Xenon
Xenon (ex-Corona / Hawaii VI / Stormsvala)
A 1913 Johan Anker Yawl—Awaiting a Faithful Revival
Xenon is believed to be the 1913 Johan Anker design Corona, built at Anker & Jensen in Vollen, Norway (builder’s No. 132) for ship-owner William Wilhelmsen. Classified Bureau Veritas A1 and originally carrying sail number D6, she appears in the KNS yearbook (1913) as a 12.5-Sailmetre yawl—the “D” prefix denoting a rating larger than the 12mR “E.” Historical notes indicate she later sailed as a 12mR after the mizzen was removed. A sistership, Athene (delivered in 1914 to the Wilhelmsen family), has been lost to history; Corona survived under new names and owners and now rests in Italy requiring a complete reconstruction.
Construction & Present Condition
Original mahogany planking on alternating steel and oak frames; steel ballast. The vessel is dismantled/stripped and in urgent need of a total rebuild: new planking, deck, and spar(s), with the internal structure to be evaluated. The hull has retained its shape and is not deformed, offering a viable basis for a historically correct restoration.
Equipment: not to be considered (present items incomplete/obsolete).
Status: SMANTELLATA – DISMANTLED (not sailing; full restoration required).

Why She Matters
If confirmed as Johan Anker’s Corona (1913), Xenon is a rare pre-war Scandinavian Twelve with direct links to one of Europe’s greatest metre-class designers. Her hull form and scantlings embody the transition from yawl-rated 12.5-Sailmetres to 12-Metre Rule cutters just before WWI, placing her squarely within the formative era of the class. Properly restored, she would be a museum-grade competitor eligible for Vintage 12mR regattas and a centerpiece for Nordic metre-class heritage.
