Refit
A new and exciting chapter in the life of a ship and her owner. The perfect opportunity to update and modify a yacht to a new design look and feel, new standards, sustainable technologies, increasing digitalization and perform annual services to technical systems.

How we refit yachts
- Driven by flexibility
No project is considered small or large. From only facilitating to fully managed execution. Zwijnenburg Yachting takes care of it together.
- Facility use
Efficiency is linked to location. Whether alongside or organising a docking. Zwijnenburg is located in the Mainport of Rotterdam close to partners and suppliers.
- Expertise in control
Control means early involvement, detailed preparation, well planned execution and taking care after delivery. Control is the key to success.
