Blade Runner: Sword of the Sea

Introducing the Glider Yachts' XD18.

The Glider’s power plants will be located within the hull blades.
GILT-EDGE DESIGN The Glider’s efficient ride comes from a combination of its hull form’s hydrodynamics, water-jet propulsion, a Zero Drag Steerage System and a proprietary Stability Control System. This design requires less power than same-size monohulls, according to the builder. A 60-footer is powered by four 300-horsepower Rotax engines (the same engine used in Sea-Doo personal watercraft) for a 30-knot cruise and a 70-knot top end.
Q&A: ROBERT MCCALL, FOUNDER Q: What inspired you to create Glider Yachts? A: My engineering background and lifelong love of sailing had me hooked on design from a very young age. I've also been a longtime fan of Nigel Irens, who designs fast multihull racing boats. Q: Besides the hull, where else does the Glider dif er from traditional yacht design? A: Gliders are far more advanced in the aerodynamics of the superstructure. Our boats have a considerable windage reduction compared with a traditional motoryacht, with its flat surface area along the hull. We've also integrated all navigation and communications equipment within the structure.

In 2007, Capt. Robert McCall was piloting a wave-piercing catamaran ferry on a tricky run. Waves were in tight rows, battering the smaller monohulls around his ferry.

“During that trip, I became acutely aware of the boat’s capabilities and limitations,” says McCall. “I realized that its exceptional seakeeping abilities could be taken much farther with modern technology and hydrodynamic advances.”

McCall spent months designing his Wave Dominator hull form. Now, after eight years and thousands of hours of design, structural analysis, computational fluid dynamics and wind-tunnel testing, he is ready to build his Glider XD18.

This 60-footer has an over-the-water cockpit and slender twin hulls (called blades). They were engineered with processes like those used in advanced aerospace design and have a multidimensional form.

Their functions should include faster speeds, improved fuel efficiency and a soft ride in rough seas. McCall says his SX-Eand GT models, which range in size from 98 to 230 feet, will offer 50 percent faster speeds and 60 percent better fuel efficiency than conventional sport yachts and superyachts in the same size range.

“Gliders have sharp and streamlined hulls with a high power-to-weight ratio, giving them a reduced power requirement to achieve the same speeds, or much faster speeds, with the same power,” he says.
