About Us. Custom Fiberglass International (CFI) has over 34 years experience in custom fiberglass fabrication. The FRP engineering and fabrication have ranged from the very simple to high tech laminations using composites and specialty resins. Nothing exhibits the design skill, fiberglass engineering and product production of CFI any better than the Isotope and Cheshire catamarans. These individualized catamarans are high tech performance sailboats.


CFI has recently been selected to make over life sized replicas of the human intestinal tract for a Medical Research Corporation.
