KM Services — Refit, Repair & Maintenance under one roof:

Aluminium Repairs

Aluminium is our specialty. Whether it’s a dent from a buoy, damage from rocky shores in Norway, or a scrape from another yacht’s anchor, we’ve got you covered. One of aluminium’s key advantages is its repairability — allowing us to restore your yacht efficiently and effectively.

  • Bare hull? We sand and blend repairs seamlessly into the original structure.
  • Painted hull? We use our in-house paint hall for a flawless finish.

Whatever the challenge, we return your yacht to peak condition — ready for the next adventure.

Deck Solutions

More and more owners are moving beyond traditional teak. We offer modern alternatives to give your deck a fresh, durable look — from sandblasting and anti-skid wrapping foils, to high-quality modified wood or man-made composites like Esthec: long-lasting, low-maintenance, and available in custom colours and patterns.

Engine & Propulsion

From winterising to complete overhauls, or even full engine replacement — our in-house engineers handle it all. We offer:

  • Preventative maintenance
  • Repairs and diagnostics
  • Hybrid and electric propulsion upgrades
  • Complete new installations

Interior Work

From a fresh coat of paint or new upholstery to a complete interior transformation — our carpenters are true specialists. We craft trims, decks, cabinets, and custom furniture from any wood type to suit your style and needs.

Maintenance

Preventive maintenance is essential for safety and longevity. Each year we welcome yachts of all sizes for regular servicing — keeping them in prime condition, season after season.

Painting

Painting your yacht demands precision. Our fully equipped paint halls — new in 2023 — are in constant use for both in-house and third-party projects. We ensure a smooth, high-quality finish that matches the standard your yacht deserves.

Rigging

From insurance inspections to performance upgrades, we maintain masts, booms, and all types of rigging. Our expert team ensures your yacht sails safely and efficiently.

Electrical Systems

On aluminium yachts, electrical systems demand extra attention. Concerned about electrolysis or electrical integrity? We’ll inspect, advise, and make the necessary corrections to keep your yacht safe and sound.

Sustainability

Embracing life on the water also means protecting it for future generations. Explore how we can help you
and your yacht contribute to a healthier planet.

From electrifying your engine or integrating a hybrid solution to adding solar panels, installing a water generator, or upgrading to Li-ion batteries— every step reduces your environmental impact.
Let’s work together to sail sustainably and leave a positive mark on the world.

Customer care

Our commitment doesn’t stop after delivery. Carefree ownership is all-important to us. We provide peace of mind by keeping your yacht in peak condition and supporting owners with a full range of exceptional services.
