The new Firmship 55 is a fast-sailing classic work ship archetype with a modern look. Centuries-old nautical traditions have been renewed by Studio Job with artistic design - without sacrificing functional comfort.

Firmship is more than a sturdy boat, it is a floating work of art.


Sea Level was founded in 1998 by naval architects Bastiën Ligthart and Jeroen van der Knaap. Based in Amsterdam and serving a global clientele, Sea Level employs a winning team of 15 naval architects.

When Sea Level was challenged by entrepreneur Casper Vissers to create the naval architectural design for Firmship in a close collaboration with artist Job Smeets for the aesthetic design, Bastiën and Jeroen didn't have to think long. The collaboration with Firmship is giving them the opportunity to work out of the normal naval box.

Together with Casper, Sea Level encouraged Job to create and complete the most beautiful and innovative ideas, after which the technical performers of Sea Level took care of the feasibility and performance of the ship.


Despite its sturdy functionality and artful aesthetics, no concessions have been made in terms of comfort. Inside the hut you experience a timeless nautical atmosphere. It is the warm teak and the silent light grey basis of all materials which makes this hut unique, peaceful and timeless.


The design and the detailing of our ships is radically timeless. The only way forward for a sustainable world. Every detail in our ships and our official collaborations have been designed and developed within this field of responsibility.

Studio Job likes to make fun of things as they are. “We don't just want to design a boat, we want to tell a story", explains Smeets. Hence the grey. Because grey is also synonymous with old and wise,

distinguished too. In one word: timeless. The Firmship is the archetype of the cabin boat. This boat is not only functional, it also looks functional. People should still like it fifty years from now."
