The Dutch shipyard Holland Jachtbouw has announced that the 42.7m J Class yacht, Topaz has been launched from its Zaandam shipyard. She has the longest waterline length of any J Class to date, at 26.8m, a low wetted surface area and the highest keel aspect ratio of all Js. 

Created by Hoek Design, Topaz is based on the work of Frank C. Paine, famous for the design of the 1930 J Class yacht, Yankee, the only J that could compete against much larger yachts. Hoek commented, “The hull lines of J8 proved to be very fast in an extensive research project that the office undertook.”

Topaz has a double cockpit and deckhouse layout, with the helm station amidship, positioned in front of the aft deckhouse. RSB Rigging solutions will supply the running rigging package.

The Hull of Topaz was built at Bloemsma Aluminiumbouw and then transferred to HJB for completion.

Topaz is expected to be delivered in July.
