Six years after the launch of the wooden Sirocco, Mr B.E. Ruys ordered a new motor yacht in early 1965, this time made of steel. The name became Sirocco again, but the client did not want the addition II to be added. The length was 25.85-metres, almost the same as the previously built wooden yacht. The name of the yacht’s designer was, however, new: Willem de Vries Lentsch Jr. As a family member of the De Vries Lentsch shipyard Het Fort, Willem was no stranger to the De Vries brothers. After all, both shipyards were among the founders of Feadship in 1949.
