Couach has delivered the 163-foot Belongers, which is Hull No. 2 in the 5000 Fly series and includes new technology called SilentCab and VRS.

Her owner pushed the yard to revisit the 5000 Fly’s design in terms of noise reduction and vibration both at anchor and underway. The Couach team worked with Van Cappellen Consultancy, an acoustics firm, to create a suspension system called SilentCab that isolates the cabins away from the sources of vibration. VRS (which stands for Vibration Reduction System) further enhances onboard comfort by acting as an interface that either prevents or corrects vibrations from different sources.

The result is that Belongers has a 42 dB(A) decibel reading at 12 knots — lower than what drivers experience in luxury sedans on the road. For more perspective, 65 dB(A) is the level of normal conversation. At anchor, the decibel reading drops to 35 dB(A), which is comparable to wind rustling through trees, according to Couach.

Belongers has a top speed of 28.3 knots. At a cruising speed of 12 knots, her range is 2,200 nautical miles.

Twelve guests are accommodated in six staterooms, and there are quarters on board for 10 crew.
