DRETTMANN MOTORYACHTS – NEW FREEDOM

OPEN SPACES
You can only expect new answers if you ask new questions. That was the basic idea that led to
the development of the new Drettmann Motor Yachts, in which we took the usual as a starting
point for the creation of something totally unusual.
As for the questions we asked: they fundamentally involved taking a critical look at what was
already available. What do today‘s 20 to 37-metre yachts look like? What could make them look
better and function better? And above all: how have the wishes and demands of the owners
changed – and how do we consequently have to change our approach? Just a quick glance at the
outcome immediately reveals that we came up with convincing answers to all these questions.
One of the prime innovations is that the new lines have said goodbye to a classic design feature,
namely the clear distinction between vol-uminous hull and superstructures. This has been waived
in favour of an organic shape which gives the yacht an artistic, almost sculptural appearance.
Added elegance, but not at the cost of space. On the contrary: an intelligent layout means the
interior is actually astonishingly roomy. Combined with interior design that is geared to clarity,
finely tuned colour schemes and simple yet surprisingly varied purism, this all adds up to a
completely new yacht feeling – one of being on a far larger class of yacht.
That is a decidedly good feeling – and one that is intensified by a number of highly interesting and
thoroughly unusual features. The idea, for example, of not confining owner and guests to the hull,
but placing them as close to the water as possible led to a totally new solution for this class of
yacht. A beach club at the stern with bar, retractable swimming platforms at the sides for bathing
or simply chilling right beside the water. Or a main saloon that is open on three sides, cleverly and
comfortably abolishing the boundaries between interior and exterior. „These new comfort zones
provide endless new opportunities, above all, direct access to the sea. This enhances the quality
of all these things that make life on board interesting – whether swimming, diving, jet-skiing,
dining, partying or simply sunbathing,“ sums up Albert Drettmann. The enthusiastic reaction from
the public at the Düsseldorf Boat Show in January was ample proof that this description of the
DMY line is no exaggeration.
