HDY
FOR YACHTS
Stop the fouling, lower your costs, and save time, all while increasing efficiency and performance.

HULL SHIELD™ HDY systems can protect hulls, props, shafts, jet-drives, pods, steerage, control gear, sea chests, box coolers, & pipework. Yacht owners and operators will experience the benefits of reduced fuel consumption, lower emissions, improved performance, more responsive and safer handling, extended service intervals, and increased asset lifespan.
HULL SHIELD™ HDY Series is the world’s premier ultrasonic antifouling solution, engineered to prevent bio-fouling on yachts and large vessels in even the harshest marine environments. Backed by years of collaboration with maritime experts, the HDY Series delivers a powerful, eco-friendly alternative to traditional antifouling methods. By eliminating toxic chemicals and minimizing drydocking and maintenance, HULL SHIELD™ ensures your vessel operates at peak efficiency with reduced environmental impact. Experience sustainable, high-performance protection for hulls, running gear, and critical components with HULL SHIELD™ HDY Series.
HDY antifouling products work 24/7 to continuously target and prevent biofouling from developing on surfaces that you need protected from fouling.

PROTECTING YOUR ASSETS
Yacht owners and operators understand that reducing maintenance and downtime are critical when money is on the line. Hull Shield products help protect your assets inside and out. HDY ultrasonic antifouling systems will add an additional layer of valuable protection while providing a more sustainable and ecological long-term solution.
Hulls
Hulls can be fitted with a distributed array of ultrasonic transducers. Hull Shield transducers will function together to provide complete coverage of the submerged structure.
Shafts & Props
Bio-fouling accumulation on shafts and props can be detrimental to fuel efficiency. Hull Shield can deliver ultrasound directly into the prop via the shaft, adding protection to both simultaneously.
Pod-Drives
When pods become fouled, both thrust and steerage are affected. Fouling leads to poor fuel efficiency and reduced handling response. Z-Drive and L-Drive pods can be targeted directly with Hull Shield ultrasonic antifouling.
Jet-Drives
Performance and efficiency can suffer significantly from fouling inside the drive. Fouling remediation can be complicated and increase downtime. Hull Shield can target jet-drives to reduce fouling and maintenance.
Steering & Control Gear
Hull Shield ultrasound can be used to target steering, stabilizing, and other control surfaces. Reducing fouling on these surfaces increases hydrodynamic efficiency and results in more responsive and safer handling of the vessel.
Sea Chests & Box Coolers
Invasive biofouling in sea chests and box coolers reduces cooling capacity and increases maintenance downtime. If left uncheck, fouling within the cooling system can lead to equipment failure. Ultrasonic antifouling can be easily deployed to protect these areas using non-intrusive installation methods.
Pipework & Valves
Biofouling can affect the flow rate and function of various types of pipework. Targeted ultrasound treatment is effective at reducing fouling in pipes and decreasing subsequent maintenance intervals and downtime.
