abstract Non-destructive testing (NDT) is gaining increasing importance in the marine industry, with its application expanding beyond aviation into composite yacht manufacturing. This paper presents selected case studies using ultrasonic pulse-echo, infrared thermography, and laser shearography, performed on representative GFRP samples as well as real-world marine structures. The discussed examples highlight the challenges specific to thick composite sections, diverse defect locations, and the need for image-based evaluation systems. The selected cases address problems encountered by yacht manufacturers and attempt to indicate possible solutions.
