#4 Blue - Top Largest Yachts in the World

4. Blue | 158m

Built in 2022, Germany

Taking her place at number four in the list of the world’s longest yachts, Lürssen’s Blue is so voluminous that she beats all the longer boats in terms of gross tonnage. Built for a Middle Eastern owner, she is exceeded for internal space only by those behemoths Dilbar (15,917GT) and Al Said (15,850GT). Terence Disdale has penned classic exterior lines with a sharply raked bow and gentle curves to the deep overhangs of the decks. The main helipad is positioned on the bow, with a smaller one aft. Other exterior features include a pool under cover on the main deck aft, a bathing platform at the stern and twin balconies flanking the owner’s cabin forward. Blue’s interior is designed to be timeless and rich in “feminine elegance”, a deliberate contrast to the exterior.

Blue is equipped with a diesel-electric hybrid propulsion system that was developed in-house. An electric Azimuth pod drive can manoeuvre the boat alone or in conjunction with the twin propeller shafts. To reduce noise, vibration and NOx levels, Blue has a state-of-the-art exhaust treatment system. The boat is also equipped with new membrane technology that means her treated waste water achieves drinking water quality.
