The Italian Classification Society, RINA S.p.A., is developing a new set of Rules regarding comfort conditions on board large motor-yachts. Relative to present owner requirements and technical enhancement, the new limit values will be more restrictive especially for yachts of more than 65 metres in length. In this respect designers and shipyards should consider structure borne noise and vibration level as leading parameters from the earliest design stages. In this paper some numerical tools, which allow prediction of noise propagation on board before sea trials to be carried out, are presented.

Abstract
The Italian Classification Society, RINA S.p.A., is developing a new set of Rules regarding comfort conditions on board large motor-yachts. Relative to present owner requirements and technical enhancement, the new limit values will be more restrictive especially for yachts of more than 65 metres in length. In this respect designers and shipyards should consider structure borne noise and vibration level as leading parameters from the earliest design stages. In this paper some numerical tools, which allow prediction of noise propagation on board before sea trials to be carried out, are presented.
