World’s finest Explorer Yachts
Aluminium yachts for high-latitude and
sustainable sailing adventures
We are KM Yachtbuilders
Since 1998, KM Yachtbuilders has pioneered the construction of innovative aluminum explorer yachts, always guided by the principles of safety and adventure.
Over the years, we have grown into a team of 80 dedicated professionals and have built more than 100 yachts. Today, decades later, our vessels continue to explore the world’s oceans, from pole to pole, carrying forward our legacy of craftsmanship, reliability, and a spirit of adventure.
Built for high-latitude adventure
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.
KM Open Day 2025 Recap
The KM Yachtbuilders Open Day on 10 May was a fantastic event
Visitors had the opportunity to explore more than 20 custom-built yachts, witness expert craftsmanship up close, and get an exclusive behind-the-scenes look at yachts under construction and exciting refits.
Take a look at our recap of this memorable day
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.
