A new black mast installed on this beautiful Grand Soleil 43 😍

After completing this project, we received this message from the owner:

“You have a very satisfied customer and Steen, you can be proud of your son.”
Feedback like this means everything to our team.

A huge thank you to Claus for trusting us with his boat, and well done to Joachim and Morten for another successful installation!

At John Mast, every installation is the result of craftsmanship, precision and a passion for sailing.

Would you choose a classic aluminium mast or a black mast for your yacht?

Meet our Office Mascot, Nala 🐾

When she’s not supervising the office, she’s out at sea living her best skipper life 🐶⛵
Always first on deck, always ready for snacks, and apparently a very talented sailing mate too.

Safe to say Nala has officially become part of the crew at John Mast ❤️

Do you have a boat dog onboard too?
