[ ABOUT THE COMPANY ]
WE BUILD MAST SYSTEMS FOR THOSE WHO NEVER COMPROMISE
When you’re out on the water, there is no room for compromise. A mast must perform – not just in theory, but in real life. In harsh weather. Under load. Offshore.
That’s why sailors around the world choose JOHN MAST.
With more than 50 years of experience and over 10,000 masts produced, we know exactly what works – and what doesn’t.
Each mast is designed, calculated and tested for its specific boat, rig setup and sail plan.
No standard profiles.
No guesswork.
We design and manufacture custom aluminium masts and complete rig solutions in Denmark.
The result is lighter constructions, optimal stiffness and precise balance throughout the rig — a solution engineered for performance cruisers, regatta yachts and bluewater yachts, where precision is critical.

GET THE RIGHT SOLUTION – BEFORE YOU DECIDE
We help you clarify what is technically the right solution – before you invest in a mast, rig or components.
[ OUR VALUES ]
Built on trust. Proven at sea.
When you sail, there is no room for doubt.
That’s why we build mast and rig systems with respect for both craftsmanship and the sea.
Our values are simple:
- We never compromise on construction or materials
- We design for real conditions – not catalogues
- We take responsibility for the entire solution, from calculation to finished rig
The result is not just a mast.
It’s confidence. Balance. And performance you can feel.
