Built by Feadship in 2015 as the Dutch yard’s first true eco-friendly motor yacht, Savannah is equipped with special ‘green’ features such as a highly efficient hull design and a single efficient-speed Wärtsilä diesel engine that drives a central propeller shaft linked to a variable pitch propeller. Feadship worked in partnership with CG Design to create her iconic exterior look and contemporary interior. Onboard, one of her most notable features is her unique underwater lounge located on the port sub deck aft, where guests can experience the underwater life from the comfort of their seats.
