Six Pillars of Superyacht Excellence

Each discipline is executed by dedicated master craftsmen under classification society oversight, ensuring every modification meets the highest maritime engineering standards.

Custom Metalwork & Fabrication

Precision-engineered bespoke components in marine-grade 316L stainless, aerospace-grade aluminum alloys, and carbon fiber composites. Every piece fabricated to ±0.1mm tolerances with full MTR traceability.

  • 316L Stainless & Duplex Steel
  • 6061-T6 / 7075-T6 Aluminium
  • Carbon Fibre Reinforced Polymer (CFRP)

Architectural Refits

Full-envelope interior and exterior transformation programs for vessels of any classification. We collaborate with leading naval architects to redesign superstructures, reconfigure deck layouts, and re-engineer stability calculations.

  • Naval Architecture Collaboration
  • Stability Recalculation & Certification
  • Lloyd's Register / DNV GL Approval

Propulsion & Systems Engineering

Advanced propulsion optimisation, hybrid-electric integration, thruster upgrades, and full drive-train engineering. Our certified engineers work directly with MTU, Rolls-Royce Marine, and Caterpillar powertrain systems.

  • MTU / Rolls-Royce / CAT Integration
  • Hybrid-Electric Architecture
  • Thruster & Stabiliser Systems

Deck & Superstructure

Topside modification programs including custom teak deck installations, pool and Jacuzzi integration, helipad construction and certification, solar array embedding, and fully bespoke outdoor furniture fabrication.

  • CAA / FAA Helipad Certification
  • Teak & Hardwood Systems
  • Pool & Water Feature Integration

Tender & Toy Integration

Custom-engineered garage systems for tenders up to 15m LOA, hydraulic launch platforms, personal watercraft storage, submersible integration, and fully automated handling systems with class-approved load calculations.

  • Hydraulic Launch Systems
  • Submersible & Mini-Sub Garages
  • Automated Handling Certification

Materials & Coatings Engineering

Specification and application of advanced marine coatings systems including Awlgrip topcoats, Hempel fouling protection, and custom Pantone-matched exterior paint programs. Anti-corrosion systems for tropical and arctic operating profiles.

  • Awlgrip & International Paint
  • Anti-Corrosion Systems
  • Custom Livery Programmes

Common Questions

Frequently Asked Questions

What superyacht modification services does Maritime Mods offer?
Maritime Mods provides bespoke fabrication, full architectural refits, custom deck and superstructure modifications, advanced propulsion system engineering, tender integration systems, and aerospace-grade materials engineering for superyachts exceeding 30 meters LOA.
What is the typical lead time for a bespoke superyacht fabrication project?
Project timelines vary by scope and complexity. A focused custom fabrication module typically requires 8–24 weeks. A full architectural refit for a vessel above 60m LOA typically spans 18–36 months, inclusive of design, engineering, fabrication, and commissioning phases.
What materials does Maritime Mods work with?
We engineer with marine-grade 316L stainless steel, teak and hardwood composites, aerospace aluminium alloys (6061-T6, 7075-T6), carbon fibre reinforced polymers, and custom toughened glass structures. All materials meet or exceed Lloyd's Register and DNV GL classification society standards.
