The Delcat 1350's hulls are constructed with balsa core planks (Durakore) and epoxy resin with knitted glass reinforcement using the strip plank method over male frames.   This produces very light but strong hulls.  All the flat panels such as the bulkheads and deck areas were constructed with Duflex panels.  DuFLEX consists of a lightweight core material sandwiched between two high performance epoxy reinforced laminates.  Internal fit-out is done with Duflex Honeycomb panels.  The emphasis with this cat is to keep it light so that it has a higher payload and better performance.  All these materials are produced by ATL Composites in Queensland.
