SBS Trailers are unveiling electric boat launcher at Seawork
SBS Trailers will bring Tectrax’s C-ROVR electric boat launch system to Seawork 2026, offering remote-controlled launching without a tow vehicle.


The Sialia Yachts 57 Deep Silence is the world’s most advanced fully electric luxury yacht created without compromises on performance, range, and comfort. It has an advanced proprietary drivetrain with a 256 kWh battery (upgradable up to 1MWh) and twin 400kW electric motors, delivering a cruising speed of 16 knots and a top speed of over 25 knots.


Its carbon fiber 16-foot (4.8m) hull is optimized by Vripack and it ensures a stable and smooth ride. The yacht can carry up to 12 passengers, offering versatile spaces for entertainment and relaxation.
Key features include a spacious climate-controlled cockpit, multiple lounge areas, a wide beach club with folding sides, and a garage for an 11-foot (3.3m) tender, while fast-charging capabilities ensure minimal downtime. This is the perfect yacht for journeys like Florida to the Bahamas, setting a new standard for full-electric yachts. Also, it has a biofuel-compatible range extender that expands its capabilities and increases safety level.
The entire design and production methodology has been developed with lifecycle in mind, from the carbon hulls – which are inherently longer lasting and more recyclable than GRP – to the choice of materials used in the finish.


There’s also the reduced maintenance aspect that makes electric motors so appealing – rather than the regular servicing schedule and the various fluids that need to be changed on a combustion engine, the electric motors on Sialia’s yachts need nothing more than a change of grease at 10 years.


The batteries are rated to 30,000 cycles and are guaranteed for five years along with the rest of the propulsion system, and all those aspects have been future-proofed by being upgradeable as technology advances, which in turn means less capital depreciation of your yacht over the coming years.
