Silver Cloud is a private yacht owned by Alexander Dreyfoos.

It is a 134 ft SWATH (Small-Waterplane-Area Twin Hull) vessel, built by Abeking & Rasmussen in Lemwerder, Germany, in 2008.

[1] The SWATH technology was until 2008 primarily used only in pilot tenders, and military and research vessels.

The use of a pair of cylindrical hulls, a bit like small torpedoes, connected by slender struts to the superstructure places most of the ship's displacement below the water's surface, in calm water.

At the time the Silver Cloud was built, only an estimated 20 SWATH vessels were in use in the world.
