Yacht and Marine Vessels Design Xsr 85 Motor Yacht by Sarp Yachts In light of Sarp Yachts' environmental friendly vision and engineering background, they present its brand new hybrid propulsion concept yacht family. Xsr 85-105-125. Sarp Yachts has great passion for nature and concerned about water and air pollution. Yachts with conventional propulsion systems may not be the first guilty part for increasing pollution, but as a pioneering shipyard Sarp Yachts is aware of its responsibilities towards the environment. Therefore Xsr 85 will be built with the parallel hybrid propulsion systems; the best alternative for the fossil fuel.
