Highly demanding in the fast-growing marine construction industry, increasing revenue and profitability requires advances in technology for cost-effective production in key areas of ship production and ship production management. The absence of information, particularly in the mechanical damage behaviour of marine structures, is addressed by structural health monitoring (SHM), which focuses on providing accurate and real-time information on the state and performance of structures. This research has been focused on Fibre Bragg Grating (FBG) strain gauge has been installed on aluminium boat, with a focus on the first order shear deformation theory. The results, showed the strain value slightly decreased when FBG located at midship area with maximum strain is 563.28 µε compare to rear area with 300.60 µε. This might be effected due to wave development at front area larger than wave at rear of the boat. Stress occurred in this area is very interesting need to be discovered especially for MRO (Maintenance, Repair and Overhaul) for marine structures activity.
