Little is known about Lürssen’s 156-metre Project Omar (even the LOA is unconfirmed), the fourth largest superyacht ever built and said to be the biggest ever in terms of internal volume. There appears to be at least five decks above the main deck, and she is constructed in steel and aluminium. She was first seen on the water in April on a floating dock, and is expected to be handed over next year.

There is some suggestion that the yacht’s name – currently covered – is Dilbar, the same as the 110-metre Tim Heywood design launched at Lürssen in 2008. The yard delivered the 180-metre Azzam – the largest superyacht in terms of LOA ever built – in 2013.
