4'10" Chonk

4'10" Chonk

Dimensions: 4'10" x 19.5" x 2.5" (35 Litres)

The world's first surfboard with integrated magnetic shark deterrent technology. It not only helps keep you safer in the water but also features the same proven, top-selling 4'10" Chonk shape and construction.

Features

• Patented SHARKGUARD magnetic shark deterrent technology
• Includes 2 performance fins (performance fin box system)
• UV-resistant deck – no wax required
• Suitable for riders up to 80kg
• Rock-It Zebra Striped Sea Camo HDPE bottom slick

The Rock-It 4'10" Chonk with SHARKGUARD is a buoyant, easy-to-paddle, and maneuverable twin-fin softboard that floats like a butterfly and stings like a bee. It's the perfect board for young groms learning to surf and is equally suited for standing waves, river waves, surfing behind boats, and more.

SHARKGUARD

Six epoxy-coated specialized magnets are embedded into the foam beneath the HDPE slick bottom, projecting a magnetic field into the water around the rider. This magnetic field overwhelms a shark's electroreceptor sensory system, causing discomfort and encouraging it to move away without causing harm.

• No batteries required
• No charging required
• Maintenance-free technology

Sea Camo Zebra Striped Bottom

Along with the patented SHARKGUARD technology, this board features a Zebra Striped Sea Camo HDPE bottom as a visual shark deterrent. Research by a University of Western Australia neurobiologist indicated that zebra striping may reduce a shark's ability to identify potential prey by mimicking non-food sources in its environment.

Construction

Built with two marine-grade wooden stringers coated in an epoxy nano-coating to resist water absorption, the board is surrounded by proprietary EPS foam and finished with a UV-resistant, colour-fast soft-top deck.

• Textured soft-top surface – wax not required (wax may improve grip)
• Heat-laminated construction
• No harmful dyes, glues, resins, or toxins used during manufacturing
• Produced in a facility that utilizes collected rainwater
• Made using recyclable materials
• Backed by a 1-year warranty against manufacturing defects

Important Disclaimer

SHARKGUARD is designed to reduce the risk of unwanted shark interactions but does not guarantee complete protection or eliminate the possibility of shark encounters. Performance may vary between shark species, and ambush attacks from large predatory sharks may not be deterred.

Magnetic Field & Medical Devices

Because SHARKGUARD uses strong magnets, individuals with pacemakers, defibrillators, or other implanted medical devices should consult their doctor before handling or riding a SHARKGUARD-equipped board.

Strong magnets may also interfere with sensitive electronic devices such as hard drives, credit cards, and mobile phones. Keep electronics at least 12 inches (30 cm) away from the board.

Care Tip

When not in use, keep your soft-top surfboard out of direct sunlight to help preserve its appearance and performance.
