Cay Electronics Showcases CayCube – Award-winning Alternative to Traditional Onboard Power, at Palm Beach 2026

March 24, 2026

After a successful pre-launch marked by the prestigious Newport Boat Show Innovation Award last fall, Cay Electronics will be showcasing the cutting-edge CayCube technology at Palm Beach International Boat Show from March 25 to 29.

CayCube is the culmination of 40 years of maritime experience resulting in a revolutionary alternative to standard generators on board.

This solid-state, silent running system provides today’s demanding boaters with the fume- free, fire-safe power needed to replicate home comforts — from air conditioning and freezers to microwaves, battery chargers and personal devices — without the noise, vibration or carbon emissions of a standard generator.

Other key features of CayCube are the absence of moving parts, and installation requiring no costly plumbing or exhaust fittings. The compact device is entirely maintenance-free and remarkably easy to install and integrate into your vessel.

CayCube provides for an extended runtime with 48 hours or more of support for air conditioning, appliances and essential equipment such as battery chargers or stabilizers.

Recharging options include shore power or generator. A hybrid option is available that adds a dedicated alternator to the propulsion motor for fast recharging and limitless runtime. For those seeking 100% sustainability on board with zero carbon emissions, it can be recharged using solar or wind power.

“We are thrilled to introduce CayCube to the market,” said Rufus Van Gruisen, president of Cay Electronics. “This product underscores our commitment to providing a sustainable, effective innovation to shipyards, installers and boaters alike, while setting a new standard in onboard comfort. “

Available in three high-performance models with peak power outputs of 9, 18, and 27 kW, CayCube offers the ultimate peace of mind for life on the water.

Visit us at Booth #305 in the Evernia tent at PBIBS 2026, in Downtown West Palm Beach from March 25 to 29 to see this new technology in person.
