Bridging the gap between eco tech and superyacht design, Netherlands-based designer Xiang Yu has developed a mega yacht that harnessing renewable energy offers a sustainable sail without compromising the style and comfort of the luxury yachts. Dubbed the “Bloom,” the futuristic superyacht features a retractable wind/solar sail that blooms in the middle like a flower to harness wind and solar energy to power lighting system and electric motors, becoming a floating landmark in harmony with the society and the natural world. Employing the vertical-axis windmill and solar fabric to produce optimum renewable energy, the sail when not in use folds back into the yacht. Running on a hybrid diesel-electric motor system, the superyacht can reach a top speed of 20+ knots. Measuring 60m in length to provide adequate space to accommodate guests and crew in comfort, the Bloom also presents a 11.5m tall beam and 3m draught for a smooth sail.
