The safety of vessels at sea is crucial, given the potential presence of obstacles such as rocks, other vessels, or offshore structures. Impacts with such objects pose a significant risk to the integrity of ships and the safety of passengers. The present research activity explores safety in international nautical competitions, with a specific focus on races governed by the International Union of Motorboating (UIM). It analyzes the innovative design of the hull’s sandwich construction of the XCAT racing catamaran, crucial for ensuring safety in the event of violent impacts, such as those from capsizing. The research activity involved four-point bending tests and impact tests to evaluate the mechanical performance and impact resistance of these sandwich specimens. Two types of sandwich structures were subjected to bending tests to determine their load-bearing capacity and to impact tests to assess their energy absorption characteristics. Through testing the effectiveness of structural innovations in enhancing the resilience of high-speed vessels is thus ensured, providing useful information for the development of theoretical and numerical prediction models.
