Fiberglass Boat Building Supplies
Fiberglass is a weather-resistant material that is easy to use over wood or other composite materials. For nearly a century, fiberglass boat building has been a cornerstone in the marine industry due to its strength, lightweight, and stability. It does not expand or contract, making it an ideal choice for boat construction. When combined with various epoxy resins, fiberglass becomes even more versatile and cost-effective.Why Choose Fiberglass for Boat Building?
Fiberglass is favored in boat building for several reasons:- Durability: Resistant to weather and water damage.
- Strength: Provides robust structural integrity.
- Lightweight: Easier to handle and more fuel-efficient.
- Versatility: Can be used with different resins and materials.
Types of Fiberglass Materials
At Fisheries Supply, we offer a wide range of fiberglass boat building materials:- Fiberglass Cloth: Available in various sizes for different applications.
- Fiberglass Tape: Ideal boat fiberglass strips for reinforcing seams and joints.
- E-glass Biaxial Cloth: Provides excellent strength and durability.
- Woven Roving: Used to reinforce composite materials, providing high strength and durability in boat building and repair.
- Fiberglass Matting: Non-woven material used in composite construction, offering excellent bonding and strength.
Polyester, Vinylester, and Epoxy Resins for Boat Building
Epoxy resins are crucial in fiberglass boat building for bonding, moisture barriers, and structural reinforcement. Fisheries Supply provides top marine brands of epoxy resin kits, including:- Heat-Resistant Epoxies: Suitable for high-temperature applications.
- Fast and Slow Hardeners: Allow for controlled curing times.
- Polyester and Vinylester Resins: Offer flexibility and durability for different parts of the boat. However, they are not as strong as boat epoxy resins.
- Epoxy resins: Strong, durable adhesives used in boat building and repairs, providing excellent bonding and water resistance. Also the most expensive type of resin.

Which resin should I use for underwater boat repairs?
For underwater repairs or areas requiring maximum water resistance and strength, epoxy resin or vinyl ester resin are the best choices. Epoxy provides the strongest bond to existing surfaces, while vinyl ester offers excellent resistance to water penetration and osmotic blistering at a mid-range price point.
Can I use fiberglass mat with epoxy resin?
Generally, standard chopped strand mat (CSM) should not be used with epoxy resin because the binder holding the mat together is designed to dissolve in the styrene found in polyester or vinyl ester resins. If used with epoxy, the binder will not dissolve, making it difficult to fully saturate and form the fabric.
What is the difference between polyester and epoxy resins?
Polyester resin is the most affordable and offers good UV resistance, but it has lower adhesive strength and higher shrinkage than epoxy. Epoxy resin is more expensive but provides superior bonding strength, durability, and water resistance, making it better for structural repairs.
How do I choose the right fiberglass cloth weight?
The weight depends on the application: 4 oz. cloth is lightweight and nearly transparent, ideal for protective wood coatings; 6 oz. is a versatile middle-ground for general repairs; and 10 oz. or heavier woven roving is used for structural layups and building laminate thickness.
