With their A100, Van Geest Design and Rob Doyle Design present a 100-metre-long dyna-rigged two-master that scores with plenty of interior space. At the centre of the innovative design is a redesign of the deck layout, in which the side decks have been significantly reduced. Now the search is on for a potential customer.

Van Geest Design and Rob Doyle Design present their A100, a yacht concept that aims to redefine traditional boundaries in sailing yacht design. According to the Dutch and British designers, the 100-metre design follows an approach that maximises interior volume without compromising sailing performance. The maximised volume is made possible by a main deck layout that benefits from the full width of the vessel. The designers claim the concept sets a new benchmark by offering interior spaces comparable to those of similarly sized motor yachts.

Space concept and main deck of the A100

The full-width main deck layout creates spacious interior areas. The owner's suite takes up the entire area and offers significantly more space than conventional sailing yachts of this size, of which there are currently only a handful. With a length of 100 metres, A100 would currently be the fourth largest sailing yacht in the world. A light-flooded lounge with a formal dining area forms the central living unit. There is also a separate area for a library or cinema. The continuous glazing of the superstructures provides natural light and panoramic views of the sea. The design emphasises the connection between indoor and outdoor areas. The clear lines, dominated by large curved glass panels, characterise the exterior appearance and create an aerodynamic look.

Lower deck and guest area

The lower deck is dedicated to guests and offers space for leisure and relaxation. A diving room and generous storage space for water toys such as e-foils and jet skis are integrated. The interior design favours contemporary styling with openness, abundant natural light and a strong connection to the sea. The design follows the concept of a comfortable and functional interior. The design teams emphasise that the spaces flow smoothly into one another while providing clearly defined areas for different activities. The layout allows guests to find both communal and private retreats.

Upper deck and outdoor areas

The upper deck houses steering and navigation areas as well as flexible lounge and wellness zones. At the stern is a full-width beach club that offers direct access to the water and spacious seating areas for relaxing. The bow of the A100 has space for dinghies and toys, which are integrated into the deck layout. The arrangement of the various living areas allows different activities to be carried out simultaneously without the areas interfering with each other.

Sail system and energy concept

The sailing performance of the A100 is supported by two free-standing DynaRig masts, as used on the 106 metre "Black Pearl and 88-metre "Maltese Falcon" are to be found. With this system, the sails can be moved out of the curved yards at the touch of a button, ensuring efficient sailing performance. The free-standing rotating masts are designed to simplify handling. The combination of sail system and energy concept aims to offer a more environmentally friendly alternative in the superyacht segment.

Design philosophy and collaboration

With the A100, Van Geest Design and Rob Doyle Design aim to present a new perspective on sailing yacht design. According to the studios, the visually striking concept balances technical innovation with a refined on-board environment, focussing on volume, efficiency and lifestyle. The collaboration between the two studios builds on previous joint projects.

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.
