Our Partner: De Antonio Yachts
SD Nautical is proud to be the home of De Antonio Yachts in Australia. Since 2012, this Barcelona-based shipyard has revolutionised the day-boat market with a unique concept: hidden outboard engines.
By concealing high-performance outboard engines underneath a sunpad or engine hatch, De Antonio Yachts offers the best of both worlds:
Low Maintenance & Performance:
The reliability and ease of outboard engines.
Clean Aesthetics:
The sleek lines and full-beam swim platforms typically reserved for inboard vessels.
Reduced Draft:
The ability to venture into shallow bays and beach closer than ever before.
From the flagship D50 Coupé to the revolutionary, 100% electric E23 Catamaran, our range is designed for those who refuse to compromise on style or functionality.
