Serenity Yachts is promoting its Serenity 64, one of two models (with the Serenity 74) in the builder’s lineup of solar-powered yachts.

The Serenity 64 is built with a carbon-fiber hull, bulkheads, stringers, and can be customized to an owner’s wishes. PVC foam core adds rigidity and strength without weight. The main package has more than 700 square feet of SunPower solar panels, which the builder says allow for indefinite cruising at a speed of 4 to 6 knots—including the use of onboard amenities that draw power of their own.

Inside, creature comforts include four en suite staterooms, one crew cabin, and a galley-salon combination space. Other layouts are available. One setup creates a master suite that takes up an entire hull. In this layout, the galley and salon are combined into a single space on the main deck and there are two VIP staterooms with en suite heads. Another arrangement allows for dual master staterooms.


Owners can personalize their 64′s interior with woods such as wenge, oak, mahogany and more, as well as mahogany, teak or Amtico soles. Bulkheads can have a lacquer finish, fabric, vinyl or varnished veneers.

The helm is standard with a Garmin electronics suite and the galley is outfitted with equipment from Siemens and Samsung. The builder says other options are available upon request.

“We strive to lead the industry in green technology―the future of yachting―while continuing the luxurious, comfortable experiences that yachting provides,” Executive Director Boyd Taylor stated in a press release. “It is our passion to deliver vessels with solar technology that are performance-driven.”

About the Serenity 74: The bigger sister in the builder’s lineup has nearly 1,200 square feet of SunPower solar panels, which the builder says let her cruise at 7 to 9 knots.
