Stadtship 56 ‘FLOW’
One of our latest deliveries: a robust all‑aluminium Stadtship 56 built for serious
bluewater sailing— from pole to pole and everywhere in between.
Go-anywhere yachts
Our aluminium explorer yachts are made for those who venture beyond the ordinary. Crafted for strength, reliability, and safety, they are built to withstand the world’s most challenging waters, from crossing vast oceans to navigating polar ice.
With every build, we stay true to our commitment: creating no-nonsense yachts that stand the test of time.

Refits
Is your yacht in need of maintenance, repairs or a large refit?
We’re happy to help you with that. We not only work on aluminium yachts but also on steel, polyester or wooden yachts.
KM Custom Yachts
A custom built yacht is a journey in itself. Every customer comes with their own set of demands that depend on the purpose of the boat. Decades of experience, teamwork and a profound love of our craft help us to always come up with solutions for the most challenging demands.
