New Yacht Skat

In May 2020 Lurssen launched a 90 meter + yacht, with similar styling as the current Skat. The yacht (or actually just the steel hull) was bearing the Hungarian, Swedish and US flags. This is a direct link with Simonyi, as he was born in Hungary, his wife Lisa was born in Sweden. And they live in the US.

The new yacht has a similar styled sky lounge as the current yacht. The biggest difference is a wave piercing bow.
