Silversea Cruises President and CEO Roberto Martinoli has elevated the brand into one of the industry’s leading ultra-luxury cruise lines. On Jan. 1, Martinoli assumed the role of senior advisor to Royal Caribbean Group President and CEO Jason Liberty. Barbara Muckermann, previously chief commercial officer, became Silversea’s president and CEO and joined Royal Caribbean Group’s executive committee, according to a company press release.

Muckermann becomes the second woman to lead one of Royal Caribbean Group’s three wholly-owned brands, and joins Celebrity Cruises President and CEO Lisa Lutoff-Perlo, and Royal Caribbean International President and CEO Michael Bayley. She will oversee all of Silversea’s employees and crew, and will report to Jason Liberty.

Muckermann brings more than 25 years of experience in the travel and hospitality industry, with an emphasis on creating exclusive high-end vacations. She first joined Silversea Cruises in 2001, and held several roles at other luxury and cruise brands from 2005 to 2016 before returning. In her post as Silversea’s chief commercial officer, Muckermann oversaw all aspects of sales, marketing, revenue management and guest relations, as well as strategic communications and brand and product strategy. Muckermann is a Doctor in Political Sciences and Economics, and holds a joint MBA from London Business School and Columbia University.

“This is an exciting moment for Silversea as we continue to add new ships and return to the Asia market,” Muckermann said in the release. “I’m thrilled to build on our achievements under Roberto and focus on growth in the years ahead.”
