To Protect The Peace & People


In 1986, when we founded our shipyard to design and build fast boats in advanced composites, our dream was to become a world leader in our field. The indications were not favorable that such an ambitious undertaking would succeed. But the few hand-made boats that we created with such pride and pleasure left us free to build boats just the way we wanted them. Today, we are happy to see that we have customers who share our ideals. Today, Yonca-Onuk is an industrial-scale enterprise with a modern shipyard capable of serial production of state-of-the-art pleasure, commercial and naval craft. We are proud that, with a highly specialized dedicated workforce capable of creating our own concepts, developing our own technology and building to perfection, Yonca-Onuk is now a technology leader, a standard setter, just as we dreamed in 1986.

Our struggle continues in research and development of new technologies, in order to hold the leading position won by imaginative application of our skills and technical resources. This will ensure that, now and in the future, we will continue to fulfill our customer's requirements and keep our commitments. Yours sincerely
