NURJA - ABEKING & RASMUSSEN FOR SALE

NURJA ranks among the rare SWATH (Small Waterplane Area Twin Hull) luxury superyachts afloat. This advanced SWATH platform delivers remarkable steadiness and comfort versus typical monohull or catamaran motor yachts of similar dimensions.

SWATH technology

NURJA is one of very few SWATH (Small Waterplane Area Twin Hull) superyachts in existence, her advanced geometry delivering exceptional stability and seakeeping compared to conventional monohulls or catamarans of equivalent size. Its twin-strut configuration reduces noise created by wave action between the hulls by giving disturbed water an escape path, a significant advantage over conventional catamaran forms. There is effectively no limit to wave height for operability; wave height and the period between peaks influence comfort rather than safety. Unlike catamarans, a SWATH vessel does not suffer the “hull spreading” effect in heavy seas due to the displacement aspect of the hulls, and damage stability is rated to two flooded compartments, with the vessel remaining afloat and stable even with water at main deck level. A Marine Dynamics Inc. active control system is integrated with the Böning AMCS (see Ship Automation section) and achieves comparable results for roll as for pitch trimming, and the system was recommissioned during the refit. Four fin stabilizers provide active stabilization at anchor and underway. A dedicated pressure sensor system monitors hull pressure differential—critical for SWATH trim capability—and is fully integrated into the Böning distributed processing network. Trim tabs on the rudders increase rudder efficiency and reduce turbulence effects, a SWATH-specific feature. Underway there is no unnatural noise; the SWATH platform delivers the quiet, stable ride the design promises.

Propulsion & steering

Power comes from two Caterpillar C32 ACERT diesel engines, each delivering 820 kW (1,100 hp) at 2,100 RPM. Between 2021 and 2024 the mains benefitted from a comprehensive overhaul that included a crankshaft overhaul, new turbochargers, injector replacement, and cylinder head inspection, and they were FAT tested in December 2022 for verified performance. Propulsion is via a twin-screw configuration on two shafts, turning G‑NiAlBz (nickel‑aluminium‑bronze) propellers of 1,750 mm diameter with a 1.32 m pitch, with propeller shaft spare parts sourced during the refit to ensure long-term serviceability.

Power is transmitted through two ZF 3310 gearboxes that were fully serviced during the refit with complete disassembly, reconditioning, and reassembly. Their Vulkan couplings with Vulkardan E elements underwent a complete overhaul with new disc flanges, diaphragms, and all fasteners, while new Vulkan engine couplings and vibration dampers were installed on the main engines to further refine smoothness and reduce vibration throughout the drivetrain.

Directional control is equally robust, with rudder blades and shafts removed during the refit for inspection, polishing, and precise reinstallation. Trim tabs on the rudders enhance efficiency as a SWATH‑specific feature noted under SWATH hull technology. The hydraulic steering system was overhauled during the refit, including full pump and valve service, and precise low‑speed maneuvering is assured by an Aburas 13 bow thruster, model STT‑102033, rated at 104 kW.
