Composite Repair

Using composites in boat building and repair is highly complex and requires expert skills and knowledge to ensure it is carried out correctly. From carefully calculating exactly how much fibre material and resin is required make sure a race yacht is as light as possible without losing any of the structural strength when under load, to carefully feathering in repairs, to creating a smooth neat finish around a mould, composite construction and repair is both a science and a fine art.

What Are Composites?

In the marine industry, composites are used to build new boats, new boat parts and to modify or repair existing hulls, interiors and equipment. The most common composites used are resin combined with e-glass, s-glass, aramid (kevlar) or carbon fibre to create a strong, durable and lightweight material that is incredibly versatile and can be used for many different boat repairs and modifications.

Why Use Composites?

There are many benefits to using composite materials in boat building, refits and repairs. Whichever combination of composite materials you use, you can expect a strong and durable, lightweight material that is very easy to maintain.
Benefits of Composites:

  • High Stiffness for the weight
  • Low maintenance
  • Ability to mould complex structures and shapes
  • Less corrosion
  • Becoming more affordable

Our Composite Services
Composite Boat Building

Many modern boat hulls are now made entirely from composites. Multiple layers of fibres and a foam or Nomex (honeycomb) core are laid in or on moulds and then bonded together with resins. Composite hulls are strong and very lightweight in comparison to traditional wood or steel structures, and fibreglass has been a popular choice of composite for boat hulls for many years now. However, we are now seeing an increase in carbon composites for new race yacht builds where the weight saving benefits are fundamental to their performance and speed.

Composite Components and Modifications

Composites are becoming the material of choice for boat refits and modifications. A vast array of new structures, components and accessories can be crafted using composites which are lightweight and more affordable than ever before. Whether you need new foils, stanchions, a bracket for your navigation equipment or even just a new saloon table, composite construction provides you with a durable, lightweight option that can be customised to suit your own requirements and fit.



Composite Rig and Spar Building

An improvement in carbon composite techniques and cost has seen and an influx of carbon masts and spars over recent years. A progressive step away from aluminium, carbon spars are stiffer, durable and extremely lightweight making them an essential choice for racing yachts as well as high performance and luxury cruisers.


Composite Boat and Spar Repair

Assessing composite damage is undertaken by means of Non Destructive Testing (NDT). Using NDT tools, the damage can be mapped and evaluated before any physical removal of material. Once the repair site has been established the work can usually be carried out without impacting the rest of the vessel significantly. However, it is a very specialist skill which involves scarfing the original layers and carefully laying in new ones to ensure structural strength is not compromised. If done well, composite repairs can be blended into a near invisible restoration.
