Noise and Vibration Control is an important topic on board nowadays new build Yachts. Not only Mega Yachts but also series build motor and sailing Yachts.

In order to achieve Comfort Class 1 noise and vibration levels we need to enter in a very early stage of the project (Design Stage). At this stage we are able to assist you and look into what can be achieved onboard your Yacht. Normally a consultant is hired by the Yard after the contract is signed which is “too late”.

Nowadays (guaranteed by Silent Line) we are able to achieve noise levels below 35 dB(A) at anchor condition and noise levels below 45 dB(A) at transit condition on board Luxury Yachts starting from 30 meters and up.
