What makes this yacht different than all others in this range?

1 Her High Speed Cruising Hull will not only be approximately 30% faster than “normal” displacement yachts with similar power, but will also reduce fuel consumption at long range speed and has proven to be extremely comfortable.

2 The ground breaking use of Ride Control, which is a combination of roll reduction and pitch reduction, will greatly improve comfort when cruising at 20 knots
Times have changed and instead of focusing on outright speed, ‪Spectre‬ is the first monohull superyacht to be fitted with a Ride Control System (RCS) by Naiad Dynamics to improve both comfort and performance. “The trend today is towards displacement yachts with lower speeds, longer range and more comfort,” says naval architect Frank Mulder. “But the owner still wanted something that was faster than your average yacht and Spectre can cruise at 20 knots with a top speed of 21 knots.

With the initial data from Naiad’s simulations, Mulder Design fine-tuned the hull design and carried out 25 different CFD analyses before final tank testing. “The initial hull form was already very efficient, but each new CFD analysis resulted in incremental gains,” says Mulder. “That’s the beauty of CFD. We can arrive at a point after which we don’t see any improvements, and the tank tests are really just to confirm the CFD results.”
In addition to improving motion comfort, Spectre’s hull form and appendages provide a virtuous circle of efficiency benefits. Less drag means more speed, lower fuel consumption and longer range (well over 6,000nm at 12 knots) for the same installed power. Less fuel burned also means smaller tanks (just 127,000 litres), and thus less weight to carry around.
Spectre is powered by twin 2,580kW engines, the smallest in MTU’s 4000 series, but her top speed is at least 25% faster than a conventional displacement monohull. When Mulder was on board Spectre with the owner during final sea trials prior to delivery, he noted that at 15 knots the engines were running at less than one-third power.
