Resins, and composites with a resin matrix, provide materials that are strong, lightweight, corrosion-resistant and dimensionally stable. These materials also provide good design flexibility, a high dielectric strength, and usually require lower tooling costs. Their tremendous strength-to-weight and design flexibility make them ideal in nautical applications.

They are widely used in the building of recreational boat hulls and products destined to permanent water contact such as competition boats, surf-boards etc. Manufacturers of these products require materials that have a high degree of resistance to impact.
