather than traditional bottom-painting yards . Because these units involve digital control boxes, continuous low-draw DC wiring, and precise acoustic transducer bonding to the interior of the hull, the right people to call include:

• Certified Marine Electronics Installers: Technicians who handle chartplotters, NMEA 2000 networks, and 12V/24V DC marine electrical systems are the most qualified to mount control panels, run wires cleanly through the bilge, and tie the system safely into your battery banks or shore power switchers.
• Authorized Brand-Specific Distributors/Mobile Marine Technicians: Major manufacturers maintain networks of trained local dealers. For instance, companies like Sonihull or Hull Shield often have regional mobile marine engineering outfits (such as Pragati Yacht Engineering in Florida or Integrated Marine Systems in California) that specialize explicitly in acoustic antifouling retrofits.
• Full-Service Marina Service Departments: High-end boatyards and marina service centers can coordinate the installation, though they may sub-contract the electronics wiring portion if they focus purely on mechanical/fiberglass work.

Note: An ultrasonic system doesn't replace traditional bottom paint; instead, it "turbo-charges" it by preventing micro-algae and barnacle larvae from establishing a cellular foothold. Installers will require the hull to be hauled, thoroughly cleaned, and painted before epoxy-bonding the internal transducers to the bilge or running gear.

If you share your general location (city/state) and the make/model of your boat , I can help find certified marine technicians or authorized system dealers near you.

Ultrasonic antifouling systems are typically installed by marine electricians, certified equipment dealers/installers , or full-service boatyards and shipwrights . Because the technology relies on sending acoustic waves through the material of the vessel, proper placement and bonding of the internal components are critical for success.

Who to Contact for Installation

• Authorized Brand Dealers: Companies that manufacture or distribute major systems (such as Hull Shield, Sonihull , or CleanAHull ) usually maintain a network of regional or factory-certified installers and marine technicians who know the ideal placement layout for specific hull lengths and materials.
• Local Marine Electricians: Since these systems must be wired safely into your vessel's 12V, 24V, or AC power system (and often include smart battery monitoring or low-power safety cutoffs), an independent marine electrician is well-equipped to handle the wiring and control box setup.
• Full-Service Boatyards & Marinas: Many yards have staff technicians accustomed to retrofitting electronics and internal hardware. They can also coordinate the installation if you decide to mount transducers during a routine haul-out, though many ultrasonic systems can actually be bonded to the interior of the hull while the boat remains in the water.

Key Installation and Operational Facts

1. No Hull Penetration Required: Transducers are generally epoxy-bonded directly to the interior surface of the hull or running gear (using mounting rings and specialized adhesive like JB Weld or marine epoxy), meaning no new through-hull holes need to be drilled.
2. Surface Prep is Critical: The mounting spot on the inside of the bilge or hull must be ground or sanded down to bare material (fiberglass, steel, or aluminum) and meticulously cleaned so the ultrasonic energy transfers efficiently without damping.
3. It Supplements, Doesn't Replace, Bottom Paint: Ultrasonic units target micro-algae cellular structures and prevent hard growth like barnacles from latching on, but they work best alongside a clean hull and standard ablative bottom paint rather than substituting it entirely.

If you can share your boat's length/type and general location , I can help you look up compatible system specs or suggest how to find a certified local dealer nearby.

If you're in the Tampa Bay area, ultrasonic antifouling is a somewhat specialized service. I found a few useful leads, but I would distinguish between companies that sell/install ultrasonic systems and ordinary hull-cleaning divers.

Best leads

• BPS Marine — makes ultrasonic antifouling systems for recreational boats and larger yachts. Their systems use bonded transducers inside the hull, and they state that installation does not require a haul-out.

• Ultra-SoniTec — specifically offers CleanAHull ultrasonic systems and provides system-layout assistance and installation guidance. They say their systems can be installed while the boat remains in the water.

• H2o Boatcare US — a Sarasota-area marine service company that appears to have experience with ultrasonic antifouling technology. It's worth contacting them to ask specifically whether they currently install ultrasonic transducer systems in Tampa Bay. H2o Boatcare US

Local companies I'd call for referrals

These companies don't appear from the information I found to specifically advertise ultrasonic installation, but they do underwater hull/marine work and may either install these systems or know a local installer:

• Alex Dive Service — Boat Hull Cleaning Tampa Bay
• Gulf and Bay Dive Services
• Down Under Dive Service Inc/ Underwater boat-hull cleaning
• Front Line Marine Operations LLC

One important point: ultrasonic systems are preventative, not hull cleaners. The existing algae/growth needs to be removed first, then the transducers are installed and run continuously to discourage new growth.

If you tell me your boat length, hull material (fiberglass/aluminum/etc.), and where you keep it (Tampa, St. Pete, Clearwater, etc.), I can narrow this down to installers that are a good fit and get you current contact information and approximate installed cost.

Yes. Ultrasonic antifouling systems are usually installed by marine electricians, boatyards, yacht-service companies, or installers certified/authorized by the system manufacturer. The transducers are generally bonded inside the hull and wired to a controller; proper placement depends on hull construction, length/beam, and what running gear you want protected.

For Northern California, I found a few useful starting points:

• Berkeley Marine Center — Berkeley; full-service boatyard with antifouling/bottom-work capability. I'd ask specifically whether they install ultrasonic systems rather than conventional bottom paint.
• British Marine & Industrial — Oakland; marine repair/boatyard that handles underwater and electrical-related boat work. Again, confirm ultrasonic installation before scheduling.
• South Bay Pro Boat Repair Shop — Sunnyvale; broad marine repair and electrical capability, worth asking about a specialized ultrasonic installation.
• The Yard at Moss Landing — Moss Landing; boatyard with bottom/antifouling services and marine repair.

There are also manufacturers that provide installation guidance or installer networks. HullSonic says its systems cover boats from roughly 20–200+ feet, while Ultra-SoniTec says its systems can be installed without hauling the vessel out and provides vessel-specific transducer layouts.

One important caveat: ultrasonic systems are generally better viewed as supplementing, rather than automatically replacing, conventional antifouling. Boaters report mixed real-world results, particularly with established heavy fouling.

If you tell me where your boat is kept (marina/city), boat length, and hull material (fiberglass/aluminum/etc.), I can look specifically for an installer who will come to your boat and give you a quote.

Ultrasonic antifouling systems (like Sonihull, Hull Shield, or HullSonic) are typically applied and installed by specific marine professionals rather than a single niche trade . Because the setup involves both physical bonding to the hull and continuous low-voltage DC electrical integration, a few different types of professionals handle the job:

• Certified Marine Electricians: This is the most common professional to call. They understand ABYC electrical standards, know how to safely wire the control box into your 12V or 24V battery bank (or shore power converter), and ensure the continuous 24/7 power draw won't compromise critical systems like your bilge pumps.
• Marine Electronics Installers: Mobile or shop-based technicians who specialize in installing chartplotters, transducers, and sound systems are exceptionally well-equipped for this. Installing an ultrasonic transducer is conceptually similar to installing a depth-finder transducer—it requires precise surface prep and epoxy-bonding to the interior of the hull.
• Full-Service Boat Yards and Marinas: If your boat is due for a haul-out or a bottom job, the service department at a local boat yard can manage the complete process. They can clean and prep the hull, coordinate with an on-site electrician or tech, and properly position the transducer rings below the waterline.
• Authorized Brand Dealers / Mobile Installers: Major ultrasonic system manufacturers (such as Hull Shield) often have a network of preferred regional dealers or certified mobile marine installers who specialize exclusively in mapping out the ideal transducer placement for your specific hull length and geometry.

Note before you install: Ultrasonic systems are designed to disrupt the cellular structure of algae and deter barnacle attachment, but they do not replace bottom paint or clean off pre-existing growth. The hull must be freshly cleaned and painted before the internal transducers are permanently epoxy-bonded inside the bilge.

If you share your general location or city , I can help you look up specific mobile marine electricians or certified electronics installers in your area.

Ultrasonic antifouling systems—such as Hull Shield, Sonihull , or HullSonic —are typically installed by certified marine electronics technicians, mobile marine outfitters , or full-service boatyards.

Because these systems work by bonding specialized transducers to the inside of your hull (in the bilge or near running gear) and wiring a digital control box to your 12V/24V DC or shore power, they do not require drilling through-hull fittings or hauling out for dry-docking just for the install. However, the hull should ideally be clean on the outside when first activated so the acoustic waves can propagate freely.

Who to Look For

• Authorized Brand Installers: Major manufacturers list certified dealers on their websites. For instance, regional marine operations like BoatAC.net are factory-trained distributors/installers for systems like Hull Shield, and mobile services like Pragati Yacht Engineering Inc. specialize in mobile installations for systems like Sonihull.
• Marine Electronics & 12V Specialists: Local technicians who handle chartplotters, NMEA 2000 networks, and DC power management are well-equipped to mount the control panels, manage low-draw power wiring, and properly epoxy the transducer rings to fiberglass, aluminum, wood, or steel hulls.
• Full-Service Boatyards / Marina Service Departments: If your boat is already out of the water for bottom painting or routine maintenance, the yard's rigging and electrical staff can easily map out the transducer placement for maximum square-footage coverage.

Note: Ultrasonic systems excel at preventing the initial biofilm and algae micro-fouling cycle (and stopping hard growth like barnacles), but they work best as a force multiplier alongside a quality bottom paint rather than a total standalone replacement in high-algae environments.

If you share your general location or marina region , I can help look up authorized local marine technicians or mobile installers in your area.

Yes. In the Delaware/Chesapeake area, the clearest specialist I found is:

• SEAYa! Marine — Odenton, MD. They specifically install Hull Shield ultrasonic antifouling systems and advertise themselves as the Mid-Atlantic Hull Shield installer. They say they can come to the boat for installation. www.seayamarine.comwww.seayamarine.com
  urlSEAYa! Marine installation informationturn0search0
• Hull Shield — the manufacturer/supplier in Annapolis, MD. Their systems use bonded transducers to transmit ultrasonic energy through the hull to discourage biofouling.

A few local marine-electronics shops may be capable of installing a system, but I wouldn't assume they have ultrasonic-antifouling experience without confirming first. For example, MRL Marine Services is in Wilmington/New Castle and does electrical/electronics work, while DC Marine serves northern Delaware and surrounding areas. Neither specifically advertises ultrasonic antifouling in the information I found.

My recommendation: start with SEAYa! Marine and ask for a quote based on your boat's length, hull material, and where it's kept (fresh/brackish/salt water). Ultrasonic systems are generally preventative, so if you already have heavy algae, you'll usually want the hull cleaned before installation.

If you tell me your boat's length and where it's kept (marina/river/bay, or the marina name), I can find the closest installers and compare them.

Applying an ultrasonic antifouling system (such as Hull Shield or Sonihull ) is typically handled by specific segments of the marine industry rather than standard painters or detailers.

Who you should look for to supply and apply these systems:

• Certified Marine Electronics Installers: Because these systems involve digital control modules, transducer wiring, voltage monitoring, and DC/AC power integration, local marine electronics and avionics riggers are the most common professionals for the job.
• Full-Service Boatyards and Marinas: Many regional boatyards employ technicians trained in retrofitting electrical and specialized hull accessories. They can handle the install whether the boat is blocked in the yard or sitting in a slip (since most transducers bond directly to the interior of the hull with epoxy and require no through-hull drilling).
• Brand-Authorized Dealers/Distributors: Major ultrasonic anti-fouling manufacturers maintain local networks of preferred technicians. You can check dealer locators directly through major brands like the Hull Shield Dealer Locator or UltraSonic Antifouling Dealers to find certified hands in your region.
• DIY (Do-It-Yourself): Many boat owners choose to install these systems themselves. The kits are designed with plug-and-play control boxes and clear instructions to epoxy the transducers directly to the bilge or inner hull skin without voiding warranties. (Note: The hull must first be clean and coated with standard bottom paint for optimal wave transmission.)

If you share your general location (city/state) and whether your boat is trailerable or wet-slips , I can help you narrow down the best type of local marine service provider to contact.

Yes. Ultrasonic antifouling systems are usually installed by marine electronics installers, full-service boatyards, or authorized dealers for the brand you choose. The work involves bonding ultrasonic transducers to the inside of the hull with epoxy, routing cables, and connecting the controller to the boat's DC electrical system. It's not typically a dive service or bottom-paint specialist job alone.

Since you're in the Keansburg, NJ area, these are good places to start:

• Seaboard Marine (Keyport) — Full-service repair facility with electrical and installation capabilities. Worth asking whether they install ultrasonic antifouling or will install a customer-supplied system.
• BoatPro Marine Service (Keyport) — Marine repair shop that can likely handle the electrical and hull-side installation if they don't already sell a system.
• Dockter Sea Marine Services (Highlands) — Mobile marine service with electronics and mechanical installation experience, making them a good candidate for this type of retrofit.
• Lockwood Boat Works (South Amboy) — Full-service yard that may be able to install an ultrasonic system during other maintenance.

If you'd rather work through an authorized dealer, several manufacturers maintain installer networks:

• urlBPS Marine dealer locatorturn0search3
• urlUltraSonic Antifouling dealer networkturn0search0

One thing to keep in mind: ultrasonic systems generally work best as a supplement to a good antifouling paint, not a replacement. They are most effective at slowing new algae and barnacle attachment and can extend the life of fresh bottom paint, but they won't remove heavy existing growth. Performance also depends on hull material, hull thickness, and proper transducer placement.

If you tell me:

• your boat length,
• hull material (fiberglass, aluminum, steel, etc.),
• whether it's kept in a slip year-round or trailered,

I can suggest how many transducers you'd likely need and whether an ultrasonic system is likely to be cost-effective for your situation.
