ROCK 85 strikes the ideal combination between speed, comfort, and spaciousness. Vripack designed a fast super displacement hull with a high, straight bow for intercepting rough seas. With an innovative sliding platform and a draft of only 1.8 meters, she can visit the most secluded areas in pursuit of adventure. All of this, combined with the yacht’s steel and aluminum construction, results in a remarkably comfortable cruising experience with impressive speeds. Furthermore, at only 24 meters, ROCK 85 retains all of the benefits of the European CE rules’ CE-A category.

Additionally, ROCK 85 excels in providing unparalleled comfort and space to its discerning owners and guests. With a beam of 6.5 meters and three decks, the yacht’s voluminous, open-plan layout boasts 20% more internal volume than other comparable-sized boats. She can accommodate eight guests and four crew in a volume of 145GT.

On the main deck, full-height windows give amazing uninterrupted views onto the water. This space has a lounge area with adjustable seating and a fully equipped minibar, while the dining area, which can seat up to 12, features one of the largest glass panels found on a yacht this size. The owner’s suite is on this level, characterized by a private drop-down balcony with underwater lighting and child-proofing features available at the press of a button. There are three guest cabins on the lower deck, a double and two twins, and the 15-square-metre bridge deck is given over to relaxing, with seating and al fresco dining. Sunshades create a further outdoor space on the main deck.

Vessel Details

A Message from a Current ROCK Owner:

search was for a boat that was neither too big nor too small, a boat on
which one can spend six to eight months a year. In other words, a home
on the sea, says Mark Meier Von Strenght, owner and captain of 26-metre
M/Y ROCK, hull number one. With a total of 16,000 nautical miles
traveled so far, that’s about 4,000 nautical miles per year, we have
experienced every kind of weather and have never felt unsafe, even in 70
knots of wind and four-meter high waves.”


explorer yacht like no other, M/Y ROCK is the SUV of the seas. Inspired
by the durability of marble and Land Rover, yet softened by the warmth
of a tactile interior, 24m ROCK, designed by Dutch studio Vripack, is
built for comfortable adventure.

an SUV of the seas, is the perfect example of how to take a
contemporary explorer yacht to the next level. Underpinned by Vripack’s
creative design skills and expertise in the fields of naval architecture
and engineering, the end result is a unique home at sea. Clever space
planning and an ergonomic layout creates optimum room on board, far
exceeding the interior volume of any other comparable sized yacht Paired
with CFD optimized hull shape- a defining feature of the SUV series-
ROCK epitomizes Vripack’s renowned skill for smart design, maximum
comfort, and pure onboard enjoyment in any sea condition.” – Bart M.
Bouwhuis, Partner, Vripack


mission is more about creeping into far-flung corners of Med with her
1.8 meter draft, or exploring off the beaten track in the Caribbean.
That’s why the SUV moniker sits so well. She is something of a hybrid. A
crossover. A new breed.” – Boat International

added a lot of glass on board, with full height windows that deliver
uninterrupted views wherever you are on board. The dining area features
one of the largest glass panels found on board a 26m yacht, providing
panoramic vistas.” – Robin De Vries, Senior Designer, Vripack

Vripack design team took great care in developing a detailed exterior
and interior design to contain a large number of custom features that
match ROCK’s architectural lines. This is most apparent in the stainless
steel railing and bollards, the teak-deck layout, detailing on the
windows and inside the leather paneling and marble works that run
throughout. Evident from the moment you step on board, ROCK’s
exceptional design elements are what make a yacht of this size a
standout custom design. The special cabins at the aft gives the total
effect of the cruising experience with extra large windows making the
cabins luminous. Both cabins have their own bathrooms. The Owner Cabin
has luminous space and a private terrace which become stunning
especially at night with utilized underwater lighting enjoying an
aquarium feeling.
