Hull Recovery Specialists

Advanced yacht hull restoration for vessels affected by osmosis and aggressive salt corrosion.

Our Marseille-based marine restoration team renews damaged hulls through careful inspection, moisture-controlled remediation, structural fairing, and resilient finishing systems. From blistered laminates and porous gelcoat to oxidized fittings and salt-stained underbodies, we rebuild hull integrity with technically disciplined repair steps, refined workmanship, and coatings prepared for long marina stays, offshore passages, and repeated haul-out cycles.

About Us

Technical restoration shaped by real marine exposure.

We believe hull repair should restore confidence as much as appearance. Built around marine finishers, laminate repair specialists, and practical shipyard coordinators, our workshop focuses on the difficult stages many cosmetic teams avoid: tracing moisture migration, opening compromised laminate zones, neutralizing corrosive contamination, and rebuilding hull surfaces so they perform under pressure rather than simply look clean at launch. Every project begins with condition mapping, substrate reading, and a realistic repair sequence tailored to the vessel’s material history, age, and service profile.

Our restoration approach balances structural respect with aesthetic discipline. We strip unstable coatings, dry affected areas with controlled timing, fair distorted surfaces, and reapply barrier and finishing layers with close attention to adhesion windows, environmental conditions, and long-term seawater exposure. That process supports older cruising yachts, charter boats, and performance hulls that need more than a quick polish after seasons of immersion, neglected maintenance, or prolonged berth corrosion.

Beyond repair execution, we help owners, captains, and brokers understand what was damaged, why it happened, and how to reduce recurrence. We coordinate practical maintenance schedules, corrosion-sensitive hardware checks, and coating care guidance so the restored hull remains easier to monitor through future haul-outs. The result is a service built around durability, transparency, and the belief that marine restoration should extend the useful life and visual value of a vessel without unnecessary shortcuts.

Company Advantages

Why owners choose a deeper remediation process.

Moisture-led diagnosis before cosmetic work

We do not cover damage with fresh coatings and optimistic promises. Each hull is first evaluated for blistering patterns, laminate moisture retention, prior repair inconsistency, and contamination around seams, fittings, and waterline transitions. That diagnostic discipline helps separate superficial oxidation from deeper osmosis cycles, preventing premature recoating and giving owners a repair path grounded in measurable conditions rather than assumptions made under time pressure.

Shipyard-ready corrosion treatment workflow

Salt corrosion rarely stays isolated to visible staining. Our sequence addresses embedded salt residues, oxidized fastener zones, compromised primers, and transition points between metal and composite surfaces. By integrating cleaning, preparation, material compatibility checks, and protective finishing into one workflow, we reduce the risk of patchy failures that often appear after rushed seasonal yard work or poorly matched marine products.

Fairness and finish quality in one service line

Many repair programs solve structural issues but leave hull lines visually uneven. We combine remediation with fairing refinement, surface leveling, and coating control so the restored hull reads cleanly both in the sling and in the water. This matters for owners who care about hydrodynamic cleanliness, broker presentation, and the pride of seeing a yacht return to service with a coherent, professional exterior rather than an obviously segmented repair history.

Transparent staging for owners and managers

Repair decisions become easier when progress is explained clearly. We communicate stages, expected drying periods, material choices, and surface preparation milestones so clients understand why some hulls can be completed quickly while others need additional stabilization time. That transparency supports better budgeting, more accurate relaunch planning, and fewer conflicts between technical necessity and operational scheduling.

Protection strategies tailored to ongoing marine use

A hull used for Mediterranean cruising, charter rotation, or extended marina residence experiences different stress profiles. Our finishing recommendations account for time afloat, cleaning habits, berth environment, and maintenance frequency so barrier systems and topcoat choices align with real vessel use. This practical alignment makes the restoration more durable and helps owners preserve the value of the work through future seasons instead of repeating reactive repairs.

Services

Restoration services built around damaged hull realities.

Osmosis assessment and blister remediation

We inspect laminate distress, map blister concentration, remove unstable material, and prepare affected zones for controlled drying and reconstruction. This service is designed for fiberglass hulls showing bubbling, sour-smelling laminate fluid, coating breakdown, or recurring moisture issues after prior repairs. By treating the cause rather than only the visible blister, we help restore structural reliability and improve confidence before new barrier systems are applied.

Salt corrosion cleaning and substrate stabilization

For hull zones exposed to aggressive salt accumulation and galvanic deterioration, we remove corrosive residues, address degraded surrounding materials, and rebuild the substrate so protective coatings have a stable base. This is especially useful around waterline transitions, fastener points, stern hardware areas, and neglected lower hull sections where corrosion spreads beneath seemingly minor surface damage.

Hull fairing, resurfacing, and finish preparation

After remediation, we restore line quality through fairing, abrasion sequencing, profile balancing, and finishing preparation. The objective is a hull that is not only repaired but visually coherent, smoother through the water, and better prepared for barrier coats, primers, and top finishing systems. Owners benefit from a cleaner presentation and a more technically complete restoration outcome.

Barrier coating and marine protection systems

We apply compatible marine barrier layers and protective systems chosen for repaired substrates, operating conditions, and expected maintenance cycles. Proper film build, curing control, and adhesion timing are treated as essential, not optional. This service helps shield the restored hull from renewed moisture penetration, chemical exposure, and recurring salt-related surface degradation.

Pre-sale and management condition support

We assist owners, managers, and brokers who need hull condition clarified before listing, transfer, insurance review, or maintenance planning. By documenting visible issues, repair priorities, and realistic restoration scope, we help clients approach negotiations and scheduling with clearer expectations. This is valuable when a vessel’s appearance hides deeper moisture or corrosion concerns that could affect value or handover timing.

Maintenance guidance after restoration

Once the hull returns to service, we provide practical guidance on washing routines, inspection intervals, haul-out checks, and coating care to help preserve the restoration. Good aftercare reduces avoidable deterioration and allows small warning signs to be identified before they expand into costly yard periods. The goal is to extend the value of the repair through disciplined ownership rather than repeated emergency intervention.
