Composites Use in Marine Applications
Infused, fiberglass/polyester composite boat hulls have been built since the mid-1900s, expanding over time to include additional resins and foam cores. Composites continue to be a mainstay for various types of boats and luxury and racing yachts, and now include newer innovations such as carbon fiber precision hydrofoils and recycled carbon fiber or bio-based resins.

FAQ: Marine
How are composites used in boatbuilding?
Boats and yachts have featured fiberglass composite boat hulls, decks and other structures for many years. These are typically fabricated via infusion, hand layup and/or sprayup methods. Carbon fiber/epoxy can be used in applications requiring even lighter weight to increase speed or fuel efficiency, such as in sailing boats or racing boats.
More recently, new international regulations have allowed developments in composite decks, superstructures, rudders and other components for large ships as well.
Why use composites in boatbuilding and marine applications?
- Composites are attractive in marine applications due to corrosion resistance, as well as lightweighting that composites can provide compared to metals or wood can reduce fuel use, greenhouse gas emissions and vessel draft, helping to improve sustainability.
