About Navalmartin

Navalmartin is a multidisciplinary marine firm established in 2012 by naval architects: Daria Cabai and Val Martin. Specialising in yacht design, offshore projects, marine surveying and technical marine consulting, we have a global reach with headquarters in London and floating offices in Europe and the Caribbean.

Driven by craftsmanship, innovation and an immeasurable love of sailing our unique range of services evolve with the ever changing needs and challenges presented at sea. As accomplished naval architects and marine designers, our objective has always been to create beautiful yachts and effective solutions, starting from the principle that everything is possible. From cutting-edge yacht design to providing meticulous technical expertise, our many years of experience within the marine industry and insurance equips us well to bring visions to life and solve problems no matter how complex.

Inspired by what is yet to come, rather than what has been, we are deeply motivated to create the future – one which is more sustainable, inclusive and safer. In 2022, we won a top award for disrupting  tech for mir, a remote surveying app designed to reduce the human and environmental risk associated with aging vessels. We are ambitious and optimistic. By modernising areas of the marine industry with technology, our goal is to not only make significant and positive change but to create new opportunities.

Our work starts with the principle that everything is possible.

Fine-tuned over the past decade, our diverse range of services allows us to create, challenge and solve from an entirely unique perspective. Our combined curosity, expertise and dedication to creating the best possible outcomes has made us a valued partner.
