Admiral 75-meter Explorer Project 575 Under Construction A new 75-meter explorer type yacht is presently under construction for Admiral Yachts. Come 2018 we will see the the globe-trotting yacht in person but for now we can view some renderings of the yacht. Immediately various facets about the design are somewhat reminiscent of a 90-meter build from Lurssen. Yes, if the names Air and Ice come to mind, that is exactly what we are hinting at. From the similar grey hull, to the transom and bow design as well as forward superstructure all look very close to the Lurssen "Ice".
