What to do when the customer's desire for more living space becomes ever louder? At Silent Yachts, the answer is to add more. You take your 60, make it two feet longer using the hydraulic bathing platform and add a "storey" on top. Sounds easier than it is. The third deck offers three layout options: Open Skylounge with bar, galley and dining table, Closed Skylounge (pictured) or owner's suite with bathroom and private terrace. The owner is also spoilt for choice when it comes to electric propulsion: Cruiser (2 x 50 kW), E-Power (2 x 200 kW) or the fast (20 kn) E-Power Plus version with 2 x 340 kW. They are all quiet and clean. Info: www.silent-yachts.com
