Chameleon Yachts

I recently read about the Pendennis 157 Yacht MITseaAh
and how it is designed to "morph" from a sailing yacht to
a power yacht capable of over 20 knts. Achieving this with
telescopic rudders, swing keel and planing flaps.
The owner describes it as the worlds first "true superyacht"

I was swondering if this really is a first , or if there are other yachts
out there that can switch characters ??
