HIGH-SPEED PERFORMANCE WITH MAXIMIZED ONBOARD SPACE
The Extra X99 Fast was developed to meet demand for a high-performance yacht that does not compromise on comfort or usable space. The vessel is optimized for fast coastal cruising.
The project required a propulsion solution capable of delivering high top speeds, smooth cruising performance and shallow-water accessibility. At the same time, the yacht needed to maintain a spacious layout and strong connection between interior and exterior living areas.
DUAL MJP 550 DRB WATERJETS FOR SPEED AND CONTROLPACE
Marine Jet Power supplied dual MJP 550 DRB waterjets for the X99 Fast, providing a propulsion solution that balances high-speed performance with precision handling. The DRB system is engineered to deliver responsive control, strong thrust and reduced onboard noise.
Key advantages of the propulsion system include:
• High-speed capability up to 37 knots in standard configuration
• Precise maneuverability for docking and coastal navigation
• Reduced vibration and improved onboard comfort
• Shallow draft operation for accessing coastal and island destinations
• Reliable performance in high-speed planing applications
The integration of waterjets with twin MAN engines ensures efficient power delivery and smooth performance across the vessel’s operating range.
FAST, VERSATILE AND DESIGNED FOR MODERN YACHTING
The Extra X99 Fast delivers a unique combination of performance and lifestyle:
• Top speeds up to 44 knots with optional triple drive configuration
• Shallow draft enabling access to beaches and shallow anchorages
• Large aft social areas with approximately 75 square meters of usable space
• Lightweight construction improving efficiency and acceleration
• Seamless indoor-outdoor living with open design concept
WHY MJP 550 DRB
MJP 550 DRB waterjets deliver a balanced combination of speed, control and comfort, making them ideal for high-performance yachts. The mixed-flow design provides strong thrust and smooth acceleration, while the double reversing bucket system ensures precise maneuverability during docking and low-speed operation. With inboard hydraulics and a robust duplex stainless steel construction, the 550 DRB offers reliable performance and reduced onboard noise. Learn more about the MJP DRB waterjet series.
