Yacht Building Management (YBM) is a custom superyacht builder focusing on new construction and refit of luxury sailing and motor yachts.


Based in Gdansk, Poland, YBM was established in 1991 by sailing enthusiast Janusz Zawadowicz to build large, contemporary sailing and power yachts. Each luxury yacht launched by the shipyard, ranging from 10 to 37 metres in length, has been unique and built to owner specifications, which highlights the company’s versatility and its knowledge of all facets of yacht construction.

Notable Yachts

YBM’s luxury sailing yacht launches have included the 36.3-metre sailing superyacht White Eagle (now called Alexa of London), delivered in 1991. Rigged as a gaff cutter, she features classic exterior styling by Yacht Studio Strawinski and interior design by Jeorg Koehneke. Yacht Studio Strawinski also designed Green Magic, a 25.5-metre luxury sloop built by YBM in 1999.

YBM’s power boat portfolio includes Anna, an 18.35-metre cruising motor yacht converted from a traditional Dutch boat, and Katama, a 19.85-metre luxury motor yacht designed by Newcruise and delivered in 2001.


YBM prides itself on using superior construction techniques and materials, as well as its ability to translate customer desires into one-of-kind designs. In addition to luxury yacht construction and refit work, as its name implies, YBM offers management services for new yacht building projects.
