2008 ABEKING & RASMUSSEN

NURJA is one of very few SWATH (Small Waterplane Area Twin Hull) superyachts in existence. The SWATH design provides exceptional stability and seakeeping compared to conventional monohull or catamaran yachts of equivalent size.

Twin Strut Configuration:
The twin-strut arrangement reduces noise created by wave action between the hulls by giving disturbed water an escape path — a significant advantage over conventional catamaran forms.

Stability:
There is no real limit to wave height for operability — wave height and period between peaks are factors for comfort, not safety. Unlike catamarans, a SWATH vessel does not suffer the "hull spreading" effect in heavy seas due to the displacement aspect of the hulls. Damage stability rated to two flooded compartments — vessel remains afloat and stable even with water at main deck level.

Roll/Pitch Control:
Marine Dynamics Inc. active control system integrated with the Böning AMCS (see Ship Automation section). Achieves comparable results for roll as for pitch trimming. System recommissioned during refit. Four fin stabilizers provide active stabilization at anchor and underway.

Pressure Sensor System:
Monitors hull pressure differential — critical for SWATH trim capability. Integrated into the Böning distributed processing network.

Trim Tab System:
Trim tabs on rudders increase rudder efficiency and reduce turbulence effects — a SWATH-specific feature.

Noise & Vibration:
No unnatural noise underway — the SWATH platform delivers the quiet, stable ride the design promises.

Main Engines:
2 x Caterpillar C32 ACERT Diesel (820 kW / 1,100 hp each) at 2,100 RPM
