Yacht Composites & Fibreglass in Mallorca

WE REBUILD STRENGTH WHERE IT MATTERS MOST.

Heavy Seas provides specialist yacht composites and fibreglass services in Mallorca, covering structural repairs, surface restoration and bespoke fabrication for yachts and superyachts.

Our technicians work with fibreglass, carbon fibre, gelcoat and advanced marine composites, selecting the appropriate materials and techniques according to the structure, application and extent of the work.

From localised damage to complex refit work, every project is approached with a focus on structural integrity, technical accuracy and a clean finish.

For projects requiring specialist surface finishing, Heavy Seas works alongside Hull Pro, our dedicated yacht finishing team, providing expertise in gelcoat restoration, polishing, antifouling and protective coatings to ensure every vessel is completed to the highest standard.

Fibreglass Repairs & Structural Work

Fibreglass is used extensively throughout modern yacht construction, from hulls and decks to internal structures and technical areas. When cracks, impact damage or deterioration occur, repairs must restore both the original profile and the integrity of the affected structure.

Our fibreglass and composite repair work includes:

Each repair is prepared according to its location, construction and level of damage, using appropriate marine-grade materials and laminate systems.

Carbon Fibre, Gelcoat & Composite Finishing

Heavy Seas provides carbon fibre and gelcoat repairs for both structural and visible areas onboard.

Services includes:

Materials and repair methods are selected according to structural requirements, weight, rigidity, exposure and intended use.

For visible areas, particular attention is given to colour, surface preparation and finish so repairs blend naturally with the surrounding surface.

Composite Finishing & Refinishing

Following composite repairs and structural restoration, Hull Pro provides specialist finishing and refinishing solutions to bring each project to its final stage. Working alongside Heavy Seas’ refit team, their expertise covers gelcoat restoration, surface preparation, polishing and protective coatings, ensuring composite repairs are seamlessly integrated and finished to the highest standards.

Frequently Asked Questions

About Composites & Fibreglass

Can you match the existing gelcoat colour?

Yes. Colour matching is an important part of visible gelcoat repairs, helping the repaired area blend as closely as possible with the surrounding surface.

Can you manufacture completely new composite parts?

Yes. Heavy Seas can fabricate bespoke fibreglass, carbon fibre and other composite components according to the yacht's dimensions and technical requirements.

Do you carry out structural composite repairs?

Yes. Our team can undertake structural composite repairs depending on the location, extent of the damage and requirements of the vessel.

Can composite repairs be carried out while the yacht remains in the water?

It depends on the location and type of repair. Some minor or accessible work may be possible afloat, while structural repairs or work below the waterline will generally require the yacht to be hauled out.

How do I know whether fibreglass damage is cosmetic or structural?

Surface cracks, chips or gelcoat damage do not necessarily indicate structural failure. A technical inspection allows the depth and extent of the damage to be assessed and determines whether the underlying laminate has been affected.
