Secretive 78m Lürssen superyacht Ace 21 on sea trials

5 August 2025 • Written by Dea Jusufi

The secretive, 78-metre Lürssen project Ace 21 is now embarking on sea trials off the coast of Bremen, Germany. The superyacht was glimpsed for the first time earlier this year, while being transported between halls at the shipyard's Lemwerder site.

Her design team is yet to be revealed but the initial imagery shows five decks, clean lines and a plumb bow. Other confirmed details include a volume of 2,500GT and a steel and aluminium build. Delivery is scheduled for this September, according to BOATPro.

Ace 21 is one of 10 projects currently under construction at Lürssen, including the 134.2-metre Project Deep Blue – launched this June – the 114.2-metre Project Cosmos and the 107-metre Shackleton, previously known as Project Icecap.

Last year, Lürssen celebrated the delivery of another elusive vessel, the 142.1-metre Dragonfly. Highlights include an interior volume of approximately 9,500GT, which houses a glass-bottom pool on the main deck, a cinema, spa and a water sports centre, among other amenities.
