34-meter "Solis" Launches At Mulder Yachts The 34-meter "Solis" now assumes flagship status at Dutch builder Mulder Yachts since she was launched. Previously known simply as the Mulder 'Thirty-Four', the new yacht displays her new name from sideboards. A stylish but subdued cream hull contrasts the gleaming white aluminium superstructure and silver-grey hardtop. We know you are wondering who designed the new flagship of Mulder Yachts. That answer comes in the form of Claydon Reeves - yes British design firm Claydon Reeves. They were responsible for both the exterior and interior of Solis while the Naval Architecture work stayed in The Netherlands with Van Oossaneen. The Mulder has a GT from 315 tons and will be built under RINA LY3, MCA classification and Unlimited Range.
