Description

Enjoy 24/7 antifouling protection with a Hull Shield HD2 antifouling system. Ultrasonic antifouling uses the power of ultrasound to keep your hull and running gear clean and free of marine fouling. Our systems offer a fully automatic solution that works around-the-clock to keep your boat clean so that you don’t have to.

Hull Shield technology has proven itself over and over again with years of reliable service to boaters the world over. Our products are the preferred choice for boaters wanting the absolute best antifouling solution available.

Maintaining a clean hull can dramatically increases performance, speed, and fuel efficiency. Keeping your hull clean with ultrasound also extends the life of your bottom paint. Layers of valuable paint are removed every time the hull is scrubbed or power-washed. Hull Shield can help end this routine and destructive cycle. You will enjoy less maintenance costs and fouling related haul-outs while also extending the life of your bottom paint. With Hull Shield, you can be confident that your boat is operating at peak performance and efficiency.

HD Series

As part of the new HD series, the HD2 provides antifouling protection for hulls, drives, and other parts of a vessel that are prone to marine fouling. The HD series offers an increased efficiency profile that is capable of delivering nearly double the power directly to the transducers when compared to prior versions. Additionally, all HD series products feature our latest hardware technology that boosts overall effectiveness by utilizing a higher frequency bandwidth. HD series products also provide more than twice as many frequencies and ultrasound bursts in targeted ranges.

The HD2 is a dual transducer unit that can be installed to protect hulls, drives, rudders, stabilizers, and more. This ultrasonic antifouling system can be combined with other systems to provide broad protection for vessels of any size.

Drives, Rudders, & More

Not just for hulls – Hull Shield can protect your drives and running gear too! Drives are isolated from the hull by motor mounts, gaskets, seals and other insulative materials that block ultrasound from passing to shafts, props, and rudders. Because of this, the drive system requires dedicated transducers to gain the most benefit from ultrasonic anti-fouling. Inboards, pods, sterndrives, and sail-drives can all be fitted with a transducer to enable full anti-fouling protection. Rudders are isolated from the hull in the same way as the drives and also require a dedicated transducer.

Hull Shield Antifouling Technology

Ultrasonic antifouling works by using sound waves to physically repel fouling organisms away from the surface before they can permanently attach. As a bonus, the higher frequency band of ultrasound also disrupts the reproductive cycles of certain types of bio-fouling.

Hull Shield systems operate similar to a stereo and speakers. The controller sends ultrasound signals to transducers attached to the hull or running gear, the transducers receive the high-frequency signals, transforming them into ultrasonic pulses.

Each pulse creates a microscopic shockwave that runs across the hull and drive gear. These ultrasonic waves work to ablate, loosen, and repel fouling which is contacting the hull and drive surfaces. When used in conjunction with an ablative bottom paint, Hull Shield systems are the most effective and long-term antifouling solution available.

HD2 Controller Module

The compact HD2 controller is designed to be a low-power device that can be easily installed. HD2 controllers generate the ultrasonic signals for two transducers. The controller consumes an average of 0.5Ah of current at maximum potential (when the battery system voltage is at or above 12.7V). The controller is to be mounted in an accessible location near a sufficient 12V battery system supply. The transducer signal cables are routed back to the controller. The HD2 enclosure is IP68 and NEMA rated for waterproof installation, and all connections are IP67 rated or above.

HD series controllers operate on 12VDC battery systems. Please contact us for alternate options for 24VDC systems.

Ultrasonic Emitters

This system is equipped with two transducer emitters whichgenerate the ultrasonic signals which disrupt marine fouling.

Solar / Wind / Low-Power Mode

The HD2 controller is designed for optimum efficiency and ultrasound power delivery. The system is engineered to provide stable operation, even when powered from solar and wind supported power systems with fluctuating battery cycles. The controller will actively adjust the output power to match the current charge-state of the battery system – conserving power when necessary to preserve battery power and extend the length of time the system can operate.

The controller actively monitors system voltage levels which allows it to automatically enter  power conservation mode (PCM) when the system batteries are not being maintained. PCM is a completely automated process which reduces the average system power consumption to as low as 5 watts depending on available battery power.

Coverage

HULLS – each transducer provides approximately 200sqft of protected underwater surface area. A rough estimate of your underwater surface area can be calculated by doubling your draft, adding it to your beam, then multiplying by your LWL (length at water line).

This unit can also be combined with other Hull Shield systems to extend protective range and/or antifouling intensity.
