The requirements of sustainable development of the economy force the replacement of the previously used composite materials in the production of elements not only with lighter, but also more durable materials. These materials should meet more and more stringent environmental protection requirements. This study aimed to determine the possibility of introducing a polymer structural composite reinforced with natural fiber into the structure of the hull of vessels instead of the commonly used polymer-glass composite (GFRP). The hemp fabric was used to reinforce the polymer matrix. The compared analysis of the physical properties of the classic GFRP composites with obtained new HFRP composites, i.e. density, impact strength, as well as resistance to static tensile and bending, was carried out. As a result of the performed analyzes and comparison of the results with the standards, it can be concluded that it is possible to apply a polymer-hemp (HFRP) composite for the shipbuilding and boatbuilding needs – limited to plating elements with medium and low strength requirements.
