New principles

Philippe Briand has unveiled the latest sailing yacht concept to come from his London- based design studio, the 90-metre SY300.

17 April 2019


With a traditional sailing rig, the 1,550-tonne ketch project SY300 has been created to outperform other sailing superyachts, while providing a head-turning aesthetic and comfort on board. The SY300 would best suit a passionate sailor who demands speed on the water as well as exceptional design and style.

Unlike the growing number of sailing superyachts that are effectively motor yachts with sails, requiring engines to assist in propelling them through the water, the SY300 has been developed with a similar design approach used in smaller, high-performance racing yachts. The design still includes the hallmarks of Philippe Briand’s award-winning design pedigree, including clean, dynamic lines and outstandingly efficient naval architecture.

Being fully wind-propelled, the SY300 would be a true leader in the new wave of green superyachts, in particular its hull-form characteristics and predicted performance. It’s hydrodynamic efficiency means more power could be harnessed through underwater turbines to charge the batteries on board. In the best conditions a maximum speed over 20 knots would be reached . Potentially If 50% of the energy is captured it will be the equivalent of that produced by a 500 kW generator, while maintaining a speed around 15 knots.


Briand chose a conventional two-masted sailing rig to complement the contemporary hull with its inverted bow, as this proves to be the most effective. With its foremast towering 95.3 metres above the waterline, the SY300’s upwind sail area is 3,560 square-metre, while its downwind sail area is 6,600 square-metre, including a 3,500 square-metre spinnaker.

The design of the carbon fibre masts and rigging is heavily informed by the experience Briand acquired during the development and construction of the landmark 67-metre S/Y Vertigo and 73-metre S/Y Sybaris. 

The yacht’s length at the waterline is 78 metres, with a maximum beam of 14 metres. Final interior layouts can be tailored to an owner’s desires, but initial drawings of the SY300 allow provision for a large full-beam owner’s suite with his-and-hers bathrooms, an office and a private terrace on the main deck. A vast, full-beam saloon leads forward to a dining room on the port side or a play room on the starboard side, and a second door to the owner’s office.

A further six guest suites are located on the lower deck, as well as accommodation for up to 17 crew. A full-beam gym on the lower deck has sliding doors and steps leading up to the aft deck pool, and the adjacent spa features a Jacuzzi and massage room.

“I am a purist at heart. Every Philippe Briand design is guided by the golden principles of balance, efficiency and performance on the water, from the single-handed ocean sailing boats that I raced to victory in my early career, to some of the world’s best-known sailing superyachts,” commented Philippe Briand.

“Staying true to our name, this SY 300 design showcases a yacht with purpose that is in keeping with the authentic spirit of sailing. I picture it being ideal for a passionate sailor who wants to stay in touch with the water and the power of the wind. They could even take the helm of the yacht themselves.”
