But solar-electric yachts produce much less climate-warming pollution and provide a quieter ride. Bell: “It’s an incredible experience to literally cruise for three or four hours and have zero noise, just the noise of the water passing by.”That’s Steve Bell of Silent Yachts. He says Silent Yachts are perfect for short trips. To make the trip, he estimates that the Silent Yacht used about two-thirds less diesel than a conventional yacht would have. So solar-electric yachts could help move the industry toward a cleaner, quieter future.
