Our yacht refit, repair and maintenance services:

Aluminium repairs and structural work

Aluminium is our specialty. Whether it’s a dent from a buoy, damage caused by rocky shores in Norway, or a scrape from another yacht’s anchor, our team can restore your yacht to its original condition.

One of aluminium’s greatest advantages is its repairability. As builders of custom aluminium yachts for more than 25 years, we have the expertise to carry out everything from minor repairs to major structural modifications.

For bare aluminium hulls, repairs are carefully sanded and blended into the original structure. For painted yachts, our in-house paint halls ensure a flawless finish that matches the surrounding surfaces.

Services include:

  • Aluminium welding and fabrication
  • Hull and deck repairs
  • Structural modifications
  • Collision and grounding repairs

Painting and refinishing

Painting a yacht requires precision, experience and the right environment. Our dedicated paint halls, commissioned in 2023, provide optimal conditions for projects ranging from local repairs to complete hull and superstructure repaints.
