Composite hulls (fibreglass, polyester) are exposed to impacts, osmosis and wear. NV Marine handles the repair of damage: impacts, cracks, delamination and osmosis blisters. Every repair follows a rigorous protocol of sanding, drying, lamination and finishing to restore the original structural strength.
Beyond repair work, NV Marine fabricates custom composite parts: brackets, reinforcements, covers and deck fittings. Expertise in both polyester and epoxy resins allows each piece to be tailored to the specific requirements of your boat.
Preventive osmosis treatment is also available for hulls that show early signs, or as a precaution during antifouling.
In detail
Composite is the construction material of the vast majority of recreational boats. Its longevity depends on regular maintenance and meticulous repair of any damage. NV Marine carries out all types of work on fibreglass and epoxy structures.
Osmosis is the most common pathology affecting polyester hulls. It shows up as blisters on the underwater hull caused by water penetrating the laminate. NV Marine carries out the full osmosis treatment: sanding, opening of blisters, drying, and application of epoxy barrier coats. A treatment carried out to the highest standards protects the hull for several years.
Impact repairs (pontoon collisions, grounding, beaching) require careful structural work to guarantee watertightness and strength. NV Marine carries out replacement lamination, fairing and surface preparation for painting.
NV Marine also produces custom composite fabrications: winch pads, equipment brackets, deck repairs and hatch panels. Each piece is properly laminated for lasting strength.

Frequently asked questions
How do you recognise osmosis on a hull?
Osmosis shows up as blisters on the underwater hull, visible during antifouling. When pressed, a whitish liquid may seep out. This is a sign that treatment is needed.
Is osmosis treatment permanent?
A carefully executed treatment, with full drying of the hull and application of several epoxy barrier coats, provides effective protection for 5 to 10 years depending on conditions of use.
Can a hull be repaired invisibly?
A well-executed repair that is properly painted is virtually invisible. The quality of the preparation and finishing determines the final appearance.
Can NV Marine fabricate custom composite parts?
Yes, NV Marine produces custom fabrications in fibreglass and epoxy: brackets, pads, covers and panels. Contact us to discuss your requirements.
How long does an osmosis treatment take?
The treatment depends on the condition of the hull. Allow at least one week for a thorough treatment including drying, preparation and application of protective coats.
