Professionals Building Solutions for Professionals
Ultimate Maritime Solutions was founded by professionals who have spent their lives at sea and in shipbuilding. We are not a traditional shipyard. We are a highly specialised maritime manufactory that combines practical operational insight with advanced engineering and the flexibility to develop highly efficient, tailor-made catamaran platforms.
Unlike large corporations, we are not constrained by complex organisational structures or lengthy decision-making processes. This allows customer requirements to be addressed quickly, pragmatically and without compromise.
UMS is led by Olaf Steckstor, Master Mariner, former officer of the German Navy, former First Officer and Captain of the NATO Research Vessel ALLIANCE, former superyacht captain and project manager on some of the world’s most demanding newbuild and refit projects.
