102m Lürssen superyacht Jassi launched

6 February 2026 • Written by Emily Dawkins

 Lürssen's 102.4-metre superyacht Jassi, previously known as Project Jassj, has been launched at the German shipyard's Rendsburg facilities. 

This marks the first time the yacht has been seen since she was technically launched into the Kiel Canal in December 2023. Despite still being shrouded in secrecy, the full-displacement, steel and aluminium motor yacht is known to feature interior and exterior design by British design studio RWD, with accommodation for 22 guests in 11 cabins and a crew of 37. Other key numbers include a 15-metre beam and a 3.9-metre draught.

Jassi was technically launched in 2023

Images now reveal Jassi's traditional flared bow topped with a foredeck helipad, while taut lines and an extensive use of curved glass define her cool grey profile. The 3,420GT yacht was sold in 2021 by Moran Yacht & Ship and began construction in 2022, according to BOATPro. Delivery is expected in Q3 of 2026.

Exclusive BOATPro data shows Jassi to be one of 10 other yachts measuring over 100 metres currently under construction at Lürssen. The launch comes at a busy time for the German shipyard following the recent news that its 110-metre new build O3 was undergoing sea trials.
