"Crystal" is the name given by the Dutch design office Mulder Design to its latest 70-metre concept, which clearly has explorer genes with its large heli-platform and ice class 1C.

However, "Crystal" does not sail as an icebreaker or fishing companion. The designers have therefore not forgotten about spectacular effects beyond any considerations of practicality and pure utility. "One of the most striking features of our new design is a glass atrium, in which a staircase connects four decks and provides plenty of light in the interior," Frank Mulder began the concept description at the MYS in September.

The experienced naval architect founded his design studio 40 years ago and has been running the company together with his son Bas since 2000. The reference list of the designers is long and peppered with some spectacular formats. These include what is still the fastest yacht in the world, "The World is not Enough", and the 53-knot "Octopussy", which was commissioned by US owner and James Bond fan John Staluppi.
The trend towards lots of glass in the superstructures continues. After the 80 metre long "Artefact", which is currently being built at Nobiskrug and is known throughout the industry as a "glass yacht" due to the 70 tonnes of glass in the hull and superstructure, the next glass superlative is entering the large yacht stage with the 70 metre long "Crystal".

Fancy some technical buzzwords? "Diesel bunkers and hull lines allow a range of 10,000 nautical miles. This could attract adventurous owners to polar regions." Customers can choose between three propulsion systems: a conventional drive train consisting of two diesel engines that transmit their power to the shafts, a hybrid package (diesel and electric motors) or a diesel-electric unit that works on pods.
The interior design and layout have not yet been finalised, but Mulder is reserving an entire deck for the owner. The charter mode limits "Crystal" to twelve guests. If the owner is travelling, the number rises to a maximum of 14. 18 crew members take care of navigation and service.

As befits an explorer suitable for expeditions, Mulder has equipped the 13.20 metre wide steel-aluminium displacement vessel with a helideck for tenders weighing up to four tonnes. Underneath, on the pool deck, a selection of toys, a submarine and two tenders are stored. "The view from the glass atrium will be spectacular," says Mulder confidently. "Especially when a helicopter swoops in." mulderdesign.nl

Martin Hager

Editor in Chief YACHT

Martin Hager is editor-in-chief of the titles YACHT and BOOTE EXCLUSIV and has been working for Delius Klasing Verlag for 20 years. He was born in Heidelberg in 1978 and started sailing at the age of six, in an Opti of course. This was soon followed by 420s, Sprinta Sport and 470s, which he also sailed on the regatta course with his brother. His parents regularly took him on charter trips through the Greek and Balearic Islands. Even at a young age, it was clear to him that he wanted to turn his passion for water sports into a career. After graduating from high school and completing an internship at the Rathje boatbuilding company in Kiel, it was clear that he did not want to become a classic boatbuilder. Instead, he successfully studied shipbuilding and marine engineering in the Schleswig-Holstein state capital and focused on yacht design wherever he could. His diploma thesis dealt with the “Testing of a new speed prediction method for sailing yachts”. In 2004, the superyacht magazine BOOTE EXCLUSIV was looking for an editor with technical and nautical background knowledge, a position that was perfect for Martin Hager. The application was successful and a two-year traineeship was arranged. After twelve years as an editor, the editorial team changed and he took over responsibility for BOOTE EXCLUSIV as editor-in-chief in 2017. After long-time YACHT editor-in-chief Jochen Rieker moved to the role of publisher, Martin Hager also took over the position of editor-in-chief of Europe's largest sailing magazine YACHT, which is celebrating its 120th anniversary this year, at the beginning of 2023. When he's not working on topics for the two water sports titles, Martin Hager likes to go out on the water himself - preferably with kite and wingfoil equipment or on a little after-work trip across the Alster.
