How to Prevent Biofouling?

To stop biofouling, use ultrasonic antifouling systems that do not contain biocides. These environmentally friendly marine systems permanently prevent hull fouling. They protect nature and do not harm marine life. Their energy-efficient structure offers a clear advantage over traditional antifouling alternatives.

Eco-Friendly Method to Prevent Biofouling

Our seas can no longer handle traditional cleaning methods. Today, we need long-term solutions that not only clean but also protect the environment. Non-biocidal ultrasonic systems protect both marine life and the hull of your boat. By preventing biofilm formation, they also cut down your yearly boat maintenance costs.

How Does Marisonia Work?

Marisonia employs an ultrasonic antifouling system integrated into the boat’s hull. Using just ~6W of low energy, the device sends continuous vibrations. These vibrations prevent organisms that start biofilm formation from attaching to surfaces.

What Is Biofouling and Why Does It Occur?

Biofouling is the accumulation of algae, shellfish, and microorganisms on surfaces of marine vessels in contact with water. Water temperature, periods of inactivity, and surface texture all speed up this process.

Damage Biofouling Causes to Yachts

Biofouling doesn’t just harm appearances. The accumulation directly affects everything from driving experience to fuel consumption.

  • Increased drag
  • Up to 30% higher fuel usage
  • Reduced engine performance
  • Hull wear and tear
  • Less enjoyable riding
  • Traditional Antifouling Methods

    Traditional antifouling methods have been used for years but cause long-term environmental harm. They are also costly. The most well-known antifouling paints contain biocides, which are chemicals that severely threaten the marine ecosystem and the future of humanity.

    Using Toxic Paints

  • Toxic to all marine life
  • Needs annual reapplication
  • Costly in labor and time
  • Damages the gelcoat surface
  • Ultrasonic Cleaning with Marisonia

    Unlike traditional methods, Marisonia does not harm the environment or your boat.

  • Contains no biocides
  • No chemical emissions
  • Does not damage the hull
  • Quick return on investment
  • Best Ways to Prevent Biofouling

    The most effective way to prevent biofouling is to trust in technology. Working with technology secures our future. Ultrasonic technology completely prevents biofouling and offers a long-lasting, effective solution.

    Use Biocide-Free Systems

    Marisonia enables eco-friendly boat maintenance. By stopping biofilm formation, it prevents biofouling before it begins.

    Opt for Energy-Efficient Systems

    With very low energy use, Marisonia cuts down on costs. In the long run, it is much more profitable than traditional solutions.

    Preferring Plug-and-Play Solutions

    Painting every year and constantly cleaning off biofouling is labor-intensive. Annual re-painting also makes your yacht unusable for periods and pollutes the water where you swim.

    Choosing a system that requires only a one-time installation eliminates yearly maintenance hassles.

    How Often Should Biofouling Cleaning Be Done?

    Biofouling cleaning frequency depends on your method. With ultrasonic solutions, cleaning is unnecessary. With toxic antifouling paints, you need maintenance 1-2 times a year.

    How to Reduce Cleaning Frequency

  • Choose ultrasonic methods
  • If using traditional methods, select high-quality materials
  • If using paint, let it fully cure before launching
  • What Can Replace Antifouling Paint?

    Though antifouling paints have been the primary method for years, their environmental and economic impact means alternatives are gaining ground.

    New-generation solutions, especially biocide-free ultrasonic technologies, offer a permanent, sustainable answer.

    Biocide-free antifouling systems:

  • Work without chemical emissions
  • Do not harm marine life, coral, or plankton
  • Are long-lasting
  • Work passively after setup to prevent biofilm
  • Ultrasonic Systems vs. Toxic Paint—Which Should I Choose?

  • Includes haul-out, labor, etc.
