The marine sector increasingly requires safer and more efficient vessels, especially small boats used in critical operations. This study explores the use of Fibre Bragg Grating (FBG) sensors for Structural Health Monitoring (SHM) in a small aluminum boat. FBG sensors were chosen for their high sensitivity, immunity to electromagnetic interference, and capability to provide real-time strain measurements. Nine FBG sensors were installed at key structural locations on the boat. Data obtained from Finite Element Analysis (FEA) was compared with real-time sensor readings to evaluate correlation and validate the SHM approach. Findings show that FBG sensors effectively capture structural behavior, particularly in high-strain areas such as the midship. The integration of simulation and sensor-based monitoring enables proactive maintenance, enhances safety, and extends the vessel’s operational lifespan.
