The REICHEL/PUGH-NAUTA 47m SUPERYACHT Nilaya, Royal Huisman’s Project 405

Reichel/Pugh’s Design #283, the 47m Nilaya was R/P’s first and very welcome opportunity to work with Royal Huisman whose passion for perfection matches Reichel/Pugh’s.

Reichel/Pugh-Nauta 47m NILAYA’s design development is a result of Reichel/Pugh’s 40 years of yacht design experience while leveraging the latest CFD hydro technologies to advance performance superyacht design.

Earlier Superyacht designs by Reichel/Pugh are groundbreaking and include the iconic yachts, the 147’ Visione, the R/P-Nauta 112’ Nilaya, the 200’ ketch Hetairos, the R/P-Nauta 130’ My Song and the 100’ Magic Carpet and Galateia. Visione 147’, Nilaya 112’ and Hetairos have each won overall the Superyacht Regatta the St Barts Bucket.

In developing the Nilaya design Reichel/Pugh undertook an extensive CFD seakeeping study. The goal was to improve the seakeeping and motion of the Nilaya, while motoring upright and at various speeds and angles of heel in different waves conditions. Designed by John Reichel and involving CFD scientists Georgio Provinciali/Michel Kermarac, and Caponetto-Hueber on the hydro modelling side, R/P used 10 years of historical wave data from the Eastern Caribbean and Greece ultimately testing 12 models before development of the final hull shape. This was a comprehensive study to not only improve seakeeping and handling, but also improve real performance and ORCsy rated performance. This study, as with our earlier ones, will advance the designs of our future superyachts.

Royal Huisman pioneered their comprehensive Featherlight™ hybrid (aluminum carbon composite) construction approach to this 47m state-of-the-art performance cruiser, with exterior and interior by Nauta Design. Continuous weight monitoring throughout construction confirmed the shipyard’s goal of achieving an 11% reduction of the weight of its typical advanced aluminum cruising yachts via this process. Most importantly, it has reduced weight without sacrificing stiffness or cutting corners on quality.

Reichel/Pugh Naval Architects, John Reichel, David Oliver and Tony Beale managed the project and daily communications between Royal Huisman, designer Nauta Design and the owner’s project manager Nigel Ingram of MCM Newport. Reichel/Pugh worked with Royal Huisman and Nigel Ingram daily throughout the design and build process jointly monitoring the weight and VCG study.



“Weight distribution is critical for assuring comfortable motion on a cruising yacht,” John Reichel said. “We gave the shipyard team a weight study early on, not just for the total but for balance and maintaining the proper center of gravity. Royal Huisman responded with extensive Excel sheets showing the weight of every element. That’s a process typical of the construction of a high-end racing yacht.”

“Royal Huisman used Finite Element Analysis (FEA) of Nilaya’s 3D model to engineer the structure to ‘a very high level,’” and according to Jim Pugh, “accurately predicting longitudinal stiffness, strength and VCG.”

“Bringing in the mast and sail designers early in the process has significant advantages,” explained Jim Pugh. “From the aero CFD side, Rondal and the sail designers shared high quality data about sail forces and sail loads that we integrated into the hydro CFD studies of the candidate hulls. This markedly improved the quality of the CFD hull testing and the resultant performance prediction. The mast and sail loads were then input into the hull and deck’s structural engineering,” said Pugh. “Such a study will yield remarkable results.”

The Reichel/Pugh-Nauta 47m NILAYA is also the first yacht of this size range designed to take advantage of the structured luff sail design pioneered by Doyle Sails, a choice that allowed the entire Rondal mast, rig, and components to be lighter — a key point considering her Panamax air draft. To take advantage of the very narrow headsail sheeting angles possible, Rondal created a radical new curved carbon fiber spreader design that is both shorter and more aerodynamic than anything previously available. Rondal also supplied new generation hybrid (carbon and aluminum) captive winches, hatches, and various sail handling gear. Most deck hardware is titanium.

Royal Huisman has delivered a luxurious global cruising yacht that will also be capable of podium finishes at superyacht regattas. Nilaya is expected to flex her innovations at the 2024 St Barts Bucket.
