Nearly everything is getting a sustainable makeover, even luxury yachts, apparently. Grand Cayman-based Serenity Yachts just showed off two of their new designs for solar-powered yachts at the Miami International Boat show.
The Serenity 64 and Serenity 74 will go for $3.3 million and $5.5 million, respectively. So far, two of the 64 have been produced, while the 74 is still in production. The yachts are designed to maximize efficiency while maintaining a smooth ride, according to Serenity.
