New for 2022, the Hull Shield HD1 ultrasonic antifouling system offers complete, versatile, and reliable antifouling protection.

The HD1 is a single transducer unit that can be installed to protect hulls, drives, rudders, stabilizers, and more. This single transducer system can be combined with other systems to provide broad protection for vessels of any size. The HD1 facilitates an easier installation process compared to larger controllers when installing a transducer in an area where routing signal cables back to a larger central controller is impractical.

Maintaining a clean hull 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 – using Hull Shield stops this destructive routine cycle. You will enjoy significantly less maintenance costs, haul-outs, and extended paint life – all while having confidence that your boat will be operating at peak performance and efficiency.

HD Series

As part of the new HD series, the HD1 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.

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.

HD1 Controller Module

The compact HD1 controller is designed to be a low-power device that can be easily installed inline with a single transducer. HD1 controllers generate the ultrasonic signals which power the transducer and consume about 0.25Ah 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.

HD series controllers operate on 12VDC battery systems.  If your boat is 24VDC a 24V to 12V converter will be needed, and can be purchased here.

Single Ultrasonic Emitter

This system is equipped with one transducer emitter used to generate the ultrasonic signals which disrupt marine fouling.

Solar / Wind / Low-Power Mode

The HD1 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).

DRIVES & RUNNING GEAR –  one transducer can provide dedicated protection for any single isolated part. Examples of isolated parts are drive shaft & props, rudders, exterior engine brackets, struts, swim platforms, and trim tabs. Because these parts are isolated from the hull and each other, a transducer is required for each isolated part.

The HD1 Package Includes:

• 1x Hull Shield HD1 Control Module with Integrated Power Cable and 5ft of integrated Signal Cable
• 1x Submersible Ultrasonic Transducers with 15ft of Cable
• 1x Epoxy Kit
• 1x Printed Installation and Operation Manual

Easy Installation

Hull Shield systems are simple in function and installation. Systems can be installed in a single day and require no technical skills. Besides the simple tools most customers have, everything required for an installation is included in with our products.

The Hull Shield controllers are best mounted in an accessible compartment. The transducers are simply attached directly to the surface of the hull or drive with the supplied 2-part epoxy.

Hull Shield transducers are waterproof and submersible. Transducers can be attached to the inside surface of the bilge, or externally on the transom.

Lifetime Warranty

All Hull Shield Ultrasonic products are fully covered under a Lifetime Warranty for the original purchaser. The warranty protects against defects in materials, workmanship, and parts issues.

Please Note: Hull Shield HD1 ultrasonic antifouling kits are provided with a transducer having 15ft of attached signal cable. Depending on boat size and installation location, you may require additional signal cable to span the distance between the transducer mounting location and the HD1 controller. Extra signal cables can be added to your order by clicking HERE. Alternatively, the power cable for the HD1 can be extended with 14-16 AWG so that it can be placed nearer the transducer (see installation instructions for gauge and length limitations).

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