About Selene Yachts

Premium production

Long-range trawler and explorer-yacht builder founded by Howard Chen in 1998, building in its own yard at Zhuhai, China — Classic Explorer and Voyager trawlers from 12.7 metres, Ocean Explorers to 30 metres, the faster Artemis line and the 39-metre Selene 128.

Selene is a division of the Selene Yachts Group, founded in 1998. The name goes back to 1970, when the Taiwanese architect Da-Hong Wang designed a memorial to the Apollo 11 moon landing and called it Selene, after the Greek goddess of the moon; years later Howard Chen studied under him at the School of Architecture of Tunghai University and, learning of the memorial, gave the name to his new line of yachts. The first shipyard opened in Dongguan, China, in 1998 — the historic headquarters is still in Hou-Jie, a town known for high-end furniture whose woods, veneers, granite and skilled labour suited yacht interiors — and the first yacht reached the United States in 1999. Since 2006 the company has had its own stainless-steel workshop. In 2008 it opened a second yard at Zhuhai near Macau, which Howard Chen landscaped himself, with two workshops of about 150,000 square feet, a 32,000-square-foot warehouse and four 100-ton cranes. For years the smaller yachts were built in Dongguan and the larger in Zhuhai; in 2017 the molds and tooling were moved, and from 2018 all boats are built at Zhuhai, which the company says can produce up to a hundred yachts a year. Over some twenty years Selene has built almost 400 yachts from 38 to 103 feet.
